they do not need to be a fight, necessarily

Here are mine in no particular order

- Captain America's speech to Spiderman in civil war

- Superman's defiance and "No, Sir" statements and, when the other JLA members went down one after the next, winning against all the attacks that a maniac from another universe wanted to use to conquer everything for "fun"

- Captain America's last stand against Thanos in infinity war when Cap by himself went against Thanos with the infinity gem.

- Ben Grimm wading through all the attacks and defences of Dr. Doom at the battle of the Baxter Building and finally hurting Doom's hand and defeating him

- Superman's confession of love to Wonder Woman just before they set off a nuclear explosion at ground zero together, and Wonder Woman's reaction
