Nuklo

Nuklo is the radioactive son of Golden Age heroes Miss America and the Whizzer, born with uncontrollable atomic energy that made him extraordinarily dangerous. Trapped in a containment unit for years, he eventually encountered the Avengers when his destructive power could no longer be contained.

Bursting onto the Bronze Age scene in The Avengers Annual #6 (1976), Nuklo is a Marvel creation born from the imaginative pairing of writer Gerry Conway and the legendary George Pérez — a debut pedigree that alone makes this character worth seeking out. Over a surprisingly long publishing footprint stretching across 43 years, Nuklo has kept remarkable company, sharing pages with heavyweights like Captain America and The Thing across titles including Marvel Two-in-One and Avengers: The Private War of Dr. Doom. With appearances catalogued under Marvel UK and at least one collector-recognized key issue to their name, Nuklo is the kind of deep-cut Bronze Age figure that rewards the curious fan willing to dig past the marquee names — a testament to how richly populated Marvel's universe truly was in that era.
