Master Wu's Academy

''Darkley's Boarding School for Bad Boys is a school in which kids are taught to be evil. The school was later renamed Darkley's Boarding School for Great Children in Double Trouble.''

Appearances
When the ninja confronted Lloyd for the first time, they mention him attending this school. When Lloyd first meets Pythor, Pythor questions why he ran away from the boarding school, in which Lloyd tells him that he was actually kicked out for "Lacking the immoral ambition of becoming one of tomorrow's mastermind." Pythor deceptively tells Lloyd that he never should have intended to go to that school in the first place, and they should seek out vengeance instead.

In Double Trouble, the ninja get a letter that since their last visit to the school made them turn good, and that Lloyd was invited to get an honorary degree. But really, Gene, Brad Tudabone and the other kids at the school were just planning a trap for them, to try to turn Lloyd evil again. When the Bizarro Ninja arrived to the school, at first the evil students wanted to help them, but when they decided to team with Lloyd and help the ninja defeat their evil counterparts, they helped them by disguising as the Ninja to confuse the Bizarro Ninja so they can be defeated.

Staff
Nuckal and Kruncha are seen as supply the faculty during Lloyd's attack. In the online video game, some skeletons were the new staff. Later, when the ninja return to the school in Double Trouble, the staff is replaced with teachers meant to teach well.
