depends which one ur talkin about G1 megatron turned into a Walter P 38 Pistol which is totaly the most awesome megatron ever
Galvatron uses Megatron and is Decepticons in to his and he uses Megatrons body as Galvatrons
Megatron transforms because when Megatron is in his vehicle mode he can't shoot his normal weapons and when he transforms he can grap, hit, shoot and do other things too.

Megatron
DJ Megatron went by Megatron.
Megatron has strength and unbreakable will. Ironhide has aim and guns, not to mentions he an Autobot, Seeing as the good guy always wins Ironhide would win he might get hurt badly but he would end up winning. Now if it weren't for that fact Megatron. He is bigger than Ironhide and he can move fast. Ironhide is also older that Megatron, that dose give him more experence. Megatron can also turn in to a Cybertronian jet, with guns and such. He can also turn in to a flying tank, Again thast has guns. Ironhide turns in to a Topkick, no guns. So Megatron has a stronger alt. mode and his main form is stronger. Megatron wins this one. Better luck next time Ironhide.
