In the next update Gigantamaxing pokemon and Z-moves should be added. For Gigantamaxing Pokemon, it could be a form of evolution, plus it would be a use for Gigantamax pokemon. For Z Moves, you would need Z Crystals you get from Alola Gyms. There could also be Z rings which would be required to use Z-Moves. Then there could be an extra move button saying the Z-Move name and then you would click the button to use it. It could be disabled after you click the button once in a battle, until it is over. In the next update, there could also be battle screen decorations. That could all be in Pokemon Vortex V6.
