Pokémon world locations

Mirage Island (Japanese: まぼろしじま Phantom Island) is a hard-to-reach location in Hoenn, found on Route 130 in Pokémon Ruby, Sapphire, and Emerald. It can only be visited under highly rare circumstances.

In the core series games

  This section is incomplete.
Please feel free to edit this section to add missing information and complete it.
Reason: Does the personality value of an unhatched egg count for the appearance of the Mirage Island?
If the player catches a wild Pokémon with the required personality value on Route 130, will the Mirage Island appear immediately after the battle?
Alternatively, if the player catches a wild Pokémon with the required personality value on Route 130 but the Mirage Island does not appear after the battle, will the island appear if the player saves and resets the game before leaving the Route 130?

The island is inhabited by wild Wynaut, which range from level 5 to level 50. Most notably, the island also bears a tree where the one and only Liechi Berry in the game can be picked. This is the best Berry for Pokéblocks, and will produce Gold Pokéblocks. It can also be used as a held item in battles, where it will increase a Pokémon's Attack in a pinch.

Every day, a random number between 0 and 65535 is generated by the game. If this number matches the first two bytes of the personality value of any Pokémon in the player's party, then Mirage Island will appear. (Consequently, Mirage Island can be made to disappear and reappear for that day by removing and putting back the matching Pokémon in the party, and Mirage Island will disappear at the end of the day barring the unlikely outcome of two matching numbers being generated in a row.) This makes Mirage Island's appearance even rarer than encountering a Shiny Pokémon, although the probability increases with the number of Pokémon the player has. The odds of a single Pokémon activating Mirage Island is 1/65536; this chance is increased to approximately 1/10923 if the player has a full party, assuming no two Pokémon in the player's party have the same first two bytes in their personality values.

An old man in the southeastern hut in Pacifidlog Town will tell the player whether or not he can see Mirage Island, allowing the player to check if they have a matching Pokémon without having to leave the town. Since Mirage Island's number does not change throughout a given day, it is possible for the player to freely move Pokémon between the boxes and the party while attempting to check if any Pokémon in the party matches the Mirage Island number.

Technical details

Two random bytes ("Mirage Island Value") are generated for the day once after pressing "CONTINUE GAME," and will be used until the in-game clock passes the midnight of the next day to generate a new value. The Mirage Island Value is generated by pseudorandom number generation and relies on the Elapsed-RTC-days since the player set the in-game clock at home to determine the Initial RTC(d/h/m/s) and start to calculate elapsed RTC. The elapsed RTC days have a one-to-one correspondence with the Mirage Island Value which can be sort as a list[1]. For example, if the number of elapsed RTC days is 0, 1, or 7410, Mirage Island Value will be 0x0000.[2]

Meanwhile, a game that has reached the maximum recordable play time (999 hours and 59 minutes) will continue generating the Mirage Island Value, because the elapsed RTC days are still continue accumulating until reaching its upper limit of 65535(0xFFFF).[3] Only if the cartridge's hardware battery has run dry (causing the real-time clock to stop functioning) or an RTC glitch has occurred (such as the Berry glitch or new battery glitch), will the Mirage Island Values stop generating. At that time, the Mirage Island Value will stay at the last generated value.[4]

Theoretically, elapsed RTC days range from 0 to 65535, but due to the hardware RTC range (2000/01/01-2099/12/31), the actual maximum range of elapsed RTC days is 36524, which means the maximum number of possible Mirage Island Values is 36525; removing duplicate values, the final number is 27925. If the player were to catch a wild Pokémon, the odds of this Pokémon's personality value causing Mirage Island to appear would be 27925/65536 (approximately 42.6%). However, the initial RTC set by that player and the Berry glitch in Ruby and Sapphire can affect the number of Mirage Island Values so that the total number can be lower than 27925.

Currently, it is possible to guarantee the appearance of Mirage Island without cheating. This is achieved by the game's inner mechanism and Berry glitch repair tool "rtcread".[5][6][7]

In the anime

Mirage Island in the anime

In Who, What, When, Where, Wynaut?, Ash, his friends, Drew, and Team Rocket landed on Mirage Island after Team Rocket's submarine crashed. May and Drew got separated from the others and ended up nearly drowning when Drew passed out, before being saved by the resident Wynaut population. Team Rocket tried to steal the island's rare Liechi Berries, but were ultimately stopped. The group was eventually shipped off the island by a man named Roderick, who also gave May some Liechi Berries to be used as Pokéblock ingredients.

While the island does appear on maps, the whirlpools around it make it almost impossible to get to or off the island.

According to Juan, Mirage Island is not the actual name of the island, but what people refer to it as.

Ruby & Sapphire arc

In Talk About Timing, Treecko, Wally rescued a man searching for Mirage Island in Pacifidlog Town from being washed away by Kyogre's storm.

In A Royal Rumble with Regirock, Regice and Registeel II, Ruby and Sapphire were washed up on Mirage Island, where they met Juan, Tate, and Liza. Juan explained that the time on the island advances at a different pace than in the outside world, resulting in the two having been unconcious for 21 days. The time on the island does not always travel at a constant speed, and when the time on the island goes normal, one can get on or off the island. While staying on the island, Ruby and Sapphire encountered the Plusle and Minun from the Abandoned Ship again and trained to become better at Double Battles, in order to be ready to face Kyogre and Groudon. After their training was complete, the Gym Leaders awarded Sapphire with the Mind and Rain Badges, before the two Pokédex holders left the island in Rayquaza Redemption II.

While Ruby and Sapphire fought against Kyogre and Groudon, and subsequently Archie and Maxie, Juan, Tate, and Liza observed the events from Mirage Island through Juan's Kingdra's water screen. In It All Ends Now VIII, when Ruby was revealed to be in possession of Celebi, Juan realized that Celebi's presence on the island explained why time had become unstable there when Ruby and Sapphire arrived on and left it.
