Beast Boy (real name Garfield Logan) is a member of the Team. He grew up in Qurac on an animal sanctuary with his mother, Marie Logan. He received a blood transfusion from Miss Martian after being injured in an explosion. Initially his eyes became green, and over time so did his body. His body also acquired the ability to shape-shift from the transfusion.
As a young boy, Garfield was outgoing and energetic, yet also mature enough for an 8-year-old to help his mother to care for animals. He worshipped heroes, and after a blood transfusion from Miss Martian saved his life, he began to consider her his "blood sister".
As Beast Boy, Garfield still evinces a childlike personality. Often when someone explains anything to him or chides him for his behavior, he responds with "Noted". Like Kid Flash, he has taken up the role to collect souvenirs from each mission.
Prior to his transformation, Garfield Logan had a tanned complexion, blue eyes, and messy red hair. Working on the animal sanctuary, he would wear a black t-shirt under a light blue buttoned and collared shirt. He also wore black pants.
After manifesting Miss Martian's shape-shifting abilities, Garfield's skin became a pale green complexion with green eyes and dark green hair. Generally, he takes a simian-like form, during which he has dark green fur and a prehensile monkey tail in proportion to his size. He wears a red and white single piece uniform. This uniform seems to be designed to adjust to fit his shape, much like Miss Martian's, generally shrinking down to a collar when he adopts a fully animal form.
