10 He Can Shapeshift Into Any Animal Titans only showed Beast Boy shapeshifting into two animals - into a tiger and a snake. However, this ability of his is much more complex in the comics. In the comic books, the Beast Boy can shapeshift into any animal he chooses.
Powers and abilities. Beast Boy has the ability to morph and transform into any animal that he has seen himself or has seen in an illustration (as is the case when he shapeshifts into an animal such as an extinct dinosaur).
Beast Boy / Changeling (Gar Logan) can most typically shapeshift into any beast, meaning any non-sentient creature in the animal kingdom. As such, no, he couldn't become a sentient force of any kind.

He has changed into multiple animals, such as a swarm of fireflies and a group of barnacles. The only problem is no matter what form he takes, the animal's skin and hair color will always be green. Beast Boy can also change into a hybrid, with all the animals' powers rolled into one.

Lobdell decided that given that Gar has animal powers that his source of power being the Red makes sense, and he's not necessarily wrong.

Beast Boy was bitten by one of the monkeys and contracted a serious illness called Sakutia. To save him, his parents attempted to cure him with a new serum, which bestowed him with his shape-changing abilities. As a side effect, his skin, hair, and eyes turned green.
