- "My shoulders bear the weight of all that Meca One has done. All that I can do now is try to prevent him from achieving his dark goals."
- ―Sensei Keiken
Before the first rebellion, he was one of the lead designers of the mining robots that later malfunctioned, becoming the Devastators.
He has long grey hair and wears a mainly white uniform. He has a double sided head, one which bears an angry battle face, the other bearing a casual look.
- He is similar to Sensei Wu from Ninjago.
- He uses the same hairpiece as Lurtz and the Highland Battler, but in light grey.
