Prime

Prime is a spy sent by the Tentin Force Team to stop Umberto from fulfilling the Tentin Legend. The player first meets Prime in Zubat Cave.

By the time the events of Pokémon: Return to Tentin occur, Prime is confirmed to be deceased.

Prime has an older brother, Allume, who was a member of the Tentin Elite Four.

In Tentin Redux and Return to Tentin
Spoiler warning!

Prime is a man whose mind can be manipulated easily. He also gets in big trouble frequently by rushing into the problems instead of thinking it out first. Prime is also the enemy of all Pokémon Poacher members.

It is revealed in Pokémon: Return to Tentin by Inigo that Prime worked for the Tentin Force Team, and Prime's goal was to spy on Umberto, in order to keep the Tentin Legend. So, this means that Prime was never truly working with the player.

In Tentin Redux, Prime was defeated by Umberto in the Dept. Store Basement, and is impaled by Umberto's Nidoking shortly after, as a show of force as to show the player not to interfere with the Pokémon Poachers anymore.
