Slycerak, Tesela (テサラ, Tesara?) in the Japanese version, was a Mechtogan that was created by Fury in the Doom Dimension. He is one of the four Mechtogan that make up Mechtavius Destroyer. He was released in Bakugan: Mechtanium Surge.
Slycerak is an agile and nimble Mechtogan that can maneuver his way into multiple attack modes. When threatened in battle, Slycerak's chest transforms to unleash dual spinning saw blades that slice through even the strongest of materials. With metallic blades on his forearm and a poisonous stinger tail, Slycerak is one of the most lethal Mechtogan.
In Wiseman Cometh he combined into Mechtavius Destroyer a second time, but was defeated once again in a similar manner to his previous appearance.
In Countdown to Doomsday he appeared alongside Coredegon, Exostriker, and Mandibor. Slycerak easily defeated Betakor in a single blast. Later they combined into Mechtavius Destroyer and defeated Dragonoid Destroyer for the first time.
In The Eve of Extermination, he and the other Mechtogan battled against the Brawlers and combined into Mechtavius Destroyer. They were winning until Dragonoid Destroyer summoned Flytris and Thorak, who both combined into Duomechtra and defeated them.
In Enemy Infiltration, he was fully resurrected alongside Exostriker and Mandibor. Later they battled against the Brawlers and won.
In End of the Line, he was destroyed by Dragonoid Destroyer with his fellow Mechtogan.
Slycerak is #18 in the Mechtogan series. It has five BakuNano holes; two on each arm, each shoulder, and one on his "tail".
- Slycerak's posture, extended buzzsaws, and leg position in activated form make him appear eerily similar to Faser Titan; more so than the Titan's counterpart Silent Strike.
- If Mechtavius Destroyer's victories aren't counted, Slycerak and the other Nomadic Mechtogan (excluding Coredegon) technically only won a single battle against the Battle Brawlers by themselves.
