All of it's base stats are the same, so why can the HP stat be higher?
A Pokémon's base stats will most often have the greatest influence over their specific stats at any level. Disregarding individual values, effort values, and Nature, a level 100 Pokémon's stats in Attack, Defense, Speed, Special Attack, and Special Defense will be exactly 5 more than double its base stats in each, while the HP stat will be 110 plus double the base stat (except in the case of Shedinja, whose HP is always 1).
It works differently for HP.
