Lord Garmadon is the "Worst Guy Ever" and the main antagonist of Winnie the Pooh Goes to Ninjago: Masters of Spinjitzu (Full Movie) and the 2017 film Pooh and Ronald McDonald's Adventures of The Lego Ninjago Movie. He is the brother of Master Wu, Lloyd's father, and Koko's ex-husband. He has also appeared on Lego Ninjago: Masters of Spinjitzu.
- Garmadon will make his first guest appearance in a Winnie the Pooh crossover in the sixth season from Pooh's Adventures of Once Upon a Time, in which he will arrive from The Land of Untold Stories. However, that will be the only chapter in the Winnie the Pooh/Once Upon a Time saga he will appear in, due to Pooh's Adventures of Once Upon a Time 2.0 taking place after the events of Winnie the Pooh and Ronald McDonald Go to Ninjago: Masters of Spinjitzu (TV series) (in which he dies at the end of the fifth season).
