However, it's important to remember that:
* Beast Boy's powers are inherent: He has the ability to shapeshift, meaning he can change his appearance and doesn't need a mask to hide his true face.
* He prefers to be seen as himself: Beast Boy is a character who values his true identity and enjoys being open and honest about who he is.
So, in most scenarios, Beast Boy doesn't wear a mask because he doesn't need it. He's confident in his abilities and enjoys being seen for who he truly is.
