El Toro

A bull-strong presence from Marvel's Modern Age, El Toro made their debut in 2005's Official Handbook of the Marvel Universe: Alternate Universes under the eye of the legendary Alex Ross — a fittingly distinctive origin for a character carved out of Marvel's rich alternate-reality mythology. With just six catalog appearances spread across Young Allies, Captain America: Forever Allies, and the All-New Official Handbook, El Toro is a compact but intriguing figure who shares adventures alongside heavy hitters like Captain America, Bucky, Citizen V, and Rikki Barnes. Rare and roster-worthy, this is exactly the kind of deep-cut discovery that reminds collectors why hunting through Marvel's corners is always rewarding.
