I've always thought the concept of "invulnerability" was retarded. Nearly every character that's supposedly invulnerable has taken damage at some point. By definition, invulnerability means "impossible to damage or hurt in any way," and even the VS Battle Wiki defines it as "the power to be immune to conventional harm, requiring something like durability negation to bypass." Yet we have characters like Superman and Super Sonic, who are the poster children of invulnerability, and they have been hurt multiple times. Super Sonic can drown, and Superman has a long history of getting injured, bleeding, needing recovery time, and even dying. How the fuck does someone with invulnerability die from anything other than old age? You can say he has high durability, but he's not invulnerable. Invulnerability is a sham.
