Viper City(バイパー, Baipaa?)' is a location in Final Fantasy Legend III. Viper City is a futuristic city, and it has its own transport system. At the Rebel Headquarters, talking to Dr. Belski will fully restore the party's HP/MP for free. The Berth Unit can be found in one of the four chest on the right-side of the headquarters.
Dion wants Arthur's help in defeating Maitreya up in Floatland. Dion also mention that Sol and Faye were both taken to Pureland, and Borgan went after them in the Talon2. The party must follow them with Talon, but Maitreya has the X-Plane unit needed to warp to Pureland. Dion mentions that Dr. Pulcer has a plan, and he's in the Undersea Shelter at the bottom of the northern sea just north of Viper City.
Once the Talon is freed, Arthur goes back to Viper City and brings the injured Dion to Dr. Belski who fixes him up. Both Arthur and Dion want to go to Pureland, but Dion warns Arthur that the only way back is through Dr. Quacer. Arthur still agrees to accompany Dion, and off they go.
