There was a disgusting lack of Hoenn Pokemon submitted so I thought I'd fix that.
Torkoal [Optimized]
Abilities: White Smoke/Drought
(Shell Armor)
Stats: 90/85/150/95/80/20 [520 BST]
Added Moves: Morning Sun, Giga Drain
Summary of Changes: +20 HP, +10 Def, SpA, and SpD. Added Morning Sun and Giga Drain.
Overview: Torkoal's biggest weakness previously was it's relatively low SpD, and lack of recovery letting it get worn down easily. With improved bulk, especially on the special side, and a great recovery move to use in the sun, Torkoal will find more opportunities to come in and set weather and Spin away hazards for teammates. It also serves as a good check to the various Fairies in the OU tier, while also threatening Corvinight with Fire STAB and Seismitoad with a Grass move of choice between Giga Drain and Solar Beam.
Mawile [Optimized]
Abilities: Intimidate/Hyper Cutter
(Huge Power)
Stats: 50/55/125/85/95/50 [460 BST]
Added Moves: Moonblast, Moonlight, Spikes
Summary of Changes: Swap Atk with SpA, +40 Def and SpD, Replace Sheer Force with Huge Power.
Overview: This stat spread is designed such that Mawile regular can recreate the intense power of its Mega form, or it can be a legit physical wall with Intimidate. Adamant Huge Power Choice Band Mawile Optimized hits an attack stat of 687, which is marginally higher than Adamant Mega-Maw's 678. On the other hand, if you go the defensive/utility rout, Mawile will be able to come in easily on most physical attackers, (that lack Defiant), and set up Spikes, while using Moonlight to heal off chip damage.
Shiftry [Optimized]
Abilities: Chlorophyll/Early Bird
(Pickpocket)
Stats: 90/100/75/110/75/80 [530 BST]
Added Moves: Flamethrower
Summary of Changes: +15 Def and SpD, +20 SpA. Gains Flamethrower so that you don't need to rely on Heat Miss.
Overview: More bulk and power to bring it closer to OU level. With its STABs + Fire move it can hit everything in OU for at least neutral damage except Hydreigon and Kammo-o, and with Chlorophyll active it outspeeds anything slower than a base speed 108+ Scarfer even with a Modest Nature.
