Stormchu Unleashed

Stormchu Unleashed is a Nintendo Switch and PS4 game featuring a new Pikachu evolution called Stormchu who is stronger than Raichu and faster than Pikachu thanks to the Blue Thunderstone.

Prologue
Pikachu is a great ally to his kind yet even kind and protective towards the Pichus until he got into a fight with a Raichu which ended up with him injured. Then after the fight, Pikachu ended up finding a Blue Thunderstone, a mysterious yet powerful version of the regular Thunderstone, after grabbing it, he evolved into not Raichu but a new Pokemon named Stormchu.

Stormchu arrived back to his home only to see his kind being beaten by Raichu while he was in charge. Stormchu challenges him and with one strike from a Thunderbolt that is blue and not yellow, Raichu has fainted after crashing into the tree which the tree almost felt on top of the Pichus in which Stormchu saved them. But in return, he was alienated because of his new look from Pikachu to Stormchu. The Pikachus and the Pichus began throwing rocks at Stormchu and he ran off afterwards.

After that, Stormchu is all alone but then suddenly a Meowth with a cowboy hat and black glasses came up to him and said that they do not know of his true potential as a Stormchu and willing to train him to control the power Stormchu possess.

With training, Stormchu mastered his full potential with not just Thunderbolt but with Electro Ball, Iron Tail, Quick Attack, Volt Tackle, Thunder, Hyper Beam, Electroweb, Mega Punch and Mega Kick, can use Gigavolt Havoc without the use of a Z-Crystal Electrium Z, and has mastered two unique moves, Lightning Cannon which is a stream of blue lightning from his mouth, and Storm Fury which is a temporary boost of electrifying rage.

After his training is complete, Stormchu decided to depart and head out on a adventure only to be captured by Team Rocket. Inside Team Rocket's laboratories, he was held into a machine being experimented on by Dr. Jakob Grand to see the power of a rare Pokemon such as Stormchu is.

When Giovanni visited the labs, he was quite impressed with the newly evolved Pikachu but before he can exploit it, Stormchu escapes the machine he is held in and unleashed his Storm Fury and smashed through the glass head first. Team Rocket locks down all access but Stormchu continues his escape as he fights through Team Rocket and their Pokemon.

After Stormchu escaped the labs, Stormchu realizes he is on a one-chu vendetta against a crime syndicate attempting to capture him and misuse him for their personal gain. He said that Team Rocket will regret attempting to misuse him as he is unleashed.
