Pantha is a cat-like super-hero and a member of the Teen Titans. Originally a normal woman named Rosabelle Mendez, the Wildebeest Society mutated her into a were-beast. With no knowledge of her origins, she used the name X-24 given to her as a test subject.
Much of her career was spent looking for information about her past. When she left the Titans, she formed a family with Red Star as her partner and Baby Wildebeest as her adopted child. During Infinite Crisis, she was murdered by Superboy-Prime. She has also been a member of the Black Lantern Corps.
