Axel WM Gs
Axel will knock Aerith up.There is absolutely no reason to think this other than the number of hilarious situations this could involve, starting with everyone else's reactions. Plus it looks like Axel actually kind of does love Aerith, so he might turn into a twisted version of a Papa Wolf...not to mention what the kid might be...
In the Alternate History, Axel is actually peaceful.Check this comic. Notice anything? At least half the people in the background were people murdered by Axel in the proper timeline. Their being alive now could mean that Xemnas's manipulations have made Axel non-homicidal, almost pacifistic...just as planned.
Axel shot JFKWell, he already knocked off Kurt Cobain and Sonny Bono and turned Ronald Reagan into the Hulk. Eventually it has to escalate to this point.
When the series ends, Axel will burn another orphanage down.Come on, who can resist the Book Ends?
Riku WM Gs
Riku is Axel and Aerith's kid from the future.Why not? Time travel's already in play. And the irony of a murderer and a psychobitch having an emo kid for a son would be hilarious. Plus, given that they'd be Abusive Parents before they knew and probably worse after they find out, either Riku would succeed in killing himself, or takes a level in badass, and (for the hell of bringing his name up) becomes Sephiroth.
Riku is playing The Reaper's Game!Red XII has fullfilled his promise to eat Riku's parents. That means that Riku no longer exists eg. dead. This explains the sudden use of TWEWY backgrounds, and the appearence of Axel's murder victims in the background. As I stated above Xion will get involved, fighting for existence with Riku as her partner. Oh.. a Kairi will show up as a reaper.
Riku can remember the "real" past because he isnīt human anymore.Because of the maaaaaaaaaaany surgeries Zexion performed on him, his body (including his brain) consists to 99% of straws, hotpockets and other makeshift organs. Therefore he is some kind of "Miscellaneous-Golem" and not affected by the changes in world history, because his conscience is different from other humanīs.
Larxene WM Gs
Metalocalypse alternate universe.
Alternately, they take place in the same universe and Larxene is one of Skwisgaar's many children.Well, there is the blond hair...plus, if the 'Skwisgaar is the son of a god' WMG is true, it's quite possible that that is where Larxene's lightning powers come from, especially if Skwisgaar's father turns out to be Thor.
Kairi WM Gs
Kairi won't come back to life. She'll become a werepire.Or a Reaper, It depends on whether or not they use The World Ends with You plot points rather than just the characters. The both are technically dead so it's a case of Exact Words.
Kairi will come back to life/become a ghost/zombie/what have you...and kill Axel for killing her.
If Axel and Darth Maul fused, they'd turn into Theodore Roosevelt.Cause he's the only thing more badass than Andrew Jackson. Also, he totally used the Force. I don't care what you say.
In the fanfic Geishas Of Winter, the orphans that Crocodile was raising money for were the orphans who were displaced when Axel burned down the orphanage.
Zexion will eventually become president.President Evil, naturally.
Everything was planned...by Goofy.Of all the important characters in KH, there has yet to be a use for Goofy's sprite at all. And let's face it, he'd be the last person you'd expect to be behind everything.
Xion will get involved in this somehow.With all the reality alterations its possible that she, not, Kairi was sent to the reality TV show mansion. Because she can fight she survived the first season. However her sprite will just be a Kairi Palette Swap. Riku will develop a crush on her due to the fact that her life has been Deus Angst Machina but will break up when she finds out that she's a Male-To-Female transsexual.
We haven't seen the last of Yuna and (girl)Rikku.Red XIII joined the main cast, the others were slaughtered by Axel, but all we know of Yuna and Rikku's fate is they went to dig to the center of the Earth at the Vatican on Darth Maul's suggestion. I wouldn't be surprised to see them pop up again riding an aeon or something, stopping whatever enemy it was this season, then promptly getting eaten by the aeon, who will become the next villain.
Marluxia is either going to die or turn into a monster.Axel, Marluxa, Riku, and Zexion went back in time. Who came back was Emo Mode Riku, Andrew Jackson, Jesus, and an unidentified monster (Heartless). We know about Axel and Zex being able to fuse into Andrew Jackson, and they just recently picked up Jesus to join them, so the only things unexplained is what happened to Marluxia and who the new guys is. One of these things happened:
Roxas will be freed from Sora through means of which that no one, not even the author, will want to go into detail.
If Saix shows up he will surpass Axel and Zexion in jerkassery and will become utterly unlikable.
The Pandora Event was the result of Ansem letting Xemnas out of jail.Remember Darth Maul had him arrested for child molestation and judging from Di Z's words he can't escape on his own and judging by how apparently Di Z warned Ansem and the other reality show hosts about the Pandora Event and how Ansem used the keys(most likely the knowledge of Xemnas's plans) and opened the box(Xemnas jail cell).
