Funny that this is also something referred to recently in the MtMtE comics.
It depends on the universe I suppose, each one varies and differs, I think most of the G1 characters that fit the bill have been mentioned.
What about BW? Animated? It'd be interesting to compare numbers or percentages on super elite warriors for both factions.
BW:
Maximal:
Optimus Primal
Depth Charge
Tigerhawk
(so mostly due to enhancements, Depth Charge is the only strong non interfered with character.)
Predacon:
Megatron
Rampage (again an experiment)
Animated:
Autobot:
Magnus
Grimlock (?)
Omega Supreme
Decepticon:
Lugnutz
Blackout
Megatron
Hrmm not as many as you would think.
Looking For: Wreckers Saga TPB Collection (with Requiem)
