From Bulbapedia, the community-driven Pokémon encyclopedia.
Gordor (Japanese: ラゴウ Ragō) is the leader of Go-Rock Squad, the criminal team in Fiore. He is first seen in a mission where the player has to escort him out of Lyra Forest. During the mission, he repeatedly yells at a wild Murkrow because he thought it was mocking him, which reveals a little of his personality.
He is later seen testing the Power Styler by capturing an Entei in the Jungle Relic. The player has to then capture Entei to finish the mission.
On the top of Fiore Temple for the final mission, he faces the player with Raikou, Suicune, and Entei one at a time in that order by using the Power Styler to control them. After Suicune and Raikou are successfully captured, Gordor moves on to tell Solana and Lunick about Entei's power, which is when Plusle and Minun destroy the Power Styler and cause Entei to go wild. Entei turns on Gordor, and the player must capture Entei again to help him. During this time, Gordor flees the Temple.
Near the end of the game, it is revealed that Hastings and Gordor went to school together and at one point worked as colleagues. However, Gordor felt that he kept falling in second place behind Hastings all the time, so he broke away and started his own team with the intent of trouncing Hastings. Gordor had a falling-out with Hastings, when Gordor wanted to use the Capture Styler they invented to control wild Pokémon instead of helping them. Gordor is the father of the Go-Rock Quads.
At the end of the Ranger Net mission to recover the Manaphy egg, Gordor returns to stop the last Go-Rock underling and return the player to Professor Hastings.
