Zabu

Zabu is a saber-toothed tiger native to the Savage Land, the hidden prehistoric jungle beneath Antarctica. He forged an unbreakable bond with the young Kevin Plunder—who would become Ka-Zar—and the two have been inseparable companions ever since, developing a unique partnership in battle.

Few Marvel characters can claim a Silver Age debut alongside Stan Lee and Jack Kirby and nearly six decades of continued appearances — but Zabu is no ordinary figure. Born onto the page in The X-Men #10 in 1965, this beloved Marvel mainstay has gone on to become most closely associated with the pages of Ka-Zar and Astonishing Tales, building a remarkable 179-issue presence that includes nine collector-recognized key issues. Along the way, Zabu has shared adventures with some of the biggest names in the Marvel Universe — Spider-Man, Captain America, and Cyclops among them — while maintaining a loyal X-Men team affiliation that ties them back to those earliest, era-defining days. For collectors who love discovering the quiet legends woven through Marvel's tapestry, Zabu is exactly the kind of enduring, richly storied character worth seeking out.
