Digimon Frontier

In the Digital World, five children must stop Cherubimon from annihilating the planet, facing bizarre creatures and their own destinies.

Five children receive strange messages on their cell phones that lead them to a train that takes them to the Digital World, a strange world filled with bizarre creatures called Digimon. These children have been sent there to stop an evil Digimon named Cherubimon from completely annihilating the planet of all its inhabitants. In order to accomplish this, the five children must locate their "spirits", which will evolve them into the Legendary Warrior Digimon. Unfortunately for them Cherubimon has ordered his servants to stop the kids from finishing the mission; eventually the children will have to fight Cherubimon's forces in order to save the planet.
