Electro Ball inflicts more damage the faster the user is compared to the target. Therefore, the larger the relative difference between the user's and target's Speed stat, the greater the damage. Base power is calculated as follows:
Galvantula forms an orb of yellow and orange electricity with yellow electric sparks around it in front of its mouth. It then fires the orb at the opponent. The orb explodes when it hits the opponent, which leaves behind yellow electric sparks in the dust and smoke.
Pikachu's body becomes surrounded in yellow electricity and multiple yellow sparks come off Pikachu's body. All the electricity then condenses at Pikachu's tail and forms into an orange-yellow orb of electricity with sparks of yellow electricity coming off it. Pikachu then jumps into the air and does a front flip, throwing the orb of electricity at the opponent. Sometimes, Pikachu's body doesn't become surrounded in yellow electricity before using the attack, and sometimes it only forms around the tail instead of the whole body.
Multiple sparks of yellow electricity appear at the end of Emolga's tail and an orange-yellow orb of electrical energy releasing yellow electricity forms from the sparks. Emolga then jumps into the air and flips forward, firing the orb from its tail at the opponent.
