This is a minor one even within the context of its franchise. There are a lot bigger Pokemon butterflies that range from the series never starting up at all, never becoming ultra-popular, the seizure incident never happening, to even stuff like Pikachu remaining an obscurity rather than becoming its standard bearer.
Erika, who in the final games became a grass-type gym leader in Celadon City, was apparently originally slated to be a ghost-type leader in Lavender Town before it shook out differently.
Some of that concept still appeared in her Gen I design, even though it was being moved away from as early as Yellow (subtly changing the way her clothes were folded to remove the death implication), and every later depiction reinforced her as the grass flower lady. Now the thing is that the actual ghost specialist in Gen I , Elite Agatha, is clearly a normal person-
-and Ghost Erika just from her design is very heavily implied not to be, with her art showing her as some kind of undead. Now, weirdly enough this would increase her prominence far beyond OTL, because Lavender Town became an internet creepypasta campfire story extravaganza from the get go, and having a creepy (insert undead/possession type here) gym leader there would just pour more napalm on the fire.
