Texa

Origin
Texa was a brilliant crime boss who claimed to possess "the greatest brain in the world." She was about 8 feet tall, and was more than happy to participate in a battle (though usually armed with a ray gun). She commanded an army of hooded men, as well as strange winged creatures. Her headquarters was a giant zepplin which could shower the earth with a knockout liquid, and was also armed with powerful magnets and ray guns. Texa was a recurring enemy of The Scarlet Avenger, and she won more often than not. Although her dirgible was eventually destroyed, Texa herself was never captured.
