1) It isn't guaranteed anythingMETAGROSS
Moveset Name: METAGROSS MIXED TANK
Move 1: Meteor Mash
Move 2: Earthquake
Move 3: Ice Punch
Move 4: Explosion
Item:Leftovers
Ability:Clear Body
Nature(s): Adamant/Careful (I prefer Adamant for the extra power, but that's mostly because the metagross i bred only has 4 attack IVS lol----at least it has flawless in HP Defense and SPDef)
EVs: Ordered HP252/Atk4/SpD252
Although this set is surprising to see, it is no joke. This Metagross is almost GUARANTEED to take out at least two pokes on the other team. With this specially defensive EV spread combined with Metagross's naturally stellar Defense stat and HUGE Attack stat, Metagross can take out many threats including the almighty Latias with Ice Punch after taking only 1/3 damage from a +2 surf. Meteor Mash was chosen not only for being a 150 base power move with stab, but it was also chosen for its chance to raise Metagross's Attack up one stage for a chance to make its explosive finish much more devastating. Earthquake is used to take out Fire types. Infact, this Metagross at full HP is actually able to take Non speced Heatran's fire blast and survive and OHKO it with earthquake. Also, this metagross takes ABSOLUTELY NOTHING FROM RESISTED SPECIAL ATTACKS. Infact Metagross actually gains HP when it is hit by Starmie's unboosted ice beam. This Metagross is also not close to being 2 hit KOD by bulky Zapdos's Heat Wave and can immediately threaten it with ice punch and earthquake on the Roost. If someone sees any flaws with this set, don't be afraid to correct them in a reply. This Metagross can not only take special resisted hits, but it can also take physically resisted hits well also. You wont be disappointed when a Salamence uses Fire Blast on this Metagross after it realizes dragon claw does nothing only to see that Metagross survives and immediately decimates it with Ice Punch.
2) It takes 50% from a +2 Surf
3) Meteor Mash is base 100
4) Fire blast from LO Heatran easily OHKO's
5) Actually, it does take damage from resisted special attacks.
6) It is easily 2HKO'd by Zapdos using Heat Wave
