Here's 3 Dragonites for you:
Physical Sweeper
Dragonite @ Salac Berry/Persim Berry
- Dragon Claw/Outrage
- ThunderPunch
- Earthquake
- Dragon Dance
Dragon Dance to boost Draggy's awesome Attack and more importantly, his somewhat lacking Speed. Dragon Claw/Outrage for STAB, Earthquake and ThunderPunch provide very good type coverage. Salac Berry is your item if you choose Dragon Claw as your STAB attack, and Persim Berry for Outrage to avoid the confuse effect.
Special Sweeper
Dragonite @ Choice Specs
- Draco Meteor
- Flamethrower
- Surf
- Dragon Pulse
Essentially a complete rip-off of the Salamence moveset. One Draco Meteor will do HUGE damage, and two will pretty much gurantee an KO even after the Sp.Atk drop from the first one. Flamethrower is to take out Steel-types, the only type to resist Dragon-type moves, and Surf is for Heatran, the only Pokemon who resists both Fire and Dragon-type moves. Dragon Pulse to mop up any already damaged Pokemon after Draco Meteor has run out of PP.
Or, there's this:
Dragonite @ Wise Glasses/Life Orb
- Dragon Pulse/Draco Meteor
- Ice Beam
- Thunderbolt
- Flamethrower/Surf
Simple really - Dragon Pulse/Draco Meteor for STAB, Ice Beam and Thunderbolt for coverage, and Flamethrower/Surf for a filler move. May be preferable to the previous Choice Specs moveset which sacrifices extra coverage for pure power. Your choice which one you go for.
