Raichu

Red / Blue: Its long tail serves as a ground to protect itself from its own high voltage power.

Yellow +2: When electricity builds up inside its body, it becomes feisty. It also glows in the dark.

Gold: When its electric­ ity builds, its muscles are stimu­ lated, and it be­ comes more aggres­ sive than usual.

Silver / SoulSilver: If the electric pouches in its cheeks become fully charged, both ears will stand straight up.

Crystal: If its electric pouches run empty, it raises its tail to gather electri­ city from the atmosphere.

Ruby: If the electrical sacks become excessively charged, RAICHU plants its tail in the ground and discharges. Scorched patches of ground will be found near this POKéMON's nest.

Sapphire: This POKéMON exudes a weak electrical charge from all over its body that makes it take on a slight glow in darkness. RAICHU searches for electricity by planting its tail in the ground.

Emerald: If it stores too much electricity, its behavior turns aggressive. To avoid this, it occasionally discharges excess energy and calms itself down.

FireRed: Its electric charges can reach even 100,000 volts. Careless contact can cause even an Indian elephant to faint.

LeafGreen / Sword: Its long tail serves as a ground to protect itself from its own high-voltage power.

Diamond: It turns aggressive if it has too much electricity in its body. It discharges power through its tail.

Pearl / Y: It can loose 100,000-volt bursts of electricity, instantly downing foes several times its size.

Platinum +4: Its tail discharges electricity into the ground, protecting it from getting shocked.

HeartGold / X: When its electricity builds, its muscles are stimulated, and it becomes more aggressive than usual.

Omega Ruby: If the electrical sacs become excessively charged, Raichu plants its tail in the ground and discharges. Scorched patches of ground will be found near this Pokémon's nest.

Alpha Sapphire: This Pokémon exudes a weak electrical charge from all over its body that makes it take on a slight glow in darkness. Raichu plants its tail in the ground to discharge electricity.

Sun: It unleashes electric shocks that can reach 100,000 volts. When agitated, it can knock out even an Indian elephant.

Moon: It becomes aggressive when it has electricity stored up. At such times, even its Trainer has to take care to avoid being attacked.

Ultra Sun: As electricity builds up inside its body, it becomes more aggressive. One theory is that the electricity buildup is actually causing stress.

Ultra Moon: Because so many Trainers like the way Pikachu looks, you don't see this Pokémon very often.

Shield: If its electric pouches run empty, it raises its tail to gather electricity from the atmosphere.

Legends: Arceus: It can discharge bursts of electricity exceeding 100,000 volts— a single strike with that amount of power would incapacitate one of the Copperajah of my homeland.
