The Capture Arena is a location dedicated to helping rangers sharpen their skills in Pokemon Ranger and Pokemon Ranger: Shadows of Almia. The rules there are simple, first go into a room to capture a Pokémon to use for a poke assist. Then go into another room to capture the boss Pokémon. The more rooms you beat the more rooms you unlock. The final bosses in the Capture Arena in both Pokémon Ranger and Pokémon Ranger: Shadows of Almia are Charizard, Salamence and Flygon.
