Quote:"I Will Survive" has psychological side effects on him -- he refuses help and eschews teamwork for its duration -- not always a wise course on Warriors-level missions.
Well, regarding the invincibility being too overpowered, I could see that if it weren't for the fact that I seem to recall a comment made regarding another song ("I Will Survive," maybe?) that would make Doug tough enough to float merrily along in the heart of a star. There's not too much difference between that and invincibility, to my mind.
As to whether "Invincible" is overpowered, well, the song says pretty much that he will be undefeated. It says nothing about guaranteeing that he will do any defeating of his own.
