Nuclear Fusion Grenade

The Nuclear Fusion Grenade first appeared in the episode The Enemy of My Enemy when Octagon Vreedle used it against Kevin but because of his lack of inteligence, he forgot to consider the fact that it had the power to destroy the entire Plumbers' Academy space station. Ben (as Ultimate Echo Echo) then took the bomb out far into space away from the Academy and let it explode there, not harming anyone. It's used again in Basic Training in a grenade malfunction as an attempt to kill Magister Hulka.
