During a mission to rescue Cream the Rabbit and Cheese the Chao from Dr. Eggman's headquarters, Sonic and his friends are caught in an explosion that transports them to what seems to be another dimension. Sonic's life is eventually saved from drowning by a twelve year old boy named Christopher Thorndyke. Chris lives in a mansion owned by his two celebrity parents with his inventor grandfather. Chris aids Sonic in locating his friends, and it is not long before Dr. Eggman reappears. Sonic and Eggman race to collect all the Chaos Emeralds in the first 26 episodes and eventually, all of the Chaos Emeralds are retrieved and Chaos Control warped parts of their home to Earth (like Angel Island). The rest of the season features plots based on the Sonic games. In the end, Chris' grandfather invents a portal to send Sonic and everything else from his world. Before he leaves, Chris kidnaps him because he does not want Sonic to abandon him like his parents did. Eventually, Chris comes to terms with his feelings and Sonic returns to his own dimension.
It has been years since Sonic and friends returned to their dimension. Chris is now eighteen and has been working on repairing his grandfather's dimensional portal. A plant being named Cosmo arrives on Sonic's planet, looking for the one who can wield the powers of the Chaos Emeralds. Sonic, having been nearly defeated by a new enemy called Dark Oak, scatters the Chaos Emeralds across the galaxy to prevent Dark Oak from using their power. When Chris uses the portal, he suddenly finds himself in Sonic's world. His age has reversed back to the age when he met Sonic. However, Chris still has all his memories of the years since. To Sonic, only six months had passed. During their reunion, Dark Oak and his Metarex army (similar to the Black Arms from the Sonic games) attack steal the "Planet Egg" from Sonic's planet. Without the Egg, all the plants on the planet wither. Once again, Sonic and friends venture into space to retrieve the Chaos Emeralds. After many run-ins with Dr. Eggman and the pursuing Metarex, Cosmo is eventually unveiled as an unwilling spy for the Metarex, who are part of the same race of anthropomorphic plants that Cosmo from. When the Metarex enact a plan that could destroy the universe, Cosmo sacrifices herself with the help of Super Sonic and Super Shadow, and her essence is manifested in the form of a seed. With Metarex destroyed, Eggman helps Chris to be sent back home. Soon thereafter, Dr. Eggman revives his previous rivalry with Sonic, albeit a light-hearted one.
Max Taylor is the son of paleontologist Dr. Spike Taylor. After falling out of bed early in the morning and seeing a meteor falling in the sky, Max sets out into a forest where it crashes with his friends Rex Owen and Zoe Drake. They find a lightning, wind and grass stone. Chomp is accidentally activated when Max rubs the card on the stone. The D-Team meet their new enemies in the Alpha Gang when they come to catch it. The result was that the D-Team and Alpha Gang often clashed for possession of dinosaurs that are activated. In the finale, the Alpha Gang's Seth turns on his comrades with his Black Tyrannosaurus, which is ultimately defeated thanks to Rex's true parents. Seth attempts to bring Chomp back to the past, which fails, and Seth is sent into the past alone. The D-Team surrender their dinosaurs to Rex's parents, with many tears.
In the second series, the Alpha Gang and the Owens return. While the parents are talking, they are kidnapped by Gunenco, a member of the Zanjark Space Aliens. This causes the Alpha Gang and D-Team to join forces against the Zanjark Space Aliens in their plot to obtain the Cosmos Stones. Seth later returns as an ally to the Zanjark space aliens. Jark, the leader of the Zanjark, provides the dinosaur cards. However in episode 75, Seth seems to become a traitor to Zanjark as he appeals to the D-Team for help, saying that they forced him to help them. However, it was really a trick to get the two Cosmos Stones in D-Team's control, despite the fact that he attacks and defeats the Zanjark two episodes later. Kodai Ouja Kyouryuu King: Pterosaur Legends ended in Japan on August 31, 2008.
