By Zack Quaintance — “What in the world is going on at the abandoned X-Mansion?” It’s a line of (on the nose) dialogue that gets delivered on the second page of Giant-Size X-Men: Nightcrawler #1, and it’s also this book’s pitch/concept/mission statement. You know what? It’s also an effective one, one of those superhero comics ideas that make you immediately wonder why you hadn’t already been wondering about what was going on at the X-Mansion now that all the mutants were on an island.
