>>42357449pikachi and eevee have similar base stat totals, which means that the values of all of their base stats, attack, defence, etc, when totaled up are similar to each other's. Pichu and marill have a much larger disparity, at a 40 point difference, but togepi, when replacing pichu, would make the totals much closer, and comparable to the difference between pikachu and eevee
