[@Savato] Sure, just something that makes it so that other characters have a chance of beating him. It's not fun if one character has a power that nobody else can defend against. Maybe he's not immune to his own explosions, so if he uses his power to close to himself he can damage himself. I still think that the bombs shouldn't be able to fuse with flesh, however. Maybe it can't bind to organic matter well enough to explode, but still burns. A burn is easier to heal from than having your body literally explode.
