Why isn't Ubisoft able to decide on whether Rayman is the only member of his species or not?

[Haruka]

I can't claim complete credit for the idea, it's one that I adapted from someone else (my brain is thinking Haruka but this is a long time ago so I can't say for certain).

It was actually Spiraldoor's headcanon, in which I still feel it's the most believable theory to describe about the type of universe in constant transformation that Rayman belongs to.
