Just combine the powers and abilities of Rick Sanchez and Batman into one character. I suggest going to VSBatles wiki (not really the best one but I guess it's good when you need to look up for the powers and abilities for specific characters), search them up and choose which power you want.
Note: Please, keep in mind that this is a debate community, meaning that people are debating characters in a "who would win" manner there... and they are veery serious about it most of the time. I don't suggest you going there and asking the questions you have in regards to your story, since I don't think that that's allowed there (if you do plan anyway, please check their rules in advance because I seriously don't want you to get banned from any fandoms wiki).
Edit: Also, I forgot. VSBattles have their own category of powers and abilities, but I really suggest searching them up here after you looked up the characters. I know that this is weird advice but the thing is.... Superpowers wiki's and VSBattles wiki's have entirely different purposes. One is about looking for superpowers that you need when creating character and a collection of superpowers that exist across fiction, the other is for purely debating purpose and powerscaling characters that exists across fiction.
