If it weren't for the Kalos Native crap in tournaments, I wouldn't be SRing for this guy, since I already have a 31/x/31/31/31/31 Timid one from Heartgold.
Timid Mewtwo
IVs: 31/30/28/31/23-24/31
Kinda wished that the attack and Sp. Def were switched, but it probably doesn't make a difference. Too bad that in order to do a proper Mega Mewtwo X, I have to go back two generations. This is a reset that I wasn't really eager to do but felt I had to do -___-. I'm still using my flawless Timid one in regular uber battles and situations where anything can be used.
Yeah, fuck that.
Jolly Mewtwo
IVs: 31/31/31/29/31/31
Tutors: Low Kick, Ice Punch, Zen Headbutt, Fire Punch or Drain Punch
Hasty Mewtwo
IVs: 31/31/30/31/31/31
Tutors: Low Kick, Ice Punch, Fire Punch, Zen Headbutt
Note: Rebattle Code Used for Both of Them
So in my Heartgold, I decided to get my RNG on again after a couple months, do a bunch of Mewtwos in Dusk Balls to confuse opponents, give them good move tutors, and transfer them over. Hasty can run Mega Mewtwo X or Mega Mewtwo Y. Mega Mewtwo Y has a base 150 Atk and Low Kick will destroy Ttar and 2HKO Dialga. All I need now is to do a Naive one and that will complete my collection. Doing Mewtwo in X and Y for me is extremely pointless. #FuckKalosNativeRules
