Lloyd Garmadon

Lloyd Montgomery Garmadon is an antagonist (later) the main supporting protagonist of the toy franchise "LEGO Ninjago: Masters of Spinjitsu." He is the son of Lord Garmadon. At first he is evil and teams up with Pythor, but the latter betrayed Lloyd onwards. The Ninjago crew later took Lloyd to their ship, where little by little, he started to develop a friendship with the Ninjago ninjas. He became the prophesized Green Ninja and helped the Ninjago ninjas stop Pythor. He later became the Ultimate Ninja in order to stop his father Lord Garmadon (who was posessed by the Overlord) from plunging the world into an eternal darkness. He destroyed the Overlord and managed to snap his father out of his evil control, thus having his family back together.
