How the Gen 1 Pokemon Fusion Generator Works

The Gen 1 Pokemon Fusion Generator runs 4 fusion steps on Kanto Pokémon, using current base stats and types; Clefairy, for example, is Fairy type, as in games since Pokémon X and Y.

Fusion stats formula

The 6 base stats of a fusion take two thirds (67%) from the leading parent and one third (33%) from the other parent. Hit Points (HP), Special Attack (Sp. Atk) and Special Defense (Sp. Def) lean toward the Head. Attack, Defense and Speed lean toward the Body.
