What’s your favourite ‘completely out of nowhere’ team-up that they’ve added?

I’m not talking about the teamups as a “I didn’t expect ___ to be so OP”, obviously the actual usefulness of these will be known later.

I’m talking more in the creative sense of not expecting the two characters to teamup together.

Iron Fist and Thing seems so out of left field but I do get the two big punch characters getting one. Also was not expecting Blade and Cap, that seems so random but I love it
