Citressa is a background character on OK K.O.! Let's Be Heroes. She is the mother of Drupe, debuting in the episode "Parents Day".

Citressa has an orange fruit-like skin because she is an orange and green leaves for her hair. She wears teal eye-shadow, red lipstick, and mascara. She wears a business-like attire consisting of black blazer, white dress shirt, teal dress pants, and gray high heels. She wears a magenta beaded necklace and carries a watermelon purse.

"The result of an experiment to create a citrus fruit with superpowers, Citressa was one of the most popular solo heroes a decade ago. She was so popular that she started her own business empire to capitalize off her image and now runs that."
