Well I saw a thread on another site about what they would change about the Bumblebee film and it got me thinking about what I would of done this is assuming this movie is a reboot, I wouldn't drastically change the plot or remove any scenes besides the part where Bee
Goes all "evil iron giant" on those soldiers or at least tone it down to just have him be angry and about to go violent but Charlie calms him down before he does in a call back to the 2007 film where Sam calms Bee down after S7 free him. and also the one brief, minor bit where shirtless, popular guy from Charlie's school and the mean girl are acting flirty since it didn't add anything to the plot and it was the one scene that made me uncomfortable alongside the part where said girl is eating a corndog which gave me weird vibes although it could just be me.
The following contains some spoilers for the movie might seem like I'm talking about 20-40 minutes of stuff but all of the Cybertron stuff is only another 10 or so minutes on top of the existing 3 minutes, it goes by fast like the actual movie and a lot of the details are brief.
I loved the Cybertron scene although I would of liked a little more context to what was going on and showing more of how the Autobots were this small scaled Resistance and how bad their situation is, so I would of started with a "recreation" of the opening scene to the G1 cartoon where we see Wheeljack and Bumblebee stealthily stealing some energy conductors from a Decepticon base because Wheeljack needs them to fuel the escape pods that the Autobots use in the film while, they have colorful banter and stuff to establish their personalities like Wheeljack explaining why they can't use an Ark class ship due to Bee complaining about using the cramped up pods, Bumblebee would accidentally alert the Decepticons to their presence and the two go on the run in a fast paced Cybertronian car chase by a few Decepticon cars who's designs are inspired by the Battle chargers and have various different colors and heads such as Battlecharger heads, heads with proper faces and TFP/FOC Vehicon heads, that are led by an Earth Wars inspired Barricade, he wouldn't be a big part of the film only on Cybertron just to sorta feed that whole Bee/Cade rivalry that uh wasn't really obvious in Bay's films, Wheeljack would be pulling a sort of Cybertronian truck bed with a laser turret to carry the conductors and Bee that he would use to take out most of the pressures outside of Barricade who gets injured similar to when Bee shot Barricade in TLK, that would sort of homage Wheeljack's van turret without the whole weird scale thing of Bee being inside Wheeljack. The car chase would feature Velicitron inspired ramps and stuff with the Decepticons creatively switching between robot and alt mode to gain the advantage.
Mean while we see Optimus entering a small and hidden underground outpost located in Iacon right by the with an open entrance and guarded by a couple Autobot grunts (Their colors and general appearance are inspired by Autobot redshirt characters Deadguy and Cannonfodder with more G1-like designs and are named as such as well, the only named generics here.) walking past and taking note of the Autobots in the big but narrow hall way he's in and occasionally greeting some of the Autobots which includes the Autobots that we see in the film in addition to a few others like a complaining Huffer and a cheerful Hound who uses a Cybertron-edited version of the Jeep Bumblebee design with different colors, head and shoulder gun, it would cut back between happy down time perspectives such as a group of Autobots drinking some "Energon/Nucleon/Oil" stuff including one with a face plate pouring it in some hole/port on his shoulder or chest to cynical ones where Autobots are in despair or discussing about how their losing and how their all going to die, to wounded Autobots being treated by Ratchet and a couple assistants of his (With colors schemes inspired by Ratchet redecos such as one having the colors of the two movie Ratchets decos) but witnessing one of the patients dying with Ratchet at his side would sadden Prime and would somberly comfort the medic and giving his condolences which would establish how close of a bond Prime shares with his soldiers and establishing character before moving on to the room at the back of the hall which is being guarded by Ironhide and Brawn to show that it's an "important" room.
Optimus would enter the room to talk to his 3 top lieutenants among the group Prowl, Cliffjumper, Jazz (He hasn't been on the big screen since 2007 so it would be nice to see him as well as be buddies with Cliff.), and they would discuss the Autobot's lack of resources, Wheeljack and their plans to leave Cybertron and establish a base on another planet and Prowl (Who would be a notable presence in this scene because he hasn't been in a movie yet so establishing his logical personality and being Primes second in command would be a nice on screen character establishment for him, also the Earth Wars inspired Barricade shares the same body as him with a different head which saves on budget the same way that Bee/Cliff, Ironhide/Ratchet and the Seekers do.) after going through a list of planets that Jazz's Special Ops group has monitored name dropping Perceptor with some planets having names of various planets from the franchise like Nebulos and Charr with a notable line about not going to the planet Quintessa due to the bad "judging" from the inhabitants despite it being known as "The planet of life", Prowl finally pulls up Earth and Optimus chooses it due to having a "gut feeling" that it would be the best place, the 4 Autobots debate over who to send with Cliffjumper suggesting Bumblebee, with the planet and scout decided Optimus contacts a rather beat up Ultra Magnus in a hologram (White recolor of this film's Optimus but with a face instead of a face plate, voice by Micheal Ironside) who is leading the rest of the Autobots at the Iacon capital (that Arcee mentions in the actual film) to cause a distraction so that Prime's Autobots can leave, he's not on screen for long but establishes his loyalty and friendship to Prime as well as his sense of duty.
Afterwards we cut back to Deadguy and Cannonfodder who are engaged in a Red vs Blue inspired conversation about their importance or rather their lack of it in the Resistance compared to heroes like Ironhide and Ultra Magnus as well as how awesome Optimus Prime is when Deadguy decides to stretch to prevent stiff gears due to being in his words "Being still for a whole slagging mega-cycle" Cannonfodder tells him to get down with Deadguy scoffing at him confidently stating that with Optimus and other Autobot big shots around around there is no way he could die just as he's sniped in the head by one of many Deceptions in a big army approaching the base with Shockwave at the forefront, Cannonfodder would panic and run into the base without closing the gate and alerts the other Autobots to the Decepticons presence just as he's shot in the back by Shockwave leaving a huge hole in his torso as the young Autobot lifelessly collapses into the arms of Prime as the latter reacts in distraught and orders the Autobots to retreat to the nearby launch pad and contacts Wheeljack and Bumblebee telling them to meet them there, when a generic Autobot asks how they were found the camera pans to one of the "lampposts" with a close up of the Decepticon symbol on it as it transforms into Soundwave kills the Autobot.
With the Autobots on the run and Decepticons in pursuit, Optimus makes a bold plan to cut off their pursuers by blowing up a large bridge after crossing it, they do so with the land base Decepticons being cut off Shockwave orders Starscream to send his Seekers to bombard them, instead of going himself he sends his second in command Blitzwing who is introduced in this scene interrogating an Autobot straggler with the same body type as Bumblebee (Different colors and head), with the Autobot refusing to give information Blitzwing takes his optics before killing him. (Blitzwing has a hobby of robbing Autobots of an important body part and letting them suffer before killing his victim) so Blitzwing leads the Seekers that we see in the beginning of the film but also including the Seekers from the first episode of the cartoon Sunstorm, Hotlink and Bitstream (I'll get to them later) in an assault bombing fleeing Autobots and pinning them at the location the Autobots are at the beginning of the actual movie, with the Autobots setting up good positions to shoot down the flyers the Decepticon Seekers are forced to land on ground and engage in a fire fight that is mostly equal sides although it takes a turn for the worse when Sunstorm's group set up on a good flanking ledge and rain fire down on the Autobots...literally as Hotlink uses a gun that shoots flames in grenade/mortar like projectiles so not a straight up flamethrower like in the original episode.
As the Autobots are dealing with the chaos, Wheeljack and Bumblebee are almost at the launch pad when it turns out their current route is leading them straight towards where the Seeker squad is, however the 3 Seekers notice them and attack the two in a similar matter to the similar situation in the G1 cartoon, there would be a funny bit here where Bitstream orders Sunstorm to melt those Autobots down only to be met with Hotlink's sarcastic retort that "I'm the one who actually shoots fire around here in the first place remember." Thanks to the firepower Wheeljack and Bumblebee are forced down to where the other Autobots are and the two catch up with Prime and discuss about getting the conductors to the pods but being unable to due to the Decepticons firepower, Bumblebee gets an idea about going around and attacking them from behind, although concerned about Bee's safety Optimus agrees to the idea due to the lack of options and Bee transforms to vehicle mode and heads off to the seekers, seeing the Autobot leave the group Blitzwing realizes what he's going to do and heads off alone to stop him, after a brief air chase Bumblebee out smarts him by driving up a wall using magnetic wheels, transforming and landing on top of the Decepticon's tetra jet form he "jet judos" the Seeker second in command right into a wall sort of like what he did to Skyquake in Transformers Prime, afterwards he continues on his way saying "Thanks for the trick Windcharger." (Also yes the Decepticon Seeker that Bee pushes off the ledge at the beginning of the film is Hotlink and the two other Seekers he knocks a side is Sunstorm an Bitstream.)
Afterwards is where the actual film begins with the Decepticons breaking through the front lines and the Autobots losing contact with the Capital, only changes here is that right before Brawn's bit where he gets shot we see Acid Storm take a lucky shot at Prowl who's mouth foams orange smoke from the corrosive shot he doesn't die immediately and Ratchet tries to help him with Prowl visibly moving and squirming in pain although we don't get to see if he actually dies leaving his fate ambiguous so on one hand it homages the 1986 film yet leaves room for Prowl in the future, also somewhere during when the Autobots are first pinned we get a bit with Cliffjumper, Hound, Arcee and Jazz with them partaking in friendly banter, the short scene sort of focuses on Cliff most since he's the subject of the conversation since he pulls out a movie version of the giant gun he had from the first G1 episode out of nowhere and takes a dangerous position to take out some grouped up Decepticons, the other 3 Autobots sort of jokingly tease him about his reckless fighting style stating that something like that is going to kill him someday (
)
Another difference is that in this version of the film Cliffjumper is assigned with Bumblebee as his body guard and partner and the two go to Earth, several pods are shown going in groups with one of those being Ironhide, Ratchet and Jazz as a callback to the 2007 cast. So after the pods take off we cut back to the Decepticons who are regrouping and killing off any Autobot stragglers, this is our first proper introduction to Shatter and Dropkick who are taking on a big Autobot (Think of the big brutes with the shields, hammers and back weak spot from WFC) the two use team work and trickery/manipulation to take him down, afterwards the two walk back to the gathering Decepticons notably Shockwave, Soundwave, Starscream, Blitzwing, Acid Storm Thundercracker, Skywarp, Sunstorm, Bitstream and Barricade and discuss how to proceed the fleeing Autobots, Shockwave decides to have Seekers chase the pods instead of wasting warship fleets to conserve resources, Blitzwing having being mocked by his fellow Seekers for his humiliating defeat at Bumblebee's hand with Starscream rubbing salt in the wound by demoting him and replacing him with Acid Storm publicly and out loud the embarrassed ex-second in command picks Bumblebee's pod to hunt and leaves Cybertron in hot pursuit while most of the other Seekers pick their own targets, afterwards when the Decepticons start heading back to their headquarters in Kaon Shockwave who is still monitoring the pods notices that the ones belonging to Bee and Cliff are heading in a drastically different direction then the other Autobots and asks for volunteers to join to track them due to suspicions that the Autobots have some big plan, Barricade confidently volunteers first and the movie initially makes you think he will be the one to go but is turned down by Shockwave who states he needs someone who is actually reliable (Thundercracker and Skywarp snicker at the Decepticop's expense) with Shatter who volunteers herself and Dropkick, Shockwave lets the two take his personal shuttle.
And that's the end of the Cybertron stuff.
Bumlebee and Cliffjumper land on Earth where Jack Burns and the other Sector 7 agents are doing their training, the two Autobots land in different spots and are pursued by two different Sector 7 squads with Agent Burns actually calling in the Air Force this time, Cliffjumper spots the quarry and tells Bumblebee to meet him there, Cliffjumper unlike Bee does not scan an Earth vehicle and as such has trouble driving on the bumpy dirt road, so as in the movie Bumblebee gets cut off from escaping into the quarry tunnel although this time after S7 surround him Cliff shows up from behind and aggressively tells them to put their weapons down although Burns refuses directly challenging the trigger happy Autobot although through his words Bumblebee calms them both down and after making it clear that neither of them want to hurt the humans Burns orders his men to put his weapons down and calls off the Air Force, one of the pilots replies that their detecting an unknown bogie approaching from the atmosphere and at that moment they are taken out by Blitzwing after scanning one of the planes he proceeds to destroy all of them in a scene similar to Starscream taking out F-22's in the 2007 film, afterwards the movie proceeds very much the same with Blitzwing taking out the S7 forces as well as knocking out Cliffjumper who took the brunt of the damage shielding Bumblebee, the Blitzwing fight proceeds the same except after Blitz throws Bee off the cliff and comes down to finish him off Cliffjumper wakes up in time and shoots Blitzwing in the chest with his Glass gas gun. With Blitzwing enraged and distracted Bumblebee does the whole blowing him up with his own missile thing, this time Blitzwing's remains such as his head are more intact, after checking up on his heavily wounded comrade Cliffjumper hears Shatter attempting to contact Blitzwing from the dead Seeker's "radio" and how she detected his signal but has lost contact and is on her way, Cliffjumper and a limping Bumblebee attempt to make their way out of the area but after a few steps Bumblebee falls down and scans the Beetle before waking up one last time to awkwardly Transform into it (I was confused about what happened in the actual movie and how he ended up in the junk yard).
Cliffjumper in a rush takes the form of a red Porche 924 Turbo and tows the unconscious Bumblebee as the sun sets, when he detects the Decepticon's ship near where they are he is forced to hide Bumblebee in a ditch and split up so they don't both get caught and makes the cons chase him, the next day "Uncle Hank" (the guy who gives Charlie Bee) comes across the VW while he's on a drive and arranges to take the abandoned car back to his junkyard, several months pass and we go to Charlie's perspective and life just like the movie and all proceeds the same until she activates Bee's radio where we cut to Shatter and Dropkick who use the ship to contact Shockwave (ala the G1 cartoon screen and all) who have traced Cliffjumper to a closed factory at night time the cyclopean Decepticon tells them of his plan to use a space bridge to send the rest of the Decepticons to Earth to loot it of it's resources but needs specific coordinates from a powerful enough transmission source to be able to accurately use the bridge, the Autobot who's been on the run all this time has devised a trap made from human materials and plans to ambush the two Decepticons then go back for Bumblebee, his reckless plan goes well at first with him managing to catch Shatter, blow up the Decepticons ship leaving them without a means of contact and goes to town with Dropkick using a red version of the hammer that Bumblebee used in TLK and beats him to near death but just as he's raising his arm to deliver the final blow Shatter having freed herself cuts off his arm, the Cliffjumper interrogation and death scene goes exactly the same way as the actual film except on Earth this time and not on Saturn's moon, afterwards the Decepticons scavenge parts from Shockwave's ship and Shatter upgrades her and Dropkick with flight tech which is why they can triple change to air vehicles.
After this point there isn't much difference from the actual movie except for a brief scene inside the Sector 7 base in Hoover Dam where Shatter and Dropkick come across the remains of Blitzwing and Cliffjumper that S7 has recovered, Shatter has a conversation with Agent Burns explaining that while he was also a "Peacekeeper" Blitzwing was a violent, disobedient contract freelancer loosely associated with their forces, she also explains that Cliffjumper was one of the most vile warlords on their planet and is the reason that the otherwise friendly Bumblebee is such a bad guy having corrupted the young soldier who she says was a former "Peacekeeper" cadet prior and that she's trying to capture him so she can deliver him to the Decepticon authorities for his own good so they can help him, while Burns doesn't believe her because of the contradictions to his previous interaction with the 3 Transformers he goes along with the plan anyways due to wanting to protect Earth.
The Cybertron hologram flashback would be the same except after crashing the Seeker he is riding to the ground Optimus gets harassed by Ramjet, Dirge and Thrust who at this point aren't Coneheads but he wipes the floor with them with ease, Starscream arrives afterwards mocking the 3 Seekers lackluster performance calling them a bunch of "Coneheads", Soundwave ejects Ravage and the scene continues on like normal.
After this the film and final is the same until the end during the battle Dropkick taunts Bee about Cliff's death and waves his Glass Gas gun around, after he chains up Dropkick with the latter taunting him about the chains being unable to do anything to him Bee picks up the gun and shoots the Decepticon with it before tearing the scared Decepticon who pleads for his life despite him not sparing anyone himself, apart with the chains, Bee sadly stating afterwards with the radio that killing him was for his friend but that he must save his new friend, after Bumblebee shoots the "wall" behind Shatter, floods the area and getting "saved" by Charlie it seems all is alright until a heavily damaged Shatter ambushes them easily knocking down the tired out Autobot and crushes the Glass Gas gun at the cost of it "shattering" her hand, as she prepares to execute the Autobot once more, a voice sounds out from nearby asking her to lay down her weapon and surrender, as the recently arriving Optimus Prime approaches them Bumblebee takes advantage of a refusing and distracted Shatter kicking her away however he accidentally kicks her towards Charlie who Shatter takes as a hostage, as the Decepticon angrily raves on about her cause as well as how nothing will stop them since the Decepticons already know where Earth is and will arrive one day regardless, Optimus again tries to reason with her but to no avail, as it looks like there is nothing they can do Agent Burns shoots Shatter from behind with a rocket which causes her to drop Charlie, as the Decepticon raises her weapon to kill the Agent, Optimus shoots her as he notes with regret that despite all of the things she has done under the Decepticon name he would of still accepted her surrender.
Optimus then formerly meets Charlie and Jack Burns who apologizes to Bumblebee about hunting him and admits that he was wrong about him, he also lets the two Autobots know that they have Cliffjumper's body although it's impossible for him to give it to them since the rest of S7 still assume that Autobots and Decepticons are the same, just like the movie Burns lets them go and salutes Bee.
Optimus, Bumblebee and Charlie head to the San Francisco bridge where nearby Optimus Prime has hidden a trailer that within contains Teletraan 1 which he will use to call other Autobots to Earth he leaves Bumblebee and Charlie alone so that the two can say their goodbyes afterwards the two Autobots head out together (Bee still scans the Camaro)
The scene with Bee and Prime at the forest is slightly different, a set up Telatraan 1 is set up in the background, while Bumblebee asks how he got off Cybertron Prime just says he will tell him at another time and then thanks him for defending Earth and the two watch the other Autobots arrive.
A new after credits scene, S7 scientists are developing cryo-freezing equipment inspired by Cliffjumper's Glas Gas gun as well as conducting energy experiments on the remains of Blitzwing who is hooked up to a intricate machine using the same tech as S7's Electric guns, after a few tests with no results they go with a higher voltage and Blitzwing's optics briefly light up going from scared and pained to a hateful rage before shutting back off.
The End.
My god I spent 5-6 hours writing this. (Can I get a writing job yet? I just need a Proofreader lol)
