Mewtwo

Intoduction
Mewtwo was the main antagonist in Season 2 and made a short apearance in Season 1. He is the mastermind behind the Hydra Project and is the most evil Pokemon known to exist.

Season 1
Mewtwo made his first apperance in the end of Season 1 when it was found that he shares a speacial bond with Lucario from Team Fighting and was, in some ways, manipulating him. With that Season 1 ended.

Season 2
In Season 2 Mewtwo  was hunted by a partnership of Spikes and Arrows, Team Snooze Alarm and Team Fighting. Mewtwo was, near the end of the season, found out to be in hiding in the Crystal Cave, there an epic battle occured between Spikes and Mewtwo. In the end, Spikes defeated, more correctly completely obliterated, Mewtwo and the world was safe. But not for a long time. Mewtwo passed over his project to the Pokemon Darkrai, and in a dark cabin the Hydra Project began.



Season 3
In all of Season 3 Mewtwo controlled Lucario via Darkrai, and by controlling Darkrai the Hydra Project continued.

Between the Seasons
Between Season 3 and Season 4 Mewtwo upgraded his plans. He took in Deoxys, the main antagonist of the third Season, which was thought to have been defeated, and healed him, again, via Darkrai. He now used Deoxys to control Lucario, him being a psychic Pokemon. But before Deoxys replace Darkrai, Lucario took advantage of the brief pocket of being uncontrolled and destroyed the cabin in which the Hydra Project was in. Immediately Mewtwo (Darkrai) came to the cabin and carried the Hydra Project to the Crystal Cave. Mewtwo then put Lucario in the position of guarding the cave from intruders.
