Yeah, Toxic + Leech Seed combo FTW!
It was a lot easier once they added Egg Moves and breeding though. Getting OP Toxic on things was difficult in Gen 1 without multiple copies of the game and more than one Game Boy (or Pokémon Stadium).
@Headpopper : Yeah, I'd actually forgotten about Kabuto. I always chose my favourite Cthulhu-faced Nautilus, Omastar, instead.
@VaultDweller95 : Gecko-backed Reinforced Leather Armour was my primary Armour of choice in New Vegas. I switched to the Reinforced Metal variant on latter playthroughs though. Geckos were just adorable. I'd totally make friends with them and the Yao Guai.
Which brings me back to my Battle Bear mount. Seriously, a ridable, armoured Yao Guai mount with mounted Miniguns would just be awesome.
