>>523411971: Zero editing to unown versions:
Make a neutral "universal" form.
Make that the only catchable one.
Talk to some ancient fuck in a shed somewhere to get the book of the unnown.
Go around touching stone carvings in ruins around the map to register unown forms to the book.
Use the book like a rotom catalog to change the unown forms.
2: Minor editing to unown versions.
Everything in 1 + you could give them a special move called letter power that was basically a beam type move that shoots out letters matching the unown and some retarded pointless gimmick like if the letter matches the first letter of the opposing pokemon's name, the move will go first, or have higher accuracy or some shit.
3: A lot of editing to the unown versions.
Everything in 1 and 2 + each form has a different double typing.
