ITT Give me a REALLY GOOD comic book fight that hasn't happened yet

I'll start with Iron Maniac versus the Maker. Ultimate Reed is annoying, too arrogant and too smart to make the mistakes he always does He's like the MCU Riddler at this point, all that elaboration just to screw himself over every time. And they literally made sure there's one in every universe now, what the hell is that?

So if he caught the attentions of an alternate universe Tony Stark with a vendetta against EVERY Reed Richards in EVERY reality, I would find that quite satisfying!
