Magneto could be an interesting inclusion. His complex views on mutants and humans can create conflict in the story. He might see the relationship between Nightcrawler and the OC as either a threat or an opportunity, depending on his current goals. Jean Grey is also a good choice. Her powerful telepathic and telekinetic abilities can be a great asset in battles or in helping the OC deal with any mental or emotional turmoil. Plus, her relationship with the other X - Men can add depth to the overall story.
Professor Xavier would be a great addition. His wisdom and leadership can provide guidance to both Nightcrawler and the OC. He can also offer insights into the nature of their relationship and the challenges they might face as a mutant - human (assuming the OC is human) couple. Another good character could be Wolverine. His rough and tough nature can contrast with Nightcrawler's more gentle and spiritual side, and he can act as a protector or a source of tough love for the OC.
Storm would be an excellent character to include. Her control over the weather can add an element of power and drama to the story. She could also be a friend to the OC, helping them understand the world of mutants better. Additionally, Beast could be in the story. His scientific knowledge can be useful in various situations, like if the OC has some sort of unique genetic condition or if they need to figure out a way to combat a new threat. He can also be a bit of a comical relief with his erudite yet endearing personality.
