Why would it have to be so flashy? All it needs to do is make Doug invincible. That's not the same as being strong, or able to fly. Rather, it would just make him unable to be defeated. This isn't quite the same as invulnerability either; rather, I think this song would just result in however many minor deus ex machinae are needed to prevent defeat, though perhaps not enough to ensure victory.
If you want something more showy, I'd try her "Hit Me With Your Best Shot" which would probably make Doug a magnet for any ranged attacks made by any combatant. But that's okay, since as the song goes, Knock me down, it's all in vain/I get right back on my feet again
