While I would necessarily call this my headcanon, it's certainly a headcanon-ish idea I've had about the inconsistencies in Rayman's backstory, and the canon in general. I present to you... Reincarnation and incredibly long periods of time! Yaaaay!
Okay, so we start with the first Rayman. My fave. He is either born naturally or created by Betilla the fairy (though her introduction to him in the Pink Plant Woods would suggest the former) and lives out his life among the other limbless, with the events of Rayman 1 and its educational spin-offs included. Then he eventually dies, either in some heroic way or by natural causes, who knows.
Cut to some obscene number of years later, and on the shore of the Glade of Dreams, who should wash up but dear little Rayman the second. Except no-one knows who the heck he is, what the heck he is, or where the heck he came from. Even Rayman himself doesn't realise he's the reincarnation of a hero from far back in history. How exactly he was reincarnated is unknown too. At this point the limbless have either died out, dwindled into obscurity, or live in such isolation that their existence is unknown to anyone else.
Now, as far as Rayman 3 goes, I don't really know if this Rayman would be the same one as in Rayman 2 or another reincarnation. With Murfy and Globox still being around it'd make sense that he's the same one, unless he died and was reincarnated again in Murfy and Globox's lifetime. Someone I chatted to in the IRC (Buildersith if I recall correctly?) also brought up the idea that each globox between each game is actually a descendent of the last, taking his place while Rayman sleeps for decades at a time. Getting back to Rayman, if he was indeed another reincarnation at this point, that could account for his rather noticeable change in appearance (I mean fair enough you don't have to be killed and reborn to change your hair and outfit but still...). This Rayman was purposefully crafted with the intention of reincarnating the previous, and he lives out through the events of Rayman 3 and the Rabbids games, before presumably ending similarly to the first Rayman.
I was going to write the part about Origins/Legends (Basically a long time later Betilla the nymph and her sisters tried to create a warrior but screwed it up and accidentally reincarnated Rayman again) but the more I write, the dumber this all starts to sound. It was falling flat on its face, really. :lol: I suppose it'd do as an AU timeline though?
