Captain Ultra

Captain Ultra is a Marvel superhero who possesses a wide array of powers including super-strength, flight, and invulnerability. His one notable weakness is an irrational fear of fire, which has made his crime-fighting career an occasionally comedic affair.

Debuting in the pages of Fantastic Four #177 in 1976, Captain Ultra is a Bronze Age Marvel creation brought to life by the legendary team of Roy Thomas, Mike Friedrich, and George Pérez — a pedigree that alone makes him worth tracking down. Over a surprisingly enduring stretch spanning nearly five decades, this colorful figure has kept remarkable company, sharing adventures with the likes of Spider-Man, Thor, and Captain America, which speaks to his persistent presence across Marvel's ever-expanding universe. He shows up most memorably in G.L.A., She-Hulk, and Marvel Holiday Special — an eclectic mix that hints at a character who fits equally well in offbeat ensemble stories and mainstream Marvel mayhem. With 21 catalogued appearances and two recognized key issues to his name, Captain Ultra is exactly the kind of deep-cut Bronze Age gem that rewards the curious collector willing to dig a little deeper.
