Ultimate X-Men

A new mutant has appeared. He awakens to an empty house. Everyone around him is vaporizing on sight, so he flees to seclusion. Wolverine tracks him down and offers him a beer. It seems the young man's mutant power is to destroy all organic tissue within a given radius, including 265 people. Wolverine is there to make sure the world never finds out a mutant is responsible for that much death, intentional or otherwise.
