Black Rainbow

Black Rainbow is a Gundam Wing/Pokèmon crossover story written by pokemonsonicgirl123 (or Poke for short) in 2019. The story was written November of 2018 with up to eight chapters done before being uploaded around mid-January of 2019; it was eventually finished in January of 2020 with nineteen chapters plus the epilogue (totaling twenty chapters altogether).
Black Rainbow is fairly unique among other fanfiction stories in that it implements music inserts--songs used to convey a chapter's atmosphere or a character's internal feelings in this story. Poke went as far as to create a playlist for her story, as well as including a "main theme" and "ending theme."
The story is posted onto FanFiction.Net, ArchiveOfOurOwn.org, and Poke's DeviantART page.
== Synopsis ==
Just a few seconds after the falling piece of Libra has been destroyed, an Ultra Wormhole suddenly opens and swallows all the five Gundam pilots and flings them to the Alola region in the Pokemon World, separating each other, and their Gundams, in the process. Heero and Trowa find themselves on Melemele Island, and are found by a female Pokèmon Trainer named Remilia. Deciding to pose as university students from Unova, Remilia helps Heero and Trowa find their friends and Gundams, while at the same time, not reveal their status as Gundam pilots--or the existence of Gundams--to her. Unfortunately for them, two mysterious individuals begin following the group to all of Alola's islands, taking a very dark and personal interest in them, Heero and Duo especially.
== Plot Summary ==
Heero Yuy and Trowa Barton awake near the Ruins of Conflict on Melemele Island in the Alola region. They are found by a girl and her ride Flygon and she introduces herself as Remilia, a Pokèmon Trainer and current (as well as the first) Champion of Alola. Going with her assumption that Heero and Trowa are university students from the Unova region, they decide to find their fellow Gundam pilots and their respective Gundams.
As Heero, Trowa and Remilia travel the islands, they find more of their comrades in separate locations: Quatre Raberba Winner in Melemele Meadow on Route 3, Duo Maxwell in Lush Jungle on Route 5 on Akala Island, and Wufei Chang on Route 11 on Ula'ula Island. Meanwhile, they are followed by two mysterious people named Phyco and Soliera, who claim that Heero and Duo are "two halves of a key" on whatever their goals might be. Phyco and Soliera also attack the Gundam pilots twice with their Ultra Beast Pokèmon; once on Quatre with Soliera's Poipole which ends in a draw with their visors slashed, and again on Duo when they attempt to bring forth "the soul of Necrozma" from within him. However, they are foiled by another Pokèmon Trainer, former Team Skull Admin Plumeria and her Gengar, and they are forced to retreat.
Due to him being held captive and briefly tortured by them, Duo slowly transforms into a black crystal weredragon (the black crystals growing from his body prior) and starts attacking Heero in the hotel Heero, Duo, and the rest of the Gundam pilots are staying at. Luckily, Heero was able to escape by stealing a car and drives towards the outer cape of Malie City in an attempt to shoot and kill him, but Duo--now possessed by the soul of Necrozma--proves to be too fast and too strong even for him, and is nearly killed when Duo punctures his chest with his new sharp crystal claws. Fortunately, Remilia, the Gundam pilots and the police where able to subdue Duo, saving Heero's life, and he was brought to Aether Paradise for an examination.
While Heero is in a coma from Duo's attack, he encounters a young woman in his dream standing at a balcony. The young woman says that she is the light of Necrozma, also known as "the Blinding One," and was worshiped as a god by the ancient Megalopians (an alien species Phyco and Soliera belong to). She reveals that a long time ago, she (the light) and the soul of Necrozma were one, but the ancient Megalopians became greedy for Necrozma's power to the point where they attempted to harness all of its power for they're own. However, an Ultra Wormhole suddenly opened during the process; not only did Necrozma disappear, but also separated itself into the soul and the light. The soul reincarnated into Duo while the light reincarnated into Heero before their births. The woman also reveals that during her time in Heero's body (while he was developing in utero), she had developed a full consciousness of her own, and thus, she has access to Heero's memories and feelings. She also tells Heero to save Alola from Necrozma, and Heero complies.
After picking Heero from the hospital in Malie, Remilia comes up with a plan to lure the now-possessed Duo to the Altar of Light on Poni Island to return him back to normal with the aid of the Moone Pokèmon Lunala. The plan works without a hitch at first, but it falls apart when Duo, now totally feral due to Necrozma's soul fully possessing him and having absorbed some of the light within Heero, fuses with Lunala at the Altar and becomes Dawn Wings Necrozma, with an off-white and naked Duo trapped into black crystal. Remilia and her fellow Pokèmon Trainers fight the now-possessed Lunala, but the latter proves to the too powerful for them, and in seemingly great pain, creates an Ultra Wormhole (while opening several others) to steal all of Alola's light and disappears into the wormhole.
Though the whole team--Remilia especially--is devastated, Hau points out that the Ultra Wormhole is still open. With the group's hope restored, they separate into small groups and go through the wormhole two or three at a time. In Ultra Space, the Gundam pilots and Pokèmon Trainers find their respective Gundams in different places; Wing Gundam Zero in the Ultra Deep Sea, Gundam Heavyarms in Ultra Tent, Sandrock Gundam in the Ultra Desert and Altron Gundam in the Ultra Plant. Upon retrieving their Gundams, they travel through the Ultra Wormhole and arrive at a "boundary line" between a different dimension and Ultra Space. They discover Gundam Deathscythe Hell, but it transforms into what looks like a cross between the Gundam itself, one of Necrozma's forms, and Lunala (named by the author as Necro Gundam Ultra). They also discover that Duo is trapped inside. Phyco and Soliera, having followed them all the way to Poni Island, attempts to interfere, but Guzma, Plumeria, and Hau challenge them to a Pokèmon battle as a distraction. Awhile, the Gundam pilots, Gladion and Remilia (with Hau's Noivern on loan and Silvally) try and rescue Duo. 
Upon retrieving Duo (seemingly dead and covered in a black crystal coating), the rest of the Gundams stand back while Wing Gundam Zero transforms into Rainbow Wing Zero (also named by the author), and does battle with it. Rainbow Wing Zero proves to be of a better advantage over Necro Gundam Ultra, and after weakening the latter severely, Plumeria and Remilia perform the Ghost-type Z-Move "Never-Ending Nightmare" to push Necrozma's soul of of its new vessel. Necrozma's soul would be destroyed with Wing Zero's signature twin buster rifle. Light beams suddenly erupt from Rainbow Wing Zero's chest to restore Alola's light stolen by Necrozma, with Heero falling unconscious briefly after the fact.
The whole group goes back to the Altar of Light on Poni with Lunala's help, and Remilia restores Duo back to life with a Z-Crystal Lunala created with the last of its free will containing Duo's life force. They all leave their Gundams in the Vast Poni Canyon and head to Aether Paradise for some rest.
Remilia and the Gundam pilots leave for Poni the next day, so that Remilia can see them off for their home dimension and timeline. Upon exchanging some souvenirs to remember their adventure, the Gundam pilots say goodbye to Remilia and they leave through the Ultra Wormhole with their Gundams.

== Notes & Trivia ==
* The idea for Black Rainbow came to be due to Poke's musings on how the Ultra Wormholes effect other dimensions. Thus, she watched Gundam Wing for the first time to get a general idea of the characters themselves and create a crossover story with Pokèmon Sun and Pokèmon Moon, with some elements borrowed from Pokèmon Ultra Sun and Pokèmon Ultra Moon. Being a believer in the multiverse theory, Poke believed that Ultra Wormholes don't just exist in the Pokèmon universe, but also in different realities and dimensions, the Gundam multiverse being no exception.
** Additionally, Heero being unusually slightly tender with Duo came to be while Poke was reading Gundam Wing yaoi fanfiction portraying Heero and Duo as a romantic couple (which also prompted her to watch Gundam Wing herself). Thus, she wrote in a little bit of the fanservice for the Heero/Duo fans.
* Throughout the story, there are some partial or even subtle references to various media:
** In Chapter 2, while Duo and Mallow were skinny-dipping in a lake deep in Lush Jungle, they start arguing and trash-talking each other; their dialogue is somewhat similar to Heather and Leshawna's trash-talking from Total Drama Island.
*** In the same chapter, something starts tugging onto Duo's hair, and Duo angrily yells at it for that, and upon realizing that it's an Arbok (essentially a giant cobra), screams and starts running away from it. This is a reference to a scene in one episode of Nanbaka in which an autonomous doll tugs onto Uno's long braid, scaring him in the process.
*** In Chapter 5, Remilia's Primarina's water performance gives a nod to one of the opening scenes in Pokèmon Ranger and the Temple of the Sea in which Lizabeth and her family perform at a town.
*** In Chapter 6, Duo and Remilia's challengers are Ace Trainer Lawrence and Rising Star Juliet, names taken from Friar Lawrence and Juliet Capulet in Shakespeare's play Romeo & Juliet.
**** In the same chapter, Remilia performs the Fighting-type Z-Move All-Out Pummeling in the same manner as Domon Kasshu's Erupting Burning Finger, sans through some dialogue changes.
*** In Chapter 18, the Gundam Pilots and Pokèmon Trainers encounter Gundam Deathscythe Hell transforming while surrounded by wisps of light; a direct reference to either Dusk Mane Necrozma or Dawn Wings Necrozma transforming into Ultra Necrozma.
****In the same chapter, Necro Gundam Ultra lets out a roar intended by Poke to sound similar to Unit 01's roar from the anime Neon Genesis Evangelion.
*** In Chapter 19, Duo being brought back to life and the team looking out to the horizon on the Altar of Light after is a small reference to one of the ending sequences in Atlantis: The Lost Empire where Kida returns from Atlantis's crystal.
* During the journey to retrieve the Gundams, the Gundams featured are the Endless Waltz versions.
*Hikari's physical appearance as described is somewhat similar to Irui Gan Eden's (of the Super Robot Wars series) adult form.
**Additionally, Hikari's outfit as described is of resemblance to Minbari Ambassador Delenn's clothing from Babylon 5 before her transformation.
**Hikari's physical appearance is deliberate on Poke's part, as she wanted her to resemble Relena Peacecraft and Duo Maxwell due to her also shipping Heero/Duo/Relena.
