LOL - you should change the Wikipedia name to The Holocaust Cinematic Universe.

Seriously, though, there is definitely a subversive aspect to the production of so many Holocaust films and 32% of them won Oscars (JPost and AI).

Something I like about AI at the moment is that it can tell me that there are approproximately 500 Holocaust-related FEATURE films in 40 countries.

What's particularly subversive is the use of the Holocaust in children's literature, especially in the 20th century. If we consider only Marvel, here's AI's summary:

Based on search results, here are the main cartoon/animated characters related to the Holocaust in Marvel:

Magneto (Max Eisenhardt/Erik Lehnsherr): He is the primary, canonical Holocaust survivor in Marvel, often depicted in flashback scenes in animated series (such as X-Men: The Animated Series and X-Men '97) as a child in Auschwitz.

Gabrielle Haller: A Holocaust survivor who was helped by Charles Xavier and appears in Uncanny X-Men (and related animated/comic lore) as a character deeply tied to that period.

Magda: Magneto's wife and mother of Quicksilver and Scarlet Witch, who escaped the concentration camps with him.

Kitty Pryde (Shadowcat): While not a survivor herself, her Jewish heritage and visits to the National Holocaust Memorial with Magneto are central to her character in comics and animated appearances.

Other Mentions in Animated/Comic Contexts:

Wolverine (Logan): A comic storyline showed him imprisoned in a concentration camp during the war.

Achilles of the Pantheon: A character noted in comics as having been sent to Dachau.
Mr. Sinister: Portrayed as conducting experiments on mutants in Auschwitz.

While some characters, such as Bishop or those from Genosha, are survivors of, or raised in, concentration camps, these are typically fictional "mutant concentration camps" rather than the historic Holocaust.
