Latios Latios has been a great Pokemon ever since it's creation in Generation 3. Latios was first allowed in OU in Generation 5 and that is where it remains as of today. With the introduction of X/Y Latios gained a new toy in the form of Defog, which allows it to function as a Hazard Remover. Latios has good base stats across the board with 130 Special Attack, 110 Speed and usable Defenses and a great ability in Levitate. Gen 6 wasn't only kind to Latios though as Draco Meteor was nerfed, Fairies were introduced, and new checks and counters to Latios have been introduced such as Bisharp and Aegislash. Life Orb Latios (M) @ Life Orb Trait: Levitate EVs: 4 HP / 252 SAtk / 252 Spd Timid Nature (+Spd, -Atk) - Draco Meteor - Psyshock - Surf / Hidden Power [Fire] / Thunderbolt / Roost - Defog / Roost Life Orb amplifies Latios' amazing Special Attack to cause obscene damage while still being able to alternate between moves. Draco Meteor hits anything that doesn't resist it or have very high Special Defense really hard. Psyshock stops Blissey and Chansey from walling Latios along with hitting Fighting and Poison types such as Conkeldurr and Mega Venusaur which would cause problems. The next moveslot is between Surf, Hidden Power [Fire], Thunderbolt, and Roost. Surf hits Tyranitar, Excadrill, and Heatran for solid damage. Hidden Power [Fire] will defeat Ferrothorn and Scizor, but forces you to use 30 Speed IVs, making you not tie with +Speed Base 110's. Defog is a great move that removes hazards on both sides of the field which can be an important thing for certain teams. Roost is great for healing, but Defog and Coverage moves are both quite tempting. Choice Latios (M) @ Choice Scarf / Choice Specs Trait: Levitate EVs: 4 HP / 252 SAtk / 252 Spd Timid Nature (+Spd, -Atk) - Draco Meteor - Psyshock - Surf / Hidden Power [Fire] - Trick / Defog Latios has great Special Attack and Speed, but they can be augmented further by Choice Specs or Choice Scarf. With a Choice Scarf, Latios' Speed reaches an astounding 525, outspeeding anything except more obscure Scarfers such as Scarf Greninja. Choice Specs allows Latios to hit with ridiculous power. A Draco Meteor from Choice Specs Latios will OHKO Rotom-W that aren't fully invested in Special Defense. Draco Meteor is a necessary move to have on Latios because of the sheer power that it has, not much can safely switch in on it. Psyshock can defeat Blissey and Chansey along with other threats that it hits super-effectively. Surf can do decent damage to Heatran and Tyranitar as they switch in, but most of the time it isn't enough. Hidden Power [Fire] deals with Genesect, Scizor, and Ferrothorn which are common counters to Latios otherwise. Trick can cripple an opposing Pokemon, especially more stallish Pokemon such as Ferrothorn and Chansey. Defog removes hazards, but can give the opponent a free turn to act as you are forced to switch which may be dangerous. Other Options Shadow Ball can be used on a Choice Specs Latios to hit Aegislash switch-ins hard. Roost can be used on the third slot of the Life Orb set, but Latias plays the bulky Defogger role better generally. Dragon Pulse can be used on Choice Latios, but the coverage moves and the support move are of importance. An Offensive Calm Mind set is usable, but Latias can fill the role better, and neither can pull the set off as well as they used to could. Expert Belt is usable on the Life Orb set, but the constant power is generally preferred. Reflect, Light Screen, and Tailwind are moves that Latios can viably use to support its teammates, but these sets are outclassed by other Pokemon. Dragon Dance bolsters Latios' speed to outspeed, or at least tie with the entire scarfed metagame Checks and Counters Tyranitar can take anything from Latios except for two Earthquakes and trap it with Pursuit. Heatran has an easy time taking Latios' attacks, except for an Earthquake, and can Toxic Stall or 2HKO Latios with Flash Cannon. Aegislash takes anything except for a rare Shadow Ball from Choice Specs Latios. Ferrothorn can take any attack from Latios, but is crippled by Trick. Bulky Fairies such as Clefable and Sylveon are somewhat reliable ways to defeat Latios. Bisharp gets its Attack boosted by two stages by Defog and can OHKO Latios with Sucker Punch or Knock Off and can even Pursuit trap it, but Earthquake and Surf wear it down fast so it has to be played well. Mega Scizor can tank most of Latios' attacks and fire back with a super-effective U-Turn!
