Deoxys appears here at level 30 after the Aurora Ticket event. In the 2026 Switch version, the ticket arrives automatically after the Hall of Fame. Only one shot, so save beforehand.
Deoxys
Birth Island Guide
You need the AuroraTicket event item, which was distributed at Nintendo events in 2004-2005. With the ticket, talk to the sailor in Vermilion City to sail there. On the original cartridge this event has long expired. The 2026 Switch re-release may handle distribution differently.
Interact with the black triangle on the island. It shifts position each time you press A. Chase it in the correct pattern until it turns red and triggers the battle. Deoxys is level 30, Psychic-type. It takes Attack Forme in FireRed and Defense Forme in LeafGreen.
Old Rod only catches Magikarp. Good Rod adds Horsea, Poliwag, and Goldeen depending on the area. Super Rod is where the good stuff lives: Gyarados, Seadra, Staryu, Kingler. You get the Old Rod in Vermilion, Good Rod from the Fishing Guru south of Lavender Town, and Super Rod from his brother on Route 12.
If the encounter table shows Surfing or any Rod encounters, yes. Surf itself is HM03, found in the Secret House deep inside the Safari Zone. You also need the Soul Badge from Koga in Fuchsia City to use it outside battle.
