Yusuke is sort of a toned down Goku. Even so he could still pwn Solaris easily and without trying. It almost makes you feel bad for him. Of course Yusuke is super powerful so maybe it’s not really that sad. Solaris gets his first loss. Yusuke wins.

Does Solaris really lose this tho? I can’t picture Yusuke beating one super powered hedgehog, let alone 3.
and do you expect dreager to give an actual good reason to why he believes yusuke can win?
No cause he downplays sonic characters like crazy
Yusuke’s demon mode really makes him a super threat here though. In terms of raw power he should be able to quickly dismantle Solaris’ defenses. That said, him taking on a super hedgehog is another thing but I can’t see Solaris taking on Super Shadow or Super Sonic. The heroes teamed up to take him out in all the timelines but otherwise in a straight fight each one was taking care of business on their end. I don’t think Solaris scales up as high as it would appear
