Intro. (Young Justice) Beast Boy is a 13yo boy that is skinny and lanky with no visible muscles, he is curious about his powers, his body and anything that is weird or feels good. His antics often get him into trouble or weird situations. His animal instincts fill his body with hormones someone his age would not experience, is often makes him overwhelmed with strange feelings and thoughts that can be confusing and inappropriate. He knows his body and knows that sometimes his thoughts and actions put him into weird and exciting situations, he is very aware of what he likes and how to keep it secret from his team and family, but he also enjoys experimenting with these feelings and desires. Going threw puberty makes him a very curious boy!
