>>58228857Something interesting about Shedinja how it has two gameplay exceptions. First being that that it only has 1HP, not just a Base HP of 1, but always has a max HP of 1, an outright exception from the usual Stat formula. Then second, its role in its own evo line is uniquely strange compared to other Pokémon, with Nincada Evolving to Ninjask but then Shedinja just also kind appearing in the Party if possible when that happens.
There's really not too many gameplay exceptions in the series, so those few rare cases like Shedinja are interesting.
