Ok guys, dig this thought process I'm about to drop on yall b*tch @sses;
(Just kidding, I just saw the movie last night and all the cursing is coming through)
Anyways, I see an 'age' difference between the bots. Megs and Optimus seem to be of about the same age-group and caliber, so I'll start with them. These leaders of the opposing factions act and perform as if they are (in earth terms) in their late 30's, very early 40's.... and in Cybertronian terms, it takes a couple millenia to get to that age. The two are much more powerful and intelligent than the other bots, and it shows.
With that said, I'm assuming from character traits and references that of course above them is Jetfire, and the Fallen..... before them are Ratchet (39 +/- well-studied), Ironhide (30+/- trained/seasoned warrior), Soundwave (40+/- trained/seasoned comms specialist)..... and before those guys are the 'youngins'; Bumblebee (19 +/- emotional scout), Jazz (R.I.P. 24 +/-), Sideswipe (23+/-)....
The Twins are (in my opinion) between the ages of 12 and 15, and if any of you had a childhood with ruffians, or troublemakers of any sort, then you might begin to see where I'm headed right about now;
Kids are dumb yo. they watch TV and mimic it. They make up rap dances to the Lion King and whine about getting a cell phone that costs 400 dollars because they just want it. They put on the appearance of whatever they think makes them cool. Have any of you walked out of the house in Junior High and been criticized for what you wore, or saying 'like' after and before everything, or speaking 'dumbed-down' so that you could fit in?
The Twins did what Jazz did, respected the 'coolness' of this generation and embodied
their own version of it. They even competed over who got the green car remember? I mean they just want to be 'fly' and thats how they think they'll gain respect (in my opinion).
Sorry I'm so opinionated, I'm from D.C.
