Dragon Pokemon

kingdra -its a good choice, but you need to trade a seadra holding a dragon scale to get it

Raquaza - if you havent caught it, its in sky pilar and save when you get up to the top. but if youve defeated it, then there's no hope for you :S

Dragonite - but thats not in emerald

Milotic

... i dunno. You know how those dragon tamers can teach dragon type moves to pokemon that LOOK like dragons? Maybe you should do that for some of yours. like, Aggron can be a pretty believable dragon.

Salamence, Gyrados, Rayquaza, Latias, Latios, and Kingdra. Though, that's only my personal opinion if dragon types were needed.

I don't recommend using all dragons in your team-if you come up against an Ice type, you will have no chance.

These are 2 pokemon that I recommend:

Kingdra lv 100. Nature: Modest. Trait: Swift Swim.
Moves: Dragonbreath, Agility, Surf, Rain Dance.

Gyarados lv 100. Nature: Adamant. Trait: Intimidate.
Moves: Thunderwave, Earthquake, Body Slam/Hyper Beam, Dragon Dance.

Alteria is a somewhat good flying dragon type, with certain good moves like dragonbreathe and dragon dance, (I don't really know much of its moves)

Salamence is a very good pokemon maybe lv it to 80 and no problem with the first 2 elites, Alteria is a good pokemon, try that one, and milotic is NOT a dragon pokemon, he's a water type, Aggron is not a dragon type but very powerful against the elites. lv yourFlygon up and if he knows earthquake, u got no problem with ground type our water types.

Okay guys iv raised my dragon parties but you want to throw in giffrent types personaly I like steel types so I use aggron and metagross salamance altaria and my favorite flygon but a good mix to put in is fire type moves and rock moves or if you use pokemon like fighting types brickbreak is a reliabel move against ice types

So far I have RayQuaza,Latias,Salamence,Gyrados and Flygon,I don't know what I should choose for the last slot

Well my team consists of dragonite, milotic, tyranitar (not a dragon but looks like one and still a decent Pokemon), salamance, flygon, and latios, but I substatute him with rayquaza

My team will be Latios,Salamence,Flygon,Altaria,Raquayza, and ...Gyrados

What about huntail? That's a good Pokemon who pretty much is a dragon

My team are latios latias rayquaza Tyranitar salamence and..........dragonite
