I get such strong affections for my Pokémon because of my routine uses of them, and I have to tend to them with potions and stuff. They're like my electronic, cock-fighting pets. Even in my non-Nuzlocke runs (all of my runs), I'm always very cautious in trying to keep them from fainting. When they do faint, shit gets real and I intend to avenge them. In my last playthrough of LeafGreen, I never had a single Pokémon faint up to the first battle with Giovanni. Up to that point, I was considering it be a Nuzlocke run with choice. But as my Pidgeotto fainted, I thought "No... I can't abandon you, you're too valuable already. We put out so much effort together. Let's go on".
