Krux

Krux is a legendary Dark Spectrobe Master (almost said portal master lol), leader of the Krawl, Supreme High Krawl, and nemesis of Rallen.
Originally from the Kaio System, he spilled a strange chemical onto himself, causing him to be corrupted by the very things he was trying to destroy.
He went mad with power, and decided to instead harness the Krawl as a power source. He is a mad scientist who used to be the best Spectrobe Master ever, but was later assumed dead. Twice. And a third time.
Nobody really likes him. It's the main reason Maja went against him, along with the fact that HE WAS TRYING TO KILL HER.
