Wonder Dog appeared at Titans Tower one day and was taken in by the team's resident technophiles, Wendy and Marvin. Titans member Miss Martian endeared herself to Wonder Dog by shape-shifting into a canine. She even provided the animal with a green cape. That evening however, Wonder Dog demonstrated his true identity as he transformed into a hideous monster and attacked the siblings, killing Marvin and restricting Wendy to a wheelchair, which led to her becoming Proxy. He was later revealed to be a hellhound owned by Lord Lycus, Ares' son, whom Ares had sent to take the power of Wonder Girl. Wonder Dog was later killed by the Teen Titans.


  • This version of Wonder Dog is a distorted re-imagining of a character first introduced in the 1973 animated television series The Super Friends.
