Max Taylor is the son of paleontologist Dr. Spike Taylor. One morning, Max fell off the bed and witnessed a meteor fall from the sky. Then, he went to the forest where the meteor fell with Rex Irving and Zoe Drake. They discovered a flash of lightning, wind, and grass stones. When Max rubbed the card against the stone, Chomp was unexpectedly activated. When Team D comes to capture the Alpha Gang, they will encounter new enemies in the Alpha Gang. As a result, Team D and the Alpha Gang often clashed over having activated dinosaurs. In the finale, Seth of the Alpha Gang betrayed his comrades with his Black Tyrannosaurus Rex and was ultimately defeated by Rex's biological parents. Seth tried to make Zhou Pu go back in time, but failed, and Seth was sent alone to the past. Team D handed over their dinosaur to Rex's parents, and they shed a lot of tears. In the second season, the Alpha Gang and the ancients returned. Just as the parents were talking, they were kidnapped by Gavro, a member of the space pirate organization. This led to the Alpha Gang and Team D teaming up to fight against space pirates and conspiring to obtain the Cosmic Stone. Seth later returned as an ally of the Ghost Space Pirates. Spectre, the leader of space pirates, provides dinosaur cards. In episode 75, Seth seems to have become a traitor. He seeks help from the D team, saying they forced him to help them; However, allowing two cosmic stones to control Team D was really a scam, despite the fact that he attacked and defeated his comrades after two episodes. In the end, although Spectral Space Pirates managed to capture all seven cosmic stones, Seth and Pterosaur defeated Black Pterosaur. When Rex, his parents, and the Alpha Gang left, the Phantom Space Pirates were floating around in a pod.
