Taka is first met at Malchous Forest, where he laments the damages of the PULSE Machine. He elaborates on the PULSE project and its effects on the Pokémon used in it, and claims he'd like to set the Tangrowth free, but has orders to follow-Including eliminating the player.
Taka is encountered again at the Beryl Ward, along with ZEL and a mysterious agent. He acts far more calm about the players interference than his comrades, and happily admits to inviting them there. After Heather's interruption, the agent commands them to team up with ZEL against the player. Upon defeat, Taka decides to escape, inviting ZEL to follow.
