All you need is a Ditto and you'll be able to get other natures by breeding. Anyway, here's something for Dragonite:
Dragonite @ Salac Berry/Persim Berry
- Dragon Claw/Outrage
- Earthquake/Stone Edge
- ThunderPunch/Fire Punch
- Dragon Dance
Naughty Nature boosts your Attack stat, so a Physical sweeping set is best. Dragon Dance to boost Attack and Speed, Dragon Claw/Outrage for STAB, Earthquake or Stone Edge for extra type coverage. Choose ThunderPunch if you pick Earthquake, and Fire Punch if you choose Stone Edge to get the best type coverage. For the hold item, choose Salac Berry if you want Dragon Claw as your STAB move, and Persim Berry if you choose Outrage.
