The Beast Within

During the Titans fight with a new villain named Adonis at a lab, Beast Boy gets covered in mysterious chemicals, which has drastic side effects on him, causing the Titans to become worried. He starts to act strange and temperamental. When the Titans tell him to leave because of his bad attitude, he gets angry and, against his will, transforms into a new much stronger and more powerful werewolf-like animal form and apparently kidnaps and injures Raven. But there is more to this incident than the Titans would have suspected.
