How to unlock the Power duo achievement in Marvel Avengers Battle for Earth - Definitive Guide
Don't even need a partner. Simply select co-op in campaign or arcade, and win the battle without switching characters (or maybe you can... I don't really know if it would work) and this achievement will pop.

It's OK to switch characters. The achievement didn't pop for me immediately, I went into another room and left the game sitting at the menu, around 10 minutes later I heard it pop. Weird.

Odd. Maybe because you switched characters?

All you have to do is win a co-op match in either campaign or arcade mode. It should pop up during the results screen.
Note: This one seems to be a bit glitchy for some; restart your Xbox and try again. Refer to the video under "Symbiosis" to see exactly when mines popped.
