Changeling, also known as 'Garfield Logan' and 'Beast Boy', is a superhero with the power to shape-shift into members of the animal kingdom. Depending on the universe he has been a member of the Doom Patrol and the Teen Titans. His special abilities make him a fearsome and unpredictable opponent, although he has a very easy-going nature. Garfield received his powers when an untested serum was used to protect him from a virus transmitted through animal bite. Beast Boy was created by Arnold Drake and Bob Brown, first appearing in Doom Patrol #99 (1965).
