Suggested by Sonic Shulk can see the future and he has some pretty good sword techniques. He’ll definitely give Sonic a run for his money. That being said, Sonic’s fast enough to dodge all of his counter attacks and still land his share of blows. I think the difference in ability here is going to be way too vast for Shulk to do much. Once Sonic goes super he just will be too fast for Shulk to even think of landing a hit. Sonic wins.

Shulk is omnipresent, isn’t he faster than sonic? Like isn’t sonic only faster than the speed of light and only low multiversal?
Shulk’s combat speed isn’t greater than Sonic’s though. Sonic’s shown that he can fight at hypersonic speeds and FTL but Shulk has never proven that.
I think it’s more that Shulk hasn’t shown much with his 3rd monado, so Sonic wins with the fact that Shulk never shown much except that he recreated a world
Yeah if Shulk had gotten to show more of his stuff that definitely could have helped him out quite a bit
So im gonna keep this breif because im too lazy to do this and discussing the abilities and their feats of these two is ridiculous
So imma say this
Im gonna assume shulk has all his abilities from lore and game and etc
If its shulk vs sonic from the games shulk wins cause monado 3 is busted as fuck
Plus vision makes it hard for sonic to land hits
But if its shulk vs archie sonic then sonic wins because well rewriting a infinite multiverse is far above shulks league
Yes i know shulk has like a multiversal feat but archie sonic got it even bigger
Agreed Sonic’s really hard to take down in composite. With those archie skills he would basically be ending the multiverse in an instant. No matter how far Shulk peers into the future, it will not be a bright beyond awaiting him
