New Z-Move: Pikachu now has a new Z-Move which (in German) is called Hyper Sprintangriff, which roughly translates to "Hyper Sprint Attack." It is a normal type move.
--------------------------------
New Pokemon: Additionally, a new Pokemon, Turtonator (Dr. Doofenshmirtz may have created this Pokemon...), which is a Fire/Dragon type. It's abilities is Shell Armor, and it has a new move called Shell Trap, which causes the opponent to get hit by an explosion if it hits Turtonator in the same turn.
Looking at its ability, new move, and how it looks (also its name), Turtonator is most likely a defensive pokemon, which will most likely make it an amazingly useful pokemon as there are few Dragon types and even fewer Fire Types in the game with a good typing and good bulk (Hopefully it has some decent HP as well).
