Electric Slime is a sticky substance which can electrocute whatever it is attached to. It was used by Rage Shenron, the Shadow Dragon of electricity. Rage also used it to become much larger and stronger, which is known as Electric Slime Body Build.
Rage Shenron can generate and control the massive amount of electricity-draining pink ooze. This Electric Slime can apparently replicate itself by absorbing enough electricity, but water will cause it to short out and even explode in large enough masses.
Rage uses his Electric Slime to destroy Goku and Pan, who confronts him in order to restore the Earth and the Dragon Balls. Goku and Pan cannot escape from the sticky slime, as it stops them in their tracks. Then, it electrocutes them, which seemingly kills them. However, they recover from the attack with little harm, much to the shock of Rage. Rage then uses it to make himself much larger, thus forcing Goku to turn Super Saiyan 4. The slime is soon defeated when it rains in the battlefield, making Rage's body short circuit.
