Yeah it's a pity that this was cancelled. I can answer your question Flame, sort of. I won't spoil much out of it though. Actually, I cannot give out almost any information at all, because this story was so heavy on the surprises and twists. And would have gotten even more. I love that stuff.
After Aladraina would had imploded and thus exploded, Erstrund's group would basically continue to hunt down the the last remaining Replenloids at other locations, while other characters that were already introduced, but left the scene, such as Dr.Zejaf, would had gotten proper and better character development in new scenarios.
Eventually, the 8 Replenloids would had to be refought again(they got revived), but this time by X most of the time, keeping true to the current era of X, since Axl was missing and Zero was sealed. This would happen on a certain control station in space, but I absolutely cannot tell which other characters other than Erstrund, X and the 8 Replenloids would be present there in this so called final battle. And a huge, huge twist was waiting after those fights, but unfortunately, unless I somehow revive this, that won't be known to the public.
