Captain Ultra first appeared when he attempted to join the Frightful Four. After losing the job because he passed out when the Wizard lit a cigarette in celebration, Captain Ultra disappeared, getting counseling from Doc Samson to conquer his fear of fire. He remained a super-hero for a while, but then quit and became a successful comedian.
When the Super-Human Registration Act went into effect, Captain Ultra registered. Captain Ultra was made the leader of the Nebraska Initiative team. During his time as leader one of his members, Cooper Roth, also known as Paragon killed his teammate, Gadget. As a result, Iron Man wanted to disband this team. Captain Ultra fought Iron Man in order to protect his team.
Captain Ultra's powers were released through hypnosis by an alien, giving him the power of flight, ultra-strength and endurance, durability, and reflexes. He also gained the psionic ability to become intangible at will, see through substances, and the ability to project his breath forward with great concussive force among others. He can apparently tap his 'ultra-potential', enabling him to manifest a wide variety of mental and physical 'ultra-feats'.He also has the "ability" to tell ultra-jokes.
