Tentakill is the Omnitrix’s DNA sample of a Chimera Sui Generis from the planet Murray.

Height - 12 Ft Body - Humanoid

Tentacle Shapeshifting - Tentakill has shapeshifting arms that could change into a bunch of extremely powerful tentacles, retaining equal strength to his arms as a whole. This allows him to grab his opponents, run quickly, and swing great distances.

Enhanced Strength/Durability - Tentakill is incredibly strong, able to lift a building even without unraveling his arms. He can even survive a nuclear explosion at point-blank range and be unharmed by fire.

Underwater Breathing - Due to his squid-like nature, Tentakill can breathe underwater and even swim at great speeds.

Damage Limit - Despite being able to take massive hits, there is a limit to how much Tentakill can withstand. Such as electricity and harsh impacts.
