Another option is a demon from Azazel's past. This demon could be after Azazel and sees Nightcrawler as a way to get to him. Maybe the demon has a grudge against Azazel and will stop at nothing to destroy him, and by extension, Nightcrawler who is now associated with Azazel.
It could be a powerful mutant who wants to use Nightcrawler's teleportation abilities for his own evil purposes. He might see Nightcrawler as a key to achieving some sort of world - domination plan.
A human anti - mutant organization's leader could be the main antagonist. He might view Nightcrawler and Azazel as a threat to the 'purity' of the human race and would do anything to capture or kill them. This would force Azazel and Nightcrawler to fight not only for their own survival but also for the future of mutants in general.
