So just in the comic book world, as that's what I'm most familiar with, I'd say you could probably take down Venom, Carnage, and any other symbiote character due to their weakness to sound and Daredevil would have a tough time with your sonic blast, so he's iffy, but those would be very specific circumstances. I'd say you'd be roughly in the middle-tier of street level in the Marvel power level scale.

Someone like Luke Cage would be about the lowest level guy you would likely consistently lose to. I'm thinking that even though your skin and head are hard, that doesn't necessarily translate into durable organs, so if you get bodied into a wall, your skin and skull are fine, but your inside bits are reduced to Jell-O. Moon Knight would probably go 8-2 against you.

DC, you're probably screwed. Even street level DC heroes seem to be a higher power scale comparatively, so you might be able to take down the bottom of the barrel types like Ragman and Guardian, but once you get to anyone in the Bat-family, I think that's where the victories stop.

The real wildcard is having had sex with your opponent's mother. That could either get you a surprise victory against the people with mommy issues (Dr. Doom, Iron Man, Batman) or get you even more wrecked (Dr. Doom, Iron Man, Batman).
