From Bulbapedia, the community-driven Pokémon encyclopedia.
The Orange Crew (Japanese: サザンクロス Southern Cross) is the common term for the Gym Leaders from the islands of the Orange Archipelago. Trainers can't compete in the Orange League until they defeat all the Gym Leaders in the Orange Crew.
The Japanese title, Southern Cross, is a reference to the real Southern Cross constellation that marks the southern sky. It consists of four main stars in a kite shape and a smaller one near the middle. It is often used as a symbol for real countries in the southern hemisphere, such as Australia and Brazil, and also the Orange Archipelago, which is located south of the Kanto region. The locations of the four Orange League Gyms correspond with the main stars in the Southern Cross, with Pummelo Island near the center.
