From Bulbapedia, the community-driven Pokémon encyclopedia.
The Drowsy Guy is a character appearing in the Pokémon Ranger series. He has two Drowzee which help him with his job. He is known as the Drowzee Man in Pokémon Ranger.
In Pokémon Ranger and Pokémon Ranger: Shadows of Almia, he allows the player to experience once again their most memorable capture. When he does this, he chants a spell while moving his arms around with his Drowzee.
In the first game, he is found in Fiore Temple just before the screen where Gordor or Rayquaza can be fought. He allows the player to fight the legendary Pokémon Raikou, Suicune and Entei once again. However, he only allows players to bring three friend Pokémon instead of the full seven.
In the second game, he can be found at the top of Altru Tower, just in front of the Luminous Crystal. Speaking to him allows the player to rebattle Darkrai and this time, players are allowed to bring as many friend Pokémon as possible.
In Pokémon Ranger: Guardian Signs, the Drowsy Guy also appears, but this time he allows the player to re-watch the game's end credits. The role of rebattling the final bosses is instead given to Nema's machine.
- Though he was clearly created to supply a logical reason why the player should be able to battle the final boss once again, in the core series, the player has the ability to defeat the Elite Four countless times even though they have already become the Champion, with no characters referencing or implying otherwise.
