Metagross, The Iron Leg Pokémon. Metang combined to form it. With four brains, it has the intelligence of a supercomputer. It folds its four legs when flying. Its four brains are said to be superior to a supercomputer. When hunting, this POKéMON pins the prey to the ground under its massive body. It then eats the helpless victim using the large mouth on its stomach. This Pokémon can float in the air by tucking in its four legs. With four linked brains, it's more intelligent than a supercomputer, and it uses calculations to analyze foes.

Overview

When released in 3rd Generation, Metagross was a monster. When 4th Gen came around, Metagross was still just as good, and this hulking chunk of metal worked well either using lead sets or just destroying the leftovers of teams late game. However, in 5th generation, Metagross' flaws have become ever more apparent. With the nerfing of Explosion's power, more Pokemon resistant to his two STABs, low speed, and weaknesses to Fire and Ground are all hurting Metagross more this generation than any other. But despite this, Metagross is still one of the more used Pokemon thanks to its enormous Attack and Defense stats, and its respectable Special stats and HP. It also has a decent movepool to either work as a supporting lead, or as a boosting sweeper.

Abilities

Clear Body: Metagross' stats cannot be lowered by an opponent, a useful ability as it prevents Intimidate attack drops, which otherwise could hinder Metagross (though protection from every other stat drop is pretty useful too).
Light Metal: Halves Metagross' weight, basically useless especially in comparison to Clear Body, as damage from Low Kick isn't going to be overly devastating (besides the fact it isn't used much).

Movesets

This Meta is Gross

-Stealth Rock
-Meteor Mash
-Hammer Arm / Earthquake
-Pursuit
Item Attached: Leftovers
Ability: Clear Body
EVs and Nature:
EVs: 252 HP / 96 Atk / 160 SDef
Adamant Nature (+Atk, -SAtk)

Metagross has so much it can do, and this is just its standard lead set. Stealth Rock is the main point of this set, providing your team with a useful entry hazard. Metoer Mash is powerful STAB and may even give Metagross a +1 boost to its attack. Earthquake is for hitting Pokemon like Jirachi and Tentacruel which would otherwise wall Metagross, while Hammer Arm can be used for powerful hits on regular steel types and decent damage on Rotom-W and Skarmory. Pursuit takes out Psychics and Ghosts on the switch out, generally Latios stuck with a resisted move due to a choice item. The EVs provide Metagross with decent bulk, allowing it to tank moves from both physical and special attackers while still being able to do decent damage in return (which the Adamant nature helps with). Leftovers is for some annoying survivability, making it so that Metagross will not go down easily and stay around much longer than your opponent would otherwise want.

250 Gigabytes of RAM

-Agility
-Zen Headbutt
-Earthquake
-Meteor Mash / Ice Punch
Item Attached: Life Orb
Ability: Clear Body
EVs and Nature:
EVs: 4 HP / 252 Atk / 252 Spe
Jolly Nature (+Spe, -SAtk)

Agiligross has been around since his arrival to Pokemon, albeit with a few changes. This is the best out of Metagross' boosting sets, as Agility boosts its poor speed to ridiculous heights. Zen Headbutt if for STAB (and that 20% flinch rate will have fun with your opponents), while Earthquake is used for coverage. Meteor Mash is recommended over Ice Punch, thanks to its STAB and chance for a +1 attack boost, but Ice Punch is for more solid hits on certain Pokemon (Dragonite, Skarmory, etc) if your team needs them. Life Orb is for more power, but thanks to the recoil you'll need to do your sweeping relatively quickly, and the EVs and Nature are for high speed and attack.

"I'm Sorry Dave, But I'm Afraid I will Do That"

-Meteor Mash
-Hammer Arm
-Bullet Punch
-Zen Headbutt / Thunderpunch / Pursuit
Item Attached: Choice Band
Ability: Clear Body
EVs and Nature:
EVs: 4 HP / 252 Atk / 252 Spe
Adamant Nature (+Atk, -SAtk) or Jolly Nature (+Spe, -SAtk)

Metagross with Choice Band attached hits with the power of a nuclear warhead. Meteor Mash is Metagross' primary STAB move, while still giving the possibility of a +1 attack boost. Hammer Arm is used for coverage on other Steel types, and the speed drop isn't really a problem (even lets you hit a Roosting Skarmory for more damage once you're slower). Bullet Punch is additional STAB, and useful priority for revenge kills. What you choose for the last slot depends on what you need. Zen Headbutt is a strong STAB move that hits Pokemon like Tentacruel and Amoonguss for significant damage, while Thunderpunch can hit some Water types harder (Gyarados for example). Pursuit is an option if you want to trap Psychics or Ghosts, or just get a revenge kill on a switching out Pokemon (though more HP EVs are advisable with Pursuit in case they do stay in). The nature choice is based upon whether or not you want more power or more speed.

DragonBall Z Fusion Dance Anyone?

-Meteor Mash
-Zen Headbutt / Earthquake
-Grass Knot
-Hidden Power Fire
Item Attached: Life Orb
Ability: Clear Body
EVs and Nature:
EVs: 252 Atk / 252 SAtk / 4 Spe
Naughty Nature (+Atk, -SDef) or Naive Nature (+Spe, -SDef)

This is an unusual set that utilizes Metagross' decent Special Attack stat. Meteor Mash, STAB, attack boost, etc. etc. I think you know by now. Zen Headbutt hits things weak to it hard, and is good neutral coverage on Rotom-W, while Earthquake hits specially defensive Steels or anything named Heatran. Grass Knot is used for bulky Water types and Hippowdons. HP Fire hits physically defensive Steels such as Skarmory and Ferrothorn. Life Orb is used for a boost in power, while the nature choice is dependent on whether you want Metagross to hit harder or to have a chance of outrunning some Pokemon.

Other Options

Explosion, Gravity, Ice Punch, Iron Head, Magnet Rise, Rock Slide, Trick
Explosion can be used on most likely the Choice Band set just to completely obliterate something just before Metagross goes down.
Gravity is useful against Pokemon like Rotom-W and Skarmory as it allows for Metagross to hit them with Earthquake, the only problem is you'd have to sacrifice some coverage for it.
Ice Punch can be used to hit Gliscor and Dragonite hard, as Roost Gliscor is a pretty good counter to Metagross.
Iron Head can be used as alternative STAB over Meteor Mash if you don't like the 85% accuracy, but comes at the cost of a lot of power.
Magnet Rise sounds good in theory as it eliminates one of Metagross' weaknesses, but doesn't last long and requires a loss of coverage to provide for it.
Rock Slide can be used for coverage on Flying types, but generally isn't worth it.
Trick can be used on the Choice Band set, or on an Iron Ball set or whatnot to work towards crippling your opponent.

Double & Triple Battle Options

Metagross works best in this environment as either a full out attacker, or as a Choice Scarf Pokemon, generally being geared towards resisting moves like Rock Slide and just attempting to damage the opponent as much as possible.

Partners

Anything that resists Ground (Flying types, Levitate Pokemon, etc.) are good partners for Metagross as they help to avoid one of its major weaknesses. Ninjask / Gorebyss also make good partners as they can pass additional Speed to Metagross, which it can use.

Countering Metagross

The number one counter to Metagross is Slowbro, as it resists everything Metagross uses, excluding Thunderpunch, which even the Choice Band set only can get a 2HKO with, which can be avoided through Regenerator and Slack Off. Slowbro can also cripple Metagross with different statuses, or just spam Scald and hope for a burn. Skarmory makes a good check to most of the sets as it can tank anything Metagross hits it with and Whirlwind it out. Most physically defensive Steels can handle any set other than the mixed. Rotom-W does well as Metagross has nothing that gets used much that hits it super effectively and it can take advantage of its lower Special Defense. Bulky Water types also fare well against Metagross, and can either burn it or stall it out in return.
