Super-powered Pets

• Krypto, the Superdog: Pre-Crisis, Krypto was the El family's pet dog on Krypton, who eventually wound up on Earth and gained superpowers like Superman's. Recent comics have introduced an updated version of Krypto; this version currently lives with Superboy (Kon-El).
• Comet, the Superhorse: Supergirl's flying horse, originally a Centaur, but cursed to live as a full horse. At various times he has had romantic feelings for Supergirl. Post-Crisis, he was given a different, stranger history.
• Streaky the Supercat: Supergirl's normal household cat, accidentally given superpowers by a new type of Kryptonite. Streaky regularly fights alongside Krypto in the animated series Krypto, the Superdog.
• Whizzy: 30th century descendant of Streaky, the Supercat.
