SCORPONOK. No contest.

Trypticon just had a re-issue so he can sod off. Omega Supreme is great but ol' Scorps just owns him in the coolness dept. Plus, the original Scorponok is one of the greatest Transformers of all time. Anyone who thinks otherwise needs to take a good hard look at themselves and question their grip on reality. Hence, he has already proven his RIGHT to a 21st Century update.

SCORPONOK. end of.
