- Whitney in SS. Curse you, Attract!
- Recently, so far*, Misty in LG. I had to reset three times until I finally beat her Starmie. Curse you, Water Pulse! How dare they not make water NVE (Not Very Effective) to electric!
I still haven't had the chance to challenge Red in SS yet. So I can't say if he's extremely hard or not
*I say that because I still recently started LG, so I currently only have 4 badges.
