Ha! so true, the current Optimus just uses guns mostly, still got melee like the axe but.....actually the bayverse one went from mostly range from 1-3 to melee 4-5 if you think about it
i say the most powerful optimus prime is T1,2,3 because in that form he would dish out some major damage and bro was becoming ruthless and to top it off...While dishing out damage bro took alot of damage and kept moving like a beast
