This is tricky, but very possible to pull off in most if not all versions of Sinistar. With only no lives remaining, when you fly up to a fully build Sinistar, he'll suck you in and eat you. However, if a UFO is around when this animation is occuring and you get shot before being eaten, the lives will be -1, which will loop back around to 255. Have fun!
