Kangaroo

Leaping onto the scene in 1997's The Spectacular Spider-Man #242 — courtesy of J. M. DeMatteis and Luke Ross — Kangaroo is a Marvel character who made their mark in the gritty, street-level corners of the universe, sharing pages with heavy hitters like Spider-Man, Kraven the Hunter, and Maxwell Markham. With appearances stretching across nearly three decades and titles as varied as Punisher War Journal and Daughters of the Dragon, this is a character who has quietly threaded through some of Marvel's most action-packed corners. Fifteen catalog appearances may sound modest, but a presence that endures from the late '90s all the way to 2026 speaks to a stubborn staying power worth a second look.
