Reader insert - Turtles meet Titans

(Y/n) is the twin sister of Garfield Logan, or better known as beast boy. They haven't seen in each other in years due to the fact they don't know other is alive. After the incident in Africa that left both with changing powers, (y/n) went to New York and met the turtles and became good friends with them - espically Michelangelo since she is dating him. Master splinter has gone to Japan for a few months so the they have all retreated to April's farm house for some relaxation, what they don't know is that both twins are going to get the shock of their lives.

(I don't own the turtles or the Teen Titans, Nickelodeon and Cartoon Network do)
