Invulnerability

This power is misnamed: Invulnerability isn't, not really. This power is a matter of the soul producing a shield around the body, reflexively slowing incoming attacks, or otherwose countering anything that would hurt them. It looks like invulnerablity (nothing seems to affect the target) right up until the super gets too exhausted to keep it up, or an attack with more oomph than they cam handle lands. After that, the super gets injured much like anyone else, and usually needs to heal the slow way. Souls recover their energy, however, so an 'Invulnerable' super who just took an injury will often (but not always) still be able to laugh off a normal gunshot.
