First Appearance: Captain America Annual I#4 (November, 1977)

Powers/Abilities: These two beings were actually a single entity whose mind possessed two separate bodies, only one of which he could inhabit and control at a time, although the transition from one body to the other was virtually instantaneous. The greater the distance between the two bodies, the greater difficulty he had transferring his mind between bodies. It was unrevealed whether either form ate or drank, or had other normal human needs.

    One body, the frail and mute Mister One, was a fraction of an inch tall; this body was usually immobile because he could always use his other larger body for movement. He could communicate telepathically, but otherwise possessed no known abilities other than those inherent to his tiny size.

    The other body, Mister Two, was approximately eight feet tall and possessed superhuman strength (Class 25?) and durability, though it could be completely incapacitated by electrical shock. This body could react to stress by generating defenses, though the defense wasn't always better than the attack itself.

   Both bodies were dependent upon each other for survival. After his larger Mister Two body was seemingly killed, the entity transferred his consciousness for the final time to the tiny and usually immobile Mister One body--realizing that he had only moments to live, he moved about and detonated an explosive mechanism to bring vengeance down upon his killers.

(Guardians of the Galaxy VI#15 (fb) - BTS) - Years ago, the Imperial Guard created a prototype of the Warstar unit, designing Mister One and Mister Two.

(Captain America Annual I#4 (fb) - BTS) - The alien spent his whole life with Mister One doing the thinking, but remaining immobile, while Mister Two saw to his every need; under unrevealed circumstances, the alien and his two bodies somehow arrived on Earth.

(Captain America Annual I#4 (fb) - BTS) - Mister One and Mister Two were found on the side of the highway by a man named Joe Keegan. As they seemed to have no place to go, Keegan brought them to his home, and he made a special place for Mister One inside of his wristwatch, to protect him from harm. Eventually Keegan found that the pair needed more care than he could provide, so he placed a newspaper advertisement "Unique and talented mutant seeks home environment and care from concerned and sensitive persons or agencies equipped to help."

(Captain America Annual I#4) - Both Captain America and Magneto responded to Keegan's ad and arrived at his home at the same time. After seeing Mister One, Magneto decided he would be perfect for his purposes--investigating a tiny spaceship he had found--so he stole Keegan's watch, which contained Mister One. But then Mister Two came rushing in, smashed Magneto's helmet, and hurled him into the distance. Magneto decided to return at a later time, and Captain America took the pair to a SHIELD (Supreme Headquarters International Espionage Law-enforcement Division) medical research facility, where they were studied by Dr. Halsey.

    A week later, Dr. Halsey reported to Captain America on his belief that the pair had a symbiotic relationship, but the alien had grown tired of being cooped up and examined, and Mister Two soon rampaged throughout the facility. Halsey had learned that electrical shock could incapacitate Mister Two, so they easily stopped him, but Captain America decided that they deserved some form of recreation.

(Guardians of the Galaxy VI#15 - BTS) - Magneto found Mister One and Mister Two through a newspaper advert.

(Captain America Annual I#4) - Cap took Mister Two out jogging with him, but they were spotted by Magneto's agent Peeper, and soon Magneto and his new Brotherhood assaulted them. After some futile attacks upon Mister Two, Shocker incapacitated him. Meanwhile, Magneto forced his way into the S.H.I.E.L.D. base and abducted Mister One. After finding Mister Two completely inert, Captain America began to suspect the true nature of the alien.

    Magneto tried to force Mister One to enter the spaceship, threatening him with torture, but Mister One refused (or seemed unable) to move. At the same time, marshaling his efforts, Mister One transferred his mind into Mister Two, who confirmed Captain America's suspicions and led him to Magneto's base. They battled the Brotherhood, but when Burner used his full power against Mister Two, his body responded with a defense mechanism, closing its pores to resist the heat, which apparently caused his body to suffocate (see comments).

    Meanwhile, Magneto had placed Mister One into the ship, in hopes of spurring him to investigate. With his other body apparently dead, Mister One knew he only had a short time before he died, too. Seeking vengeance, the micro-mutant located a lever with a symbolic picture of an explosion above it, correctly reasoned that it was a destruct mechanism, and set it off, seemingly killing himself, Magneto, and the Brotherhood, while the force of the explosion pushed Captain America--via his shield--outside of the chamber.

(Guardians of the Galaxy VI#15 (fb) - BTS) - Mister One and Two transmitted data on their own deaths to the Shi'ar as it happened.

(Guardians of the Galaxy VI#15 - BTS) - Years later, Nova (Richard Rider), acting on the authority of the Pan-Worlds Treaty, confronted Magneto about the deaths of Mister One and Two on S.W.O.R.D.'s space station. The situation was defused by Abigail Brand, who correctly figured out that Nova was acting without the Shi'ar's authorization and only used the deaths of Mister One and Two as an excuse to attack Magneto.

Comments: Created by Jack "King" Kirby.

Who diagnosed Mister Two as having internally suffocated? Captain America...not exactly an expert on abnormal mutant physiology. Everyone else survived the explosion... 

It should be noted that it's unconfirmed whether he was a mutant, as Joe Keegan stated, or a product of a genetic experiment, as Captain America hypothesized. However, the Official Handbook of the Marvel Universe I#8 Appendix listed him as a mutant.

In 2021, it was revealed that Mister One and Two were actually extraterrestrials.
--Markus Raymond

    There is a tiny mutant served by a much larger form in the Acolytes seen in Magneto (1996 series) #1-4. He frequently wore a Magneto-like helmet, and sometimes dwelt within a life-sized Magneto helmet. That guy is named the Orator; neither the previous appearance nor reasons for working with Magneto were mentioned. While I'd like to make them the same, I seriously doubt that Peter Milligan, the writer of that series, ever read Captain America Annual I#4. The appearances don't quite match up, but that never stopped anyone before...
    If that's him, he's in #1 - where he seemed to be a spokesman of the Acolytes, and he is taken hostage by Fabian Cortez in #2, where he seems much bigger, and his life was threatened to test whether Joseph was Magneto or not, but Joseph ordered that he not be harmed.
    Probably not him...oh, well.

Perhaps the people of Centaurius II (see John the Changeling) or the Goloks were the source of the tiny spaceship found by Magneto (I know the people of Centaurius II and the Goloks were a lot smaller than Mister One, but maybe it was a really big spaceship to them); another possibility is that the spaceship was a lost ship from the Microverse.
--John Kaminski

...or that spaceship could have come from the same tiny race as the "Stranger". --Ron Fredricks

Mister One & Mister Two have no known connection to:

Joe Keegan

Keegan was a truck-driver who encountered Mister One and Mister Two while driving along a highway. Since the unusual pair had no place to stay, Keegan brought them back to his suburban home; he made a special place for the tiny Mister One to stay--inside Keegan's own wristwatch, which had holes drilled in the watch-face so the tiny being could breathe.

But Keegan realized the pair needed more care than he could provide, so he placed a classified ad in a newspaper, seeking a home environment for a "unique and talented mutant."

Both Captain America and Magneto responded to the ad at the same time, and the two had a brief battle in Keegan's home. But Mister Two interrupted the struggle and threw Magneto outside.

Keegan then turned over the custody of Mister One and Mister Two to Captain America, who took them to a S.H.I.E.L.D. medical facility.

--Captain America Annual I#4

Dr. Halsey

A physician at a S.H.I.E.L.D. medical research facility, Dr. Halsey (first name unrevealed) seemed to be a specialist in xeno-biology; Captain America brought him the unusual pair of Mister One and Mister Two for study.

Dr. Halsey built a special environmental system for Mister One, which supplied the tiny being with fresh air and proper nutrition; the larger Mister Two was given an adjoining chamber. Halsey theorized that the two beings had a symbiotic relationship.

While Captain America took the restless Mister Two outdoors for some jogging, they were assaulted by Magneto's mutant underlings, and Magneto himself attacked Halsey's lab to abduct Mister One.

With Mister One gone, Dr. Halsey wondered what would happen to Mister Two. When Captain America speculated that Mister One and Mister Two were actually a single entity with two bodies, and thus the same person, Dr. Halsey found Cap's assumption to be unbelievable.

--Captain America Annual I#4


A miniature extraterrestrial spacecraft of unrevealed origin (see comments), it had been found by Magneto, and the mutant master of magnetism was determined to learn its secrets.

Magneto abducted Mister One and lowered him into the spacecraft, so that the tiny being could examine the alien vessel for him.

But when Mister One sensed that Mister Two (his giant other-self) was dead, he realized that he wouldn't have long to live, so he sought a way to bring vengeance upon his killers; the tiny being found the spaceship's destruct mechanism and activated it.

Moments later, the spaceship began to glow, then it erupted in a powerful explosion--Mister One was killed, although Magneto and his underlings survived and escaped.
