Who is the strongest LEGO minifigure ever made?

I'm not talking about LEGO video games or only LEGO-original characters. I mean every character LEGO has ever officially made as a minifigure, including licensed characters from Marvel, DC, Star Wars, Harry Potter, etc. If we take the character's actual powers/lore into account, rather than just how strong the physical LEGO figure is, who would be the strongest? For example, would it be Thanos with all 6 Infinity Stones? Or is there another character that is even more powerful? I'd love to...
