I've always known they were easy, but never to this extent. Dunsparce's Headbutt can KO practically any foe within two hits. I managed to beat
LeafGreen with nothing but a Farfetch'd a while back, but that was actually somewhat challenging.
If anyone here has easy access to
Pokemon Red or
Blue, perhaps you could replicate a glitch I once encountered: I used my Master Ball on a wild Machoke [don't judge me; I was seven years old and that ***** was at least level 42] in Victory Road, only to discover upon reaching the Indigo Plateau Pokemon Centre that all my boxed Pokemon had become
invisible level-1 Rhydons with no attacks. The Name Rater considered them to be traded Pokemon, so he refused to let me give them distinguishable names. Needless to say, I started a new game shortly thereafter.
None of this is made up or copypasta'd. It should be noted that my mystery Pokemon were slightly different than the regular PC4SH in that their name field was completely empty, and that they didn't seem to learn any attacks naturally. I can remember teaching Surf to the ones I used in battle. So, who's up for a little glitch-investigation?
