Overpowered Pokemon

For Vulpix and Ninetales? Oof honestly that's a tough one. For the species as a whole, id probably advocate for a base stat bump to bring it back to where it was in Generation 1: +15 to Special Attack for Vulpix, +19 to Special Attack for Ninetales. This would take it from 505 Base Stat to 524, giving it 100 Special on both like it enjoyed in Generation 1 and why it was superior to Charizard from a Fire type perspective. Char may have had a better movepool(especially in Yellow compared to Red/Blue with Fly) but my Fox has similar Speed and 15 points on Special(Char's advantage was slightly better HP, Attack and Defense with Flying typing to avoid Ground. Little did that do for Ice(x2 because Gen 1 Fire doesn't resist), Electric(x2) and Rock(x4 although Rock Slide was rare).

When Gen 2 dropped, Char got a 24 point boost to Special Attack(taking it from 510 to 534 where it is now and Mega adds another 100 BST along with Type/ability changes) while Ninetales got nerfed from 524 to 505(guess they couldn't have a starter be weaker). Yet if they're going to use that argument, then why did they buff Arcanine? Arcanine was at 535 in Gen 1(so higher than Charizard and Ninetales) and goes to 555(again higher than Charizard) by adding 20 to Special Attack(and has a broken Intimidate ability to boot). Arcanine and Ninetales are tied to the hip because they're version exclusives in Red/Blue and Fire Red/Leaf Green so I'm like.. the bleep man, why the middle finger to my Fox?

Next change is to give my Foxes a 2nd Ability. To me Ninetales is generally a Drought setter but when she isn't, Flash Fire has a niche use and really isn't viable save in Doubles with Friendly Fire or a luck swap into a Fire attack. So for a new ability I'd make it take Normal moves and turn it into Ghost damage. So Tera Blast would basically be like having a Ghost Tera without having to do it. For Alolan Ninetales, shed get Refrigerate or the Normal to Ice equivalent.

Finally I'd add Fairy to Kanto Ninetales. It warrants a 2nd Typing and should mirror its Ice counterpart.

All of these changes wouldn't make my Fox OP but she'd be way stronger than she is now.

I request that they bring Earthquake back to Charizard's move pool (I'm pretty sure it used to be there) but I also want it to get Close Combat

Hmm...

It doesn't have it

I think it once did

But not anymore

And because Focus Blast doesn't have good enough accuracy and Focus Punch would require no hit and Brick Break isn't that strong

Oh LET'S GO I'VE BEEN WANTING EARTHQUAKE!!!

And I stand by Close Combat
