Evolution

Pichu #172 - It is not yet skilled at storing electricity. It may send out a jolt if amused or startled.

Pikachu #025 - It lives in forests with others. It stores electricity in the pouches on its cheeks.

Raichu #026 - Its tail discharges electricity into the ground, protecting it from getting shocked.

The whole evolutionary chain just for fun.
