Battle Moveset

A Good Moveset for Dragonite would have to be this:

Attacks:

Hidden Power [Flying] / Aerial Ace
Earthquake
Dragon Dance
Thunder / Thunderbolt

Items Attached:

Leftovers OR
Lum Berry

Preferred Nature:

Adamant

Strategy Using Dragonite

Dragon-Dancer set-up. Makes for an effective sweeper when the main counters are out of the way (Bulky Waters, Zapdos and Skarmory if Thunder/bolt is absent). It gets a huge Attack stat and above average defences as well as a reasonable speed stat. It's a simple matter of timing Dragon Dances correctly and then going for a straight forward sweep. Thunder is a good option for hitting Bulky Waters switching in to counter and comes with the added bonus of a 30% chance of Paralysis (although this may not work in your favour against Milotic). Thunderbolt has 100% accuracy but sacrifices damage and has a weaker Paralysis chance, it's up to personal preference: Thunderbolt is reliable but Thunder makes a much larger impact.

EV Corner:

EVs: 252 Atk / 180 Spd / 76 SAtk
Adamant Nature (+Atk, -SAtk) / Lonely Nature (+Atk, -Def)

240 speed outruns Modest Magneton (among other things). With a positive nature boost and max Attack it packs a hard punch from the get-go which continues to improve as more Dragon Dances are added. The rest is thrown into Special Attack to get the most benefit from Thunder/bolt. EVs could be taken to boost Defences to make it take hits better, with a -SDef nature it'd be likely to get OHKOed by weaker Ice Beams however so that should be avoided. It has a fair few resistances so investment in defence may cater to your team's set-up.

Other Optional Sets

Dragonite @ Choice Band
Trait: Inner Focus
EVs: 76 HP / 252 Atk / 180 Spd
Adamant Nature (+Atk, -SAtk)
- Focus Punch
- Earthquake
- Hidden Power [Flying] / Aerial Ace
- Thunder / Thunderbolt / Hidden Power [Rock]

Choice Band set. It has a huge Attack stat to begin with and with the support of a good move pool it can be an effective CBer. Bulky waters will still cause problems so you may want to get Thunder or Thunderbolt to give them a decent hit as well as mislead them from the idea that it's a Choice Band Dragonite.

Dragonite @ Leftovers
Trait: Inner Focus
EVs: 52 HP / 64 Atk / 20 Spd / 252 SAtk / 120 SDef Quiet Nature (+SAtk, -Spd)
- Focus Punch
- Substitute
- Ice Beam
- Thunderbolt

An old standard. Dealt damage from both ends of the spectrum and dealt it well. EVs are incredibly difficult to balance for this set and you should probably focus it depending on how you want it to perform for your team. Other Optional Moves

Heal Bell, Light Screen, Thunder Wave, Flamethrower, Fire Blast, Haze, Surf, Roar, Agility. None of these are really useful on the main sets, barring possibly Thunder Wave which is universally useful. Haze and Roar present P/Hazing opportunities but Dragonite's move set and stats lend better to offence rather than utility. Heal Bell is an option that only a few Pokémon have so it's worth mentioning. It gets Agility but with Dragon Dance it doesn't really need it. Flamethrower and Fire Blast are special options. Surf is just a good move but very few situations would benefit from it's use as compared to other moves. Light Screen is an effective move but not much use on an offensive Pokémon.

Strategy Against Dragonite

It's 4x Ice weakness is it's Achilles heel. Since many Bulky Waters carry Ice Beam it fears them greatly and the likes of Suicune, Swampert and Milotic make up the bulk of it's common counters. Against the Dragon Dancer Zapdos can wall out it's two main physical attacks and deal decent damage with Thunderbolt (or HP Ice). Claydol does reasonably against it as well. Against the Bolt-Beam-Sub-Puncher Pokémon with balanced defences and no weakness to it's attacks fair best. Before it gets a Sub up Blissey, Regice and Snorlax all fair very well against it, since it's Subs are pretty weak Dragonite is usually forced to switch. Against the Choice Band set prediction is your best bet. Skarmory and Weezing are good bets for their resistance to a couple of it's attacks but having a good idea of what to expect makes all the difference.

Animé Appearences

Dragonite has had numerous Animé Appearences. It's first, it was a lost Pokémon at sea Drawn to the Lighthouse by Bill. Second, it was a messenger Pokémon in use by Mewtwo. Then it was owned by Drake and used in his Orange League Cup battle against Ash where it was beaten by Pikachu. Then it was created as in Illusion by ghosts in a forest. After that, Team Rocket dreamed that someone would trade a Dragonite for their stolen Mini-Ditto. After that, it was owned by Lance who used it to stop Team Rocket and capture the Red Gyarados. A while after that, it was guarding the Dragon Fang and got tricked by Team Rocket into thinking that Ash & Co. were trying to steal it and had to have a vicious battle against Ash's Charizard. Off in the Hoenn region a year afterwards, Lance used his Dragonite to help qwell Groudon & Kyogre and finally Professor Oak has one and tried to use it to stop the onslaught of the Mirage Pokémon Episode 13: Mystery At The Lighthouse!
