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.
Ironhide, because he has lots of guns.
I say Optimus Prime. Voltron's pretty darn big, but he doesn't have the matrix.
Megas XLR ftw.
Optimus Prime.
optimus prime
I think optimus prime should win.
Optimus
optimus prime
Optimus Prime.
optimus prime and predator
Optimus Prime, he is a prime and much bigger than Sideswipe.
bumblebee jazz and optimus prime
mabye King Kong or Optimus Prime because King Kong can throw Optimus Prime in the water and break him and win or Optimus Prime can use his swords to stab King Kong and win
No Optimus is a prime and Bumblebee is not Optimus is also at east twice astall as Bumblebee so no Optimus would win
Optimus Prime. Shockwave's pet (Driller) has already been killed by Optimus and that was Shockwaves best way of fighting.
