Waluigi (Mario Bros.) vs Oro (Street Fighter). If you have a UniVS template with a picture of the two to replace the thumbnail, feel free. Comment your opinion on who would win and if you'd like to see this as an episode.
these two are more treated as jokes nowadays rather than being taken seriously. Waluigi was seen as a second rate evil Luigi, now he's become meme. Oro is just described as some old guy with one arm, most people don't even take him seriously enough to learn he hold his left arm behind his back, they actually think he's and amputee. That being said, these two are actually, surprisingly cool. Waluigi uses crotch chops as a victory taunt and has a bunch of weird abilities you wouldn't expect, like water manipulation or teleportation. Oro on the other hand, travels by standing on the outside of jets, and has powers like pulling out a piece of the sun to throw, or hiding his left arm, just so he doesn't kill his opponent. The theme of this fight is surprisingly awesome characters that are often overlooked due to having ridiculous qualities about them.
Now this is a little tricky, I'm not actually sure if Waluigi scales to the rest of the Mario verse, his most prevalent feat of beating up Bowser came before the massive increase in Bowser's stats in Galaxy. I'd assume he does, since he has to stand against them in sports events. That being said, although Oro's sun feat is impressive, Waluigi scaling to the rest of the verse would put him over what he needs to surpass Oro. In this fight, it really will be Waluigi Time!
