Beast boy

This is beast boys origin story my way.
We'll he got his power from cyborg one day beast boy was walking in the park and bumped into cyborg beast boy said that he wanted to join the teen titans then cyborg said that they were holding try outs so beast boy went and robin said what is your power. And beast boy said I can turn into a t-Rex so beast boy did and robin said next after all of the try outs cyborg said hey man it's not your fault and beast boy said I know it just I can turn into more than just one animal I know I can. So they got training and beast boy could soon turn into anything so they held more try outs and beast boy still got rejected but then robin noticed that it was a bad guy so did beast boy robin attacked with his staff and beast boy turned into a giant killa pray mantis and killed the bad guy with his giant claws of awsome ness and that's how beast boy came to be from my side of the story.
