Ninjango has been calm for as long as anyone can remember. That should be a glaring sign of something bad coming around the bend. That something bad comes courtesy of Lloyd Garmadon, the son of the supremely baddie Lord Garmadon, in that he has somehow created a new kind of evil. Lloyd wants to follow in his father’s evil footsteps but that has put all of Ninjango in danger.
