Beast Boy

As a child, Garfield Logan contracted a rare illness called Sakutia and was cured by a serum from a green monkey. This serum had the unintended effect of turning his skin and hair green and gave him the ability to change into any animal form.

Originally known as and reusing the alias, Beast Boy, he was adopted by Elasti-Girl and Mento, members of the Doom Patrol. He later joined Titans West, and was part of the New Teen Titans assembled by Raven. Upon joining the latter, took the name Changeling. He remained with various incarnations of the team, forming a close friendship with Cyborg.

He later began using the name Beast Boy again. Following a failed attempt to recreate Titans West as "Titans L.A.," he rejoined the main team.

Whatever team he is part of, he likes to joke around with people and make jokes of the situations the team get themselves into. However, this is only a facade. In reality, Beast Boy has suffered many hardships in his life. Both his real parents passed away, and his foster mother, whom Garfield became very close to, died in battle along with virtually all of the other Doom Patrol members, while Gar was also part of the team. His foster father was driven mad by a helmet he used to fight enemies. He also fell in love with Terra (a member of the Teen Titans) and was heartbroken to discover that she was a traitor working for Deathstroke. Even after her death, he refused to believe for a long time that she was a traitor and blamed Slade for using her, until they eventually sat down and came to an understanding. As a result of all of this, he used his jokes to cover the fact that he was scared of losing anyone else he grew close to. Despite all of his hardships, Garfield was friendly and upbeat.

Shapeshifting Beast Boy has the ability to morph into any animal he knows of. He can change into extinct animals and even animals on different planets. When he changes the changes only take a couple of seconds. It doesn't matter how big or small. He can change from a tick to a T-Rex in seconds. It puts no strain on him to do this. He can stay in an animals form indefinitely. He can take on the shape of animals without limbs as well, such as snakes or worms. Two times he has changed into multiple animals such as a swarm of fireflies and a group of barnacles. When he changes into an animal he gains all of that animals abilities, such as the sonar of a bat, or the strength of a elephant, the speed of a cheetah. Following the reboot, he has gained the ability to take on numerous animals aspects at a time including antenna, a tail, and scales.

Beast Boy has been shown to shape shift into demonic animals when under the influence of Trigon. Beast Boy can also change into a hybrid, a creature that possesses the powers of all animals rolled into one. He can't control this so he doesn't turn into it unless absolutely necessary.

Beast Boy also has the capability to shapeshift into things as small as germs as shown when he acquired this form when he ventured into Cyborg to combat a virus that he caught. He has shown his capability to multiply in this form. Its highly likely he can do the same with swarm creatures such as ants, termites and locusts and behave as one. Quite possibly, Beast boy can use this power on small creatures.

Even while in human form, he is shown to have above average physical abilities such as strength, speed, endurance, etc. This is mostly due to his altered DNA.

In human form he is strong enough to break apart a sea navigation bell with a punch, react quick enough to evade gun and laser fire, and durable enough to take falls of great heights and hits from powerhouses all in human form.

Poisons He can even gain poison-generating abilities from animals, such as the venom of a snake or spider. While in his animal forms he is capable of speech, and he keeps his intelligence and humanity. The only problem is no matter what form he takes, the animals skin and hair color will always be green. This stops him from hiding in plain sight.
