>>33295843I'm pretty sure the original number planned for Gen I was 190, not 250+. This is also noted by the 39 Missingno variants in Gen I being their remnants. Some were introduced later in Gen II, but some surely never saw the light of day. Some were totally redone, like splitting Proto-Suicune(pic related) into its final self and Raikou. Though we don't know what Johtomon were actually planned for Gen I or planned afterwards, but I think Ho-oh is the only one confirmed.
