First Appearances: Strange Tales I#103 (December, 1962)

Strange Tales I#103 (fb) - BTS) - In the recent past, Earth-6212, commonly known as the Fifth Dimension (as described by natives of their own realm). (or a large portion of it) was ruled by the tyrannical warlord, Zemu. Zemu sought to invade and takeover the planet Earth. While his army built an arsenal of war-weapons, other soldiers of his guarded the portal between the realms.

(Strange Tales I#103 - BTS) - However, the soldiers efforts to prevent a housing development from building in the area of the portal attracted the attention of the Human Torch, Johnny Storm.

(Strange Tales I#103) - While Storm was initially captured by Zemu's army, he was freed by Valeria, and led a revolt against Zemu. Storm returned to Earth, and Valeria's father, Phineas, was made the new ruler of the Fifth Dimension.

(Fantastic Four I#158-163) - Years later, Phineas fell victim to a plot of the warlord of Polemachus, Arkon. Phineas entered into business with Albert DeVoor, an agent of the Roxxon Oil Company. DeVoor claimed to represent a large corporation called Inter-Politan Thermo-Dynamics Unlimited and arranged to purchase ownership of Phineas' creations in exchange for funding Phineas' experiments.

    DeVoor's plans were temporarily put on hold when Zemu staged a comeback and temporarily overthrew the rule of Phineas. Zemu led an invasion into Attilan on Earth in a plot to force Black Bolt to power his Thunder Horn, a device able to magnify sound hundreds of times over. Zemu's invasion force was overcome with the aid of the Fantastic Four, and Phineas returned to leadership.

    Soon after this, DeVoor, who was secretly working with Arkon, used Phineas' temperature control devices to cause a near-ice age on mainstream Earth, expanding the polar icecaps. At the same time, DeVoor, who pretended to have similar corporations on mainstream Earth (Inter-Locking Technologies) and Earth-A (Inter-Related Technocracies) ran similar plots on those worlds. DeVoor used the Time Machine of the Baxter Building to send a number of menaces, from soldiers of various armies to dinosaurs, to Earth-A. DeVoor also sent the Andrones of Reed Richards Robotics on Earth-A to the Fifth Dimension. Seeing these attacks of themselves, but unaware of the use of their own weapons on the other worlds, a three-way inter-dimensional war erupted. This plot was designed to end in nuclear war on all three worlds, which would then generate sufficient power to maintain light and heat on Arkon's realm, Polemachus.

    Reed Richards of mainstream Earth (Mr. Fantastic) discovered DeVoor's involvement, and the Fantastic Four assisted in stopping the wars. The Human Torch, who had briefly returned to the Fifth Dimension in hopes of starting a romance with Valeria, had been appointed acting commander of Phineas' army, leading the "retaliatory assault" on Earth-A. The Torch learned the truth from his partner, the Thing, and the Reed Richards of Earth-A, and called off the assault.

Comments: Created by Stan Lee, Larry Lieber, and Jack Kirby.

    The Fifth Dimension was confirmed to be alternate Earth-6212 in the Earth-A entry in the Official Handbook of the Marvel Universe A to Z hardcover#3.

    I'm not quite old enough to know for sure, but I believe that in the Sixties, it was a popular theme to extrapolate on three-dimensional reality and have other realms above the 3rd Dimension. That being said, the Fifth Dimension doesn't really have any properties associated with a reality that has five dimensions.

    You'd think Johnny would make a return trip to see Valeria again some day.

    Perhaps the "Fifth Dimension" an alternate Earth that was colonized by the blue-skinned Kree of its universe (which would help to explain the advanced technology).
--John Kaminski
    The Official Handbook of the Marvel Universe A to Z hardcover#14 entry on Zemu noted that the Fifth Diimension had been designated by some sources as an alternate Earth and further speculated: "whose blue-skinned inhabitants may be descended from Kree colonizers or a land-dwelling Homo mermani offshoot."
    It would be interesting if the Fifth Dimensions mentioned in the clarifications turned out to all be the same realm.

Clarifications: The Fifth Dimension has no known connection to the:

Valeria of the 5th Dimension has no connection to:


Phineas is the peace-loving ruler of the Fifth Dimension, and father of Valeria. He is a scientist who specializes in Temperature Control Devices. He convinced Johnny Storm to lead an uprising against Zemu, and assumed leadership after Zemu's defeat. He fell for a plot of Arkon and Albert DeVoor that nearly led to the destruction of his world, as well as Earth and Earth-A. He was temporarily deposed by Zemu, but was last seen again ruling his realm
