>mew, the ancestor of all pokemon, is psychic type instead of normal type
>lugia, the guardian of the sea, is psychic/flying instead of flying/water
>deoxys, a mutated space virus, is a boring pure psychic type instead of a cool and unique typing like psychic/poison
>as of gen 7, there are 20 (twenty) psychic type legendaries, not counting form changes (the number goes up to 29 if you do)
>plenty of legendaries will generally be psychic type for no reason whatsoever
