Given that anything I change might have unforeseen consequences...
oh...
... well I'd probably stop myself from picking Litten as my first Alolan starter back in Pokemon Moon.
Litten and Torracat had me excited for a good looking cat starter final evo and I will never forgive Incineroar for the way it looks. Heck, I've been looking up the final stages for the starters in new Pokemon games since then because I don't want that level of disappointment again. It's still my only time ever boxing my starter in a Pokemon game on a normal playthrough.
Anyway... I doubt I'd hate it as much if I wasn't so let down by two great looking cats evolving into a wrestler wearing a cat suit, so stopping myself from picking Litten and going with one of the other starters and encountering Incineroar for the first time in a different fashion (like on the rivals team for example) is probably enough to result in me not hating it. I probably still wouldn't like it, but at least I wouldn't hate it. Oh well... at least they gave us a good looking fully evolved cat starter in gen 9.
