When Leatherhead gave the cell to Michelangelo, Donatello used it to power the Shellraiser but The Kraang returned and stole the cell, because of Timothy out.of-control driving. In the episode TCRI, The Kraang finally use the power cell to open the portal. In Showdown Part One, Leonardo managed to destroy it and destroy the portal once and for all with some Kraangs inside of their Kraangdroids and Traag, when The Kraang was going to bring the Technodrome. The Kraang Power Cell resembles a glowing crystal shard trapped inside a glass container. The Kraang's Power Cell's first appearance was in It Came From the Depths.
