>>36544314Every bug except like Pinsir and Scyther were multityped
If you read into the dev history for Gen 1, at different stages of development they had 'elements' and 'types'
This is why there's shit like Bird type which was distinct from but later rolled into Wind type to become Flying, Normal type was probably just Monster type at some point, Bugs were just either Grass or Poison and Dragons were probably just Fire types.
That accounts for a lot of the messy typing in Gen 1 and on.
