Real Name: Presumably some test subject identification

Identity/Class: Alternate Reality (Earth-85735) murine mutate

    last scene around Washington, DC, USA, Earth-85735

History:

Übermaus-85735-injection

(The One#2 (fb) - BTS) - German Nazi nutritionist Josef Mangele concocted a serum of human pineal gland secretions (see comments) taken from half a million condemned inmates at Auschwitz and Dachau.
Übermaus-85735-one2-larger
(The One#1 (fb) - BTS/ The One#2 (fb)) <1945> - Mangele injected the serum into an ordinary laboratory mouse who subsequently became known to him and his staff as Übermaus.

    The results were astounding, as not only did Übermaus' size and mass double within the first day but his skin proved impenetrable to further injections or any other means of breaching such as bullets or shrapnel.



Übermaus-85735-one1-photo(The One#2 (fb) - BTS) -To sustain the runaway growth in his cell structure, Übermaus was devouring six times his own body weight every day. As he grew larger and larger, this apparently caused problems for Dr. Mangele and his team.

    Given Germany's long fascination with myths and the idea of the super race, Dr. Mangele's research was not lost on the German high command, who, this late in the war were faced with imminent invasion of their homeland.

(The One#2 (fb)) - On January 10, 1945, a high ranking delegation of military and Nazi party officials arrived at Mangele's lab in the city of Zutgart on Germany's north coast to view a demonstration of the Übermaus.

(The One#2 (fb) - BTS) - Somehow, Übermaus' handlers lost control of their prize.

    All of the delegation, along with Dr. Mangele were soon dead, devoured in a horrible feeding frenzy. By the next day, Zutgart and most of its inhabitants had disappeared from the face of the Earth.

(The One#2 (fb) - BTS) - Footage of Zutgart from January 12th showed a swath of destruction, as if a gigantic bulldozer had cut through the heart of the city.

(The One#2 (fb)) - Growing at a fantastic rate and impervious to everything the Germans could throw at him, Übermaus finally slid into the North Sea where he was presumed to have drowned.Übermaus-85735-one6-dc-b&w

(The One#2 (fb) - BTS) - After the Russian army overran Zutgart, Mangele's papers and photo documents were relegated to a Moscow warehouse.

    At some point, Verochtka Pavlova unearthed evidence of Übermaus and pieced together research and documents. She convinced Premier Mikhail Kubalov of the value of the serum, and he obtained the needed pineal gland secretions from their gulag system, ordered the serum to be manufactured, and injected it into a carefully-screened candidate who became known as Comrade Bog (after an ancient word for God). Bog was kept ignorant of the history of the experiment that empowered him, and dietary restrictions were used to prevent him from growing too large and powerful.

(The One#1 - BTS) - Vera Pavlova showed a picture of Übermaus and Mangele in preparation of relating his story.

(The One#2 - BTS) - Vera related Übermaus' origins, and Premier Kubalov detailed how the process was used to empower Comrade Bog.

(The One#6 (fb) - BTS) - Having survived in the Atlantic Ocean for four decades, recent earthquakes drove Übermaus back to land, and he began laying waste in Washington, D.C.Übermaus-85735-one6-dc-color

(The One#6 - BTS) - Vera Pavlova reported Übermaus' return as the USSR's saving grace following the defeat of Comrade Bog.

(The One#6) - The POTUS' advisors noted that Soviets must have sent the giant mouse, as who else could have created such a creature (besides the USA, of course).

    With nothing short of a nuclear weapon sufficient to destroy the creature, the POTUS prepared to depart for Camp David and leave his advisors behind to die "heroically." However, as he paused to watch footage of the super-heroic Charles and Amelia's sex, the pair returned, caught him viewing the footage, and they threw him through the satellite that was transmitting the footage.

    The One? informed Charles and Amelia -- apparently the last surviving people on Earth not enslaved by the Other -- that Übermaus would not last long, as he was very old and the chemical process that created him had wreaked havoc on his metabolism. The One advised they just leave Übermaus alone to graze and clean up the mess for them, as he might live another year.

Comments: Created by Rick Veitch

    Übermaus may be my new favorite character. I would love to see him in another story, but as he is creator-owned from from a different reality in the Marvel Megaverse.

    Übermaus' history in The One#2 notes Übermaus to have been empowered by a serum from pineal gland excretions. The pineal gland secretes directly into the bloodstream and does not excrete anything.

    Size and mass of Übermaus

    Half-ass internet research gives me these stats for a mouse's size and weight:

3-4" long, 2-4" long in the tail

1.2-2" at the shoulder
0.4-0.9 oz. in weight

    Übermaus appeared to be as tall at the shoulder as the Washington Monument, which is 555' tall, or 6660 inches tall, which would make him 3330x the size of a mouse 2" tall at the shoulder. The cube of 3330 is 36,926,037,000, so his weight should be that much greater than that same mouse, which would be about 0.9 oz or .056 pounds. So, about 2,077,089,581 pounds, or about 1,038,545 tons...assuming his mass was not greater due to increased density/durability.
    Another image showed him maybe a little taller than the US capitol building, which is 289 feet, which would make him more like 146,000 tons...

    Übermaus should correctly have the unlaut over the "U," but it will create an unreadable character and an error in the profile when I post it, so I have left it out. If someone else wants to edit the profile to reflect that, that is fine by me.

    Josef Mangele was almost certainly inspired by infamous Nazi researcher Josef Mengele.

   This profile was completed 02/25/2025, but its publication was delayed as it was intended for the Appendix 25th anniversary 's celebratory event.

    Thanks to Loki for recommending Übermaus from The One series, and to Loki, David Zuckerman & Mike Castle for most of the clarifications!
