The originals... ok, not exactly, but the original named "The TransFormers" anyway. Take THAT, Diaclone! Generation 1, Generation 2 - Removable fists? Check. Unlicensed vehicle modes? Check. Kickass tape deck robot with transforming cassette minions? DOUBLE CHECK!!!
Intersting that you left out Bruticus. The idea with him is that all 5 Combaticons have an appreciation for some part of warfare, making Bruticus a good soldier.
Neither he nor Abominus have US bios, their Japanese ones feature nothing of note.
The Scramble City thought is an interesting one. Swapping limbs until the perfect composite is reached. Shame that wasn't explored back in the day, would've made for a challenging story and a good cross-sell of toys.
Abominus WOULD feel proud, but he's too busy trying to work out how else he feels.
Hungry?
Disgusting?
Sadistic?
Paranoid?
Genocidal?
All of the above??
