The Electro-Grenade is an electric bomb The Turtles use on missions. It is made out of a baseball, batteries, and some metal sticks. After detonation, the Electro-Grenade releases a power electric field for electrocuting enemies.


The Electro-Grenade was used to electrocute Shredder in the episode "Enemy Of My Enemy". But before it struck Shredder, Karai pushed him away and it hit and shocked Steranko and two other Foot Soldiers.

It reappeared in Newtralized! by Donnie to destroy the Kraang Walker. Although, before it hit, Newtralizer shot at it while still airborne, and blew it up.


  • It appears to be a baseball that Donnie modified with electric wires.
