"Nerd Hulk" is a clone created by Tony Stark's older brother Gregory from Banner's stem cells. He has retained Banner's Hyper-Intellect as well as the monster's brute strength. Captain America proved this to be a severe disadvantage as it took away the rage that gave Bruce Banner his boundless strength and unpredictability, allowing Rogers to best Hulk in combat with relative ease. Hulk later joined the Avengers in confronting the Red Skull in Alaska. "Nerd Hulk" found himself completely terrified of the Cosmic Cube-wielding Red Skull. However, the Black Widow (Monica Chang) forced him to confront the Red Skull head on, and he at first appeared to be successful in crushing the Cosmic Cube. This was quickly revealed to be an illusion created by the Red Skull, who then blasted the Hulk away, sending him flying into the sky. After a team of Avengers are sent to protect a potential target of Ghost Rider they begin to suspect he is not a mutant as they once believed. In order to learn more about their new target Nerd Hulk and Monica Chang question a caged man in a Spider-Man costume they refer to as "Spider". He reveals the origin of Ghost Rider and informs him the Rider's next target is the man that sent the kill order, the Vice-President. Since he hates the code name "Nerd Hulk," he decides to change it to simply "Banner," and since he became a full staff member. In "Ultimate Comics Avengers 3", he becomes a vampire thanks to the leader Marcus. The Hulk clone later kills Perun, but Captain America takes his hammer and teleports all the vampires, Avengers, (and the Triskelion) to the Middle East. As all the vampires die in the heat of the Sun, Blade impales Marcus, killing him, and Cap takes Perun's hammer and beheads the vampiric Hulk clone.
