Any thoughts on our potential UU Pokemon Aggron? Speculation right now, Aggron is a potent force in the UU tier now thanks to Head Smash. Adamant + Polish with Life Orb is deadly as Head Smash deals a max of 77.92% on 252 / 252 Milotic. Deals a minimum of 52.23% on 252 / 252 Slowbro. It has Aqua Tail to hit Donphan who resist Head Smash - although not a wise idea to attack it when its HP is high. Whats worst is that its 180 Def can take priority from Azumarill and such.
Aggron
@ Life Orb
Adamant Nature (Atk+ / SpA-)
252 Atk / 4 Def / 252 Spe
- Rock Polish
- Head Smash
- Aqua Tail
- Earthquake / Bullet Punch
I also see simple Choice Bander being quite effective with Head Smash. Some damage calculatios by Libelldra Calculator.
Adamant Head Smash vs Max/Max Milotic
76% - 90% 15% to OHKO with SR up. Wow, this has a chance to OHKO Max/Max Milotic. Even CB Rhyperior looks sad compared to this. And with Max Speed you outspeed Max/Max Def Milotic by... 1 point ;).
Adamant Head Smash vs Standard Defensive Tangrowth
56% - 65% - Clear 2OHKO and you can easily outspeed defensive Tangrowth.
Adamant Head Smash vs Max/Max Slowbro
61% - 72% - Clear 2OHKO and Slowbro is slower then you, so... yeah ;).
Adamant Aqua Tail vs Max/Max Donphan
47% - 56% - 2OHKO with SR up and there's still a chance for 2OHKO even without SR. Like with Tangrowth, you can easily outspeed defensive Donphan.
Adamant Earthquake vs Max HP Steelix
49% - 58% - 2OHKO with SR up and still a good chance for it without SR up. Also, you're faster then Steelix ;). With Aqua Tail, you still have a really good 77% to 2OHKO Steelix with SR up.
Nidoqueen also is 2OHKOed like Steelix by both Aqua Tail and Earthquake. Also 40 speed variants are slower then Max Speed Aggron. Heck, Aggron needs only 172 Speed EVs with Adamant nature to outspeed 40 speed Relaxed Nidoqueen.
Hmmm... for me in other words if you'll get Aggron on battlefield (and with his titanic defence and really good resistances it won't be that hard) you must predict or something will die ;). I prefer to use Aggron with Head Smash as a Choice Bander then CB Rhyperior if it drops to UU.
