Mewtwo is great but I think Arcanine is a perfect mix of Cool, cute, and tough that makes pokemon as a whole an attractive series. He's a giant dog who breathes fire and you can ride him.
Damn Mewtwo is stiff competition.
Neither will survive Gengar/Snorlax though
I like both a lot tbh. In the past it would have been mewtwo for me easily. I used him to solo entire teams cause i was cheap. Now im not sure
