Melvin (voiced by Russi Taylor) is the oldest and the leader of a young trio of sibling pre-adolescent super heroes in Teen Titans. She is also considered an Honorary Titan.
Melvin is capable of manifesting her imagination. She can theoretically use this ability to animate inanimate objects or even create new objects from thin air. However, her current skill level has limited her to being able to summon a giant stuffed teddy bear named Bobby. Bobby has enhanced strength and durability, as well as being able to turn himself invisible.
