Rockstar (ロックスター) is a dinosaur.
Rockstar has a normal dinosaur's body. She has small hands similar to a T-Rex. She has a dark blue colour on the outside skin and has a creamish color on the inside skin. She has red eyes and has sharp jaws. She has two scars on her left eye.
Rockstar made her debut in Episode 32, where Rei Rukh used his Sphere Device to brainwash her. Because of this, when Tobu and Raimon found her, Rockstar began to attack all of them. Tobu found this strange, as she wasn't supposed to use this much energy. He later tried to stop her by using Taiko no Senshi Jaggerwock and saying to her to calm down, but the dinosaur just threw him to the side.
Finally, Tsurugi, Tenma and Taiyou made her come to her senses by using their skills soccer and hitting him with Death Drop. As she was more calm, Tobu asked her what happened and Rockstar replied that she was attacked by someone using a soccer ball much like the one that Tenma was holding, which Shindou quickly related to El Dorado.
Seeing that the dinosaur was exhasted, Kinako asked what was wrong with her. Tobu answered that Rockstar had no much time left, and was going to die soon. Fearing this, Shinsuke asked what they could do to help her, but the Jurassic boy replied that they can't do anything as this was the life normal flow. As Big appeared, Tobu explained that he was Rockstar's son and the only reason to Rockstar to still stay alive. Rockstar later used the last of her energy to protect Raimon, Tobu and Big from Death Horn, dying shortly after that but before dying, she entrusten Big to Tobu.
