John Wick vs. Caillou, I’d love to see that little fucker die.
For me personally, I would love to see Alien X from Ben 10 fight Q from Star Trek. Both characters are known to warp reality and are omnipotent beings. Q would try to use his illusions to trick Alien X, but Alien X makes things happen by using his thoughts. We can exclude the debating floating magic mirror just for this occasion. Without those faces, Alien X would be just as powerful and be busy kicking ass. I would like to see him battle the celestials from Marvel and Doctor Manhattan, but I prefer him battling Q because both characters stand out from their own omnipotent species.
Since I ended up bringing Ben 10, I would like to see his aliens battle other characters

I want Mortal Kombat 11 to include Rambo so that we can see Terminator vs Rambo. That was one of the hottest debates when I was in the middle school.
