A demonic humanoid white-haired warrior attired in a brown robe and armed with a spear. Drew and Josh broke into the cemetery to steal the Energy Axis from Vexor when he was powering up Shadowborg. Vexor then summoned Detestro the King Warrior to hunt the boys down and retrieve the device. When Drew used the Energy Axis to become his Mega-Blue form for the first time, Detestro was eventually swept back to the comic books by the Thunder Stinger.
Detestro is mentioned by Drew to be from issue #131 of the comic book series.
