Pokémon: Berserk

The Awakening Phenomenon is a phenomenon we have recently discovered by using the power of the Berserk Gene found from different types of species of Pokémon. It temporarily increases your stats in battle, although the phenomenon still
has a couple of quirks so you may not want to use it all the time, or else your Pokémon may have some… Unfortunate side-effects.
By the way this game does use more mature themes and creepy scenarios.​
