I am very sorry I forgot to take the screenshot before the first gym kanto (spare me)
But I can exactly tell you the changes that happened.
I promise to take the screenshot from next the next gym
Before:
Oddish = level 13 , absorb move one hits geodude but it survives due to sturdy geodude hits oddish to half hp, another absorb faints it.
Next poke onix, Oddish one hits it but survives due to sturdy. Onix hits Oddish, oddish faints.
Budew = budew comes in and defeats onix with absorb (lvl 10)
