This is ScrewAttack's next Death Battle. When bested by their rivals over and over again, the evil scientists had no choice but to make robots to counter the heroes, made to be better in every way. Metal Sonic; Eggman's robot version of Sonic, or Zero; Wily's rogue creation turned Maverick Hunter. Which of these robots would come out on top?
I think Zero might win this one. As usual, I'll post my argument in the comments. Who agrees, who disagrees, and what are your arguments?
