Power-ups allowed, and to say a few things:
First, the thread is misnamed because I was going to originally make it Mario v. Samus but know nothing about Samus.
And so I decided, "What if the two emblems of Sega and Nintendo beat the living crap out of each other?" So it was changed to Sonic v. Mario.
I would have changed the title if I hadn't forgot.

Second, touche (the E with a little slanty thing over it, you know what I mean) to previous poster with their siggy pic, which was a clip from Clows, which is at weebls-stuff.com
Third, I forgot.
