Abodyguard who turns against the body in his care is a particular menace. This is as true for guardians on the inside as for guardians without.

When faced with foreign cells, these proteins are activated one after the other, in a domino-like effect, eventually forming rings which punch crippling holes in the cell-membranes of the interlopers.
