Planet Alcatrand has been identified in the anime, F-Zero: GP Legend. It is the homeworld in which felonies and murderers had been exiled and put into permanent cold sleep. In Episode 2, itt was first pointed out by Jody that surveillance picked up Black Shadow and his Dark Million organization ransacking the prison and awakening Rick's nemesis, Zoda. Later on, Jody herself decided to investigate the devastated facility and find any traces of Zoda, but the place was left abandoned. However, she was soon ambushed by him, as the maniac declared this was his spot to chill out.
While it may be considered to house White Land, some fans had identified Planet White as its home planet. The name was of course a homage to the infamous prison, Alcatran.
