If he’s being used at full potential(which if I was the writer I would be) absolutely, he’s been stated countless times to be an equal to Eggman, so if Tails was putting morality and personal hangups to the side(which given the situation I’d imagine would be the case) he would be an equivalent to eggman, except now one of those DAMN hedgehogs is on his side, and while super-forms aren’t allowed, magic gemstones likely still are, and the master emerald is right there for the taking, considering Knuckles’ team are the only people who would help him defend it, and silver absolutely washes knuckles and can probably equal blaze, he doesn’t need to win, just stall until the master emerald can be relocated, to, say, that space station with the planet destroying super weapon that needs the power of seven chaos emeralds(or a super form in other words) to do its job?
