The Marathon entry was incorrect vis a vis the storyline. I amended it to fix the errors.

How is this different from Heart Is an Awesome Power?

It's a Sister Trope. Basically, A Lethal Harmless Power is a power that's good on it's own, but also happens to have a use that can kill or seriously hurt others. In terms of reaction, a hero finding out that Heart Is an Awesome Power will be happy, while one figuring out that their harmless power can be lethal will be horrified.
