You mean "couldn't care less".
And Nintega is NOT nice. He's a person that is litterally insane, an actual crazy person, who has stalked members of this form (and others) for years. Without typing out a book load of shit I can't explain it, but make no mistake. He isn't nice, harmless, or tolerable. He's f*cking horrible. He should be in jail.
MH/Professor is basically the Batman to Nintega's Joker, and that's putting it in as positive of a light as I can. It's a symbiotic relationship for sure, both in a race to out-crazy/stalk the other. From my experience though when MH is on a witch hunt, there is an actual witch.
