Michiko Musashi

Debuting in the pages of Marvel Swimsuit Special #2 in 1993, Michiko Musashi is a Copper/Modern Age Marvel creation brought to life by Manny Galan, and she's carved out a quietly fascinating corner of the Marvel Universe across more than three decades. With 33 catalog appearances spanning titles like New Warriors, Marvel Comics Presents, and House of M: Avengers, she's a character whose longevity speaks for itself — turning up alongside the likes of Spider-Man, Richard Rider, and Speedball in some genuinely compelling company. That at least one of her appearances carries key-issue status makes her worth a second look for any serious collector, and her staying power from the early '90s all the way through 2024 is a testament to her enduring place in Marvel's tapestry. If you haven't tracked down her appearances yet, this is a deep-cut discovery waiting to happen.
