Ultimo

Ultimo is a massive alien robot of unknown origin, first discovered by the Mandarin and unleashed as a weapon of destruction against Iron Man. Nearly indestructible and towering in scale, it exists solely to devastate, making it one of Iron Man's most physically imposing enemies.

Unleashed in the pages of Tales of Suspense #78 back in 1966, Ultimo is a Silver Age Marvel menace conjured by the legendary duo of Stan Lee and Jack Kirby — and that pedigree alone makes this character worth seeking out. Over a remarkable publishing span stretching more than five decades, Ultimo has repeatedly crossed paths with the likes of Tony Stark, Iron Man, and War Machine, cementing a place in Marvel's armored corner of the universe. Most at home in the pages of War Machine and Iron Man, this is the kind of imposing, enduring presence that keeps Marvel's mightiest heroes on their toes — a testament to how a single Kirby-Lee creation can echo through the decades.
