Ixar's ship


Avengers I#37 (fb)) - "For millennia, a thermonuclear war of cosmic proportions was waged between the Sirians and the inhabitants of a nearby star system. Finally, both worlds used up their enormous supplies of fissionable material...and were reduced to carrying in the deadly power struggle with more basic weapons. Finally, except for the two leaders, all humans on both worlds had perished--for, only an artificial being could hope to survive such prolonged pitched combat. Thus it became Ultroid against Ultroid....And then, a short time ago, came the climactic the Ultroids of our foe penetrated the palace of Ixar and were driven out only after inflicting a heavy toll...However, Ixar was dying...and there remained open to him only one possibility for life." His mind was transferred into computers constructed by his ancestors. "But, when the complex transferal was completed, the immortal mind of Ixar conceived a bold new plan..." They searched the Galaxy, intent on finding a race of humans who possess superhuman abilities, which he could siphon into his Ultroids. "For many of your years, our quest was fruitless! Yet one day, we entered the solar system of a medium range star--and found...your planet Earth!"

(Avengers I#36 (fb)) - Ixar's ship landed in Transia, where he captured, impersonated, and apparently slew the Burgomeister (along the lines of a Burgomaster, the chief magistrate of some towns in Europe). Quicksilver and the Scarlet Witch were in Transia at the time, and investigated the ship. They were both neutralized and captured. Ultrana impersonated the Scarlet Witch and traveled to the USA to bring the Avengers.

(Avengers I#36, 37) - The Avengers and their ally the Black Widow traveled to Transia (Cap suspected as much, but risked it to rescue their fallen comrades). Once in Transia, they were quickly brought to Ixar's lair where he appeared in the form of a massive supercomputer, claimed to be holding the Burgomeister hostage. The Ultroids easily captured the Avengers, except Hawkeye and the Black Widow who were presumably left alone because they possessed no superhuman abilities. That didn't prevent them from freeing the others. Ultimately, Ixar drained the power of all the Ultroids into one massive robot, which attacked and defeated the escaped Avengers. During the battle, Hawkeye realized that the seemingly helpless "burgomeister" was actually Ixar himself. Hoping to end the battle, Hawkeye threatened to fire a lethal arrow at the man, but Ixar remembered that all Avengers have sworn an oath not to kill, making the archer's threat an empty one. However, he hadn't counted on the Black Widow who pointed out she wasn't an Avenger and as such was bound by no such oath. Properly intimidated, Ixar agreed to take his ship and leave Earth in peace. He left to find another planet with superhumans that he could tap.

(Avengers I#37 - BTS) - After Ixar had left, the Avengers explained his disappearance to the people of Transia by claiming their beloved burgomeister had died a hero's death in the recent struggle.

Robotic Ultroids and Ultrana? It's not difficult to see where writer Roy Thomas went for inspiration when he named a certain adamantium clad killer robot Ultron a year and a half later. --- Norvo

The race at war with the Sirians was never identified (other than being described as humans...most likely a humanoid extra-terrestrial race, much like the Sirians themselves. They also had their own version of the Ultroids). They are listed as unrevealed in the Sirians' entry in the OHotMU Deluxe Edition#15 (1986).
In X-Men I#21, Lucifer details the defeat of the Sirians by Dominus, the planet-conquering weapon of the Quist. The Sirians' entry in the OHotMU also details Lucifer's statement further:
"The Sirians originated on Sirus III, but had a colony on Sirus IV. The Sirians of Sirius III were destroyed in an interstellar war with an unrevealed alien race. The Sirians of the colony world were conquered by the Quists. The one known Sirian to escape domination was the renegade Ixar, who came to Earth with the intent of conquest and was repulsed by the Avengers..."
In X-Men Index#1 (1994), detailing X-Men I#21, and Avengers Index#1 (1994), detailing Avengers I#37, are both consistent with the OHotMU entry.
Ultrana's story doesn't quite jibe with this info, but since the information regarding Ixar's mind-transfer into the computer was false...or was it?...who knows? I guess the OHotMU would be a more reliable source than either of two aliens out to conquer Earth, but it's been wrong before, too.

Ixar has an entry in Marvel Legacy: The 1960s Handbook. Hans Geldoff's name was revealed in Ixar's entry in OHOTMU A-Z HC#5.

Ixar has no known connections to

The Ultroids have no known connections to

Ultrana has no known connections to



The Ultroids are "far more than androids--They are the Ultroids--the strongest and most tireless of the many weapons of Ixar." They possess some degree of superhuman strength (enhanced human) and durability. They are intelligent, but primarily follow the orders of Ultrana, or Ixar himself. In addition, the machines of Ixar can analyze and duplicate the energies of super-powered beings, and transfer that energy into each of the Ultroids. They never demonstrated any more than an occasional burst of speed after adapting the powers of Quicksilver and the Scarlet Witch, though. Ixar converted all of the Ultroids into energy and absorbed them into his robot. He presumably can make more.

--Avengers I#36, Avengers I#37

Ultrana fullbody Ultrana close-up


Ultrana is a female Ultroid who served as Ixar's second in command. Though she prefered to shy away from active combat, she seemed much more intelligent than the other Ultroids. In addition, she demonstrated the ability to duplicate the form of others. Ultrana impersonated the Scarlet Witch in a succesful attempt to draw the Avengers to Transia where Ixar had a trap waiting for them. She was convincing enough to fool them, until she slipped upand made a comment about possessing a radar-like ESP sense, which Wanda clearly never possessed. Ixar's guardian robot also claimed Ultrana's lifeforce, though it seems likely she could be recreated.

Ixar's robot

Ixar's robot

Ixar's robot is a giant Ultroid, powered by the sum total of the energy of all of the other Ultroids. It stands over 15' tall and possesses at least Class 25 strength, and a high degree of durability. It could release powerful force blasts and bursts of electricity. It proved vulnerable to the Scarlet Witch's hex powers which targeted its delicate control mechanisms. It also has the capacity for rapid self-repair, enabling it to recover in minutes. It's primary weakness is Ixar himself, who controls the robot mentally, but lacks any other personal defenses.

--Avengers I#37

Hans Geldoff

Hans Geldoff

Geldoff functioned as burgomeister of a town in Transia where Ixar's space ship landed. At first, he tried to reason with and aid Ixar, but he soon found the Sirian had plans for him. Ixar slew Geldoff and took his place, mimicking his form and pretending he was the one, true Burgomeister. After the Avengers discovered Ixar's deceit and sent the Sirian packing, they decided to tell the local Transians that their beloved burgomeister had heroically died in the line of duty.
