His main ability is mind control. He can invade people's mind and control their moves. He's able of seeing through someone's eyes and even manipulated someone thoughts. In theory, he's capable of corrupting someone's mind. He knows when someone is lying and can read minds. He's can also command people to talk and even erase their memory. He's even capable to crash someone's mind, leaving him insane. He's also as strong as a bodybuilder.


If a mind is too complex, he gets a headache. He's also not the strongest, fastest or most agile alien in the Ultimatrix.
