>>25107766>>25107795>>25107845I brought up the japanese name because the name shadow tag is unclear about what actually happens with the ability.
With Mean Look they use their scary eyes to prevent enemies from retreating. Shadow Tag has nothing to do eyes. Cleary it has to do with with making the enemy step on a shadow.
Shadow Tag used to be the signature move of Wobbuffet. Wobbuffet can't even learn mean look.
As I said before, It makes no sense to incorporate into a design an eye from a move animation that's not even related to it's special ability, it just so happens that the two have the same in-game effect.
I bet that they gave him a golden third eye because they were planning to make it Ghost/Psychic.
