That's the problem with Skrulls. You don't know if your friends are really your enemies.
Back before 5th ed came out, I played the half-human son of Super-Skrull in a DC/Marvel combined universe. My character only had the powers of the Human Torch, but retained the full shape-shifting powerset. I also managed to con the GM into allowing regeneration on the grounds that I "shape-shifted my wounds away."
I was sad the game only lasted four sessions. I was looking forward to the big battle Royal between the Avengers and the Justice League (Thanos and Darkseid tricked the two teams into thinking the other team had been replaced by Skrulls. And this was years before Secret Invasion!)
