I'm not sure if this has to do with lore precisely, but rather continuity. This is just a commonly debated section of the canon that I'd like to get my theory out for:
The André in Rayman 3 is not the same André in Rayman: Hoodlums' Revenge.
Although it has been debated numerous times, I still believe that the final scene from Rayman 3 was a flashback, not a cliffhanger. You can tell because it's made clear that the moons (yeah, why are there two moons?) are in drastically different positions at the start of the game than the end. Therefore, André is still a red lum as of the end of Rayman 3.
But that leads me to Rayman: Hoodlums' Revenge, and yes, I do believe that this game is canon (if Rayman 1 can be explained into continuity, this certainly can). A lot of sources claim that André "returned" in this game and Rayman had to fight him off again. But no- if you pay close attention to the dialogue, it's implied that after André left Globox's stomach, he left behind a piece of himself. This piece of him is not the same André that was currently floating around as a red lum at that time, but rather a divided part of his soul that he left just in case Reflux failed. He somehow called back the black lums (magic damn you) and the hoodlums returned to resurrect Reflux using plumjuice. Rayman defeated Reflux for the sixth time, André's soul was cast out of Globox, and they carried on with their lives.
So while it is unclear as to what exactly happened to Mister Dark and Razorbeard, I'm fairly certain that André is still a nonvocal, innocent red lum floating around in the Fairy Council.
