Another outlier is Super Smash Bros. Ultimate where the popularity of the game has caused the introduction of a second fighters pass, but the new fighters still have to be purchased as a package as individual purchases are not possible.
You can buy each of the five "challenger packs" included in the first fighters pass seperately. I imagine the second fighters pass will also offer it's six pieces of content as individual purchases too.
