Biography
In "You're Fired", Plasmus recklessly attacked a distant planet that had a massive nuclear core on it. The nuclear core was very sensitive and if it was destroyed, the whole planet would be vaporized. Plasmus started punching the core, in hopes to blow it up, giving himself a massive amount of power. The Teen Titans showed up and tried to stop them, but Beast Boy stopped to think about what kind of animal he should turn into when fighting Plasmus. He took a ridiculously long amount of time to think about this, while his teammates got beaten up, as they could not defeat Plasmus, without the entire team, being present. When Beast Boy finally settled on what animal he wanted to turn into, Plasmus landed the fatal punch on the nuclear core, blowing the planet to smithereens.

Plasmus showed up later in the episode, attacking Jump City back on Earth. The Teen Titans fought with Plasmus but required the assistance of Jayna from The Wonder Twins. Jayna took on the form of a rhinoceros and Zan intentionally sabotaged her heroism, by taking on the shape of ice, causing Jayna to slip, while charging at Plasmus, and fumble. The Titans were slammed against a wall by Plasmus and once again, failed to defeat him.
