Wilhelmina von Kenya

The villain of the Ultima Thule arc (#13, #15-#16): a Black woman obsessed with Aryan/Nazi ideology - a Grace-Jones-meets-Heydrich caricature - and a former seismologist who unearthed a buried Nazi superscience cache in Antarctica. She tortures Matchman, drains his powers with the Stealth Saucer, and dies in its crash, shrieking “I AM THE EMPRESS OF ALL CREATION!” A running joke: she flies into a rage whenever anyone points out that she is a Black woman worshipping Aryan ideals.
