As Gigantamax Pikachu, it becomes larger and chubbier. Its tail becomes longer and becomes capable of storing all of the electricity it generates, causing it to glow a bright yellow and enabling it to become as powerful as a lightning strike. Three red clouds float around the tail. Its power is equal to that of a power plant; however, it is difficult to use it in peoples' homes since Pikachu can only remain in its Gigantamax form for a short time.
