Well, to me, Optimus Prime is like a master of military strategy. Sure, cold as he might be when he decided not to rescue Bumblebee, to have Bumblebee sacrificing his life/spark and not waste any time in order to get the AllSpark as soon as possible. Though I do not get his paint job...
Bumblebee, the guardian of Sam. Firstly, Bee-otch? What's up with that? And I think he could be a little bit more attach to Optimus as the G1 Bumblebee did. The G1 Bee-otch... I mean Bumblebee tends to think Optimus as the greatest Autobot to have ever live (much more than any other Autobot does). He is innocent, and petite... I mean, Jazz is smaller than him in the 2007 movie! Bumblebee is supposed to be the small one! Anyway, other than that, Bumblebee is... reasonably similar enough to the G1 Bumblebee, and his music totally rocks.
Jazz. The cool dude. The wild cat. Jazz is one of my favorite... oh, who am I kidding? Jazz
is my favorite Autobot in Transformers (2007). Too bad about one thing, OPTIMUS PRIME IS TOTALLY COLD TOWARDS HIS DEATH! "AW JAZZ"?! Ahem. I think it is nice he is the lieutenant, and takes care of his comrades more than Optimus does. It is definitely better than his "Saboteur" rank in G1. Jazz, the cool kitty.
Ironhide. There are tough Autobots, there are brave ones, and then there are tough, brave Autobots without a mind of a donkey. Ironhide is one of these. The weapon specialist definitely has some cool cannons. Heck, I think his cannon could match up against Starscream's missles.
"You feelin' lucky, punk?"
lol
Yeah, Ironhide is definitely cool. He is the alternative of Kup, or Kup being the alternative of him... whatever. Though I did not hear much of his war stories in the movie, but I guess that is acceptable. I mean, could you imagine Ironhide beginning to tell Spike about how he and Starscream trying to fight it out in the antarctic while he is escorting a fellow greenhorn?
Now, am I forgetting anyone?
Oh yes, phenomenon-man, Ratchet. Being the medic, he is supposed to be the "weak" one, since most medical officers are killed in the movie. But Ratchet ain't too bad, I guess (not as bad as Jazz-torn-helot). Though there is one thing I want to point out. When I first saw Ratchet in the movie, he reminds me of a war hero than Ironhide does. Why? His face. I mean, he looked like old man Jenkins from Spongebob! Maybe you need to be old to be a medic or something. *shrugs* Ratchet, the phenomenon medic.
