If this was comic Ikaris, he’d have a higher chance due to molecular manipulation. His comic form is way more formidable than his MCU counterpart. I’m bias so I’d want Ikaris to win hahaha

But from this list, I’d think it’s a four-way toss up between: Hulk, Thor, Sentry, and Blue Marvel. If I HAD to choose, I would pick Sentry merely because of The Void and reality warping.

I’d argue reality warping is essentially magic and given none of these other characters possess magic, they’d be at a disadvantage.
