Not sure if Thor and Hulk qualify. Especially since most times they're "friends". (Technically Vitriolic Best Buds, but ultimately friends.)
If the heroes are Vitriolic Best Buds, this trope doesn't apply.
"Also, be aware, there is no such thing as Foe Yay where this trope is concerned. Do not read into the dynamic between the characters as unconscious flirting — they fucking hate each other, period."

How well does it match the trope?
