[Dragon Ball][Marvel][DC] Is there a comic equivalent of Mr. Satan?

I’m talking about someone who just straight-up doesn’t believe in superpowers, no matter what. Someone who would say that Superman actually hangs from a wire , or is wearing secret laser-emitting contacts. If they were in Marvel, they might think that Thor uses smoke and mirrors to make it look like he’s controlling the weather, or that the Hulk is just Bruce Banner piloting an animatronic from the inside.

Does this character exist?

Not exactly super powers, but DC has a character who refuses to believe in Magic. Dr. Thirteen spends his time trying to prove that magic doesn't exist. He even dated Zatana for a while, and still thought she did everything with smoke and mirrors.

The fact his belief is so strong makes him slightly resistant to magic. Basically he thinks it's fake so strongly that magic actually stops working correctly around him.
