I would use dark type Pokémon my team would be zoroark,liepard,umbreon,bisharp and spiritomb

Mine wouldn't be 1 specific type but I know that psychic ice and water would be included

definitely steel. their defense is unmatched and very little is strong against them. i always have at least one steel type in my party. they have fairly high attack, one of them can take down entire parties if utilized correctly.

I would definitely have to go with Steel.  They are my favorite type of Pokemon, plus they are very tough.  Making the right team would just be really awesome and Powerful.

I would have dragon type Pokémon in my gym because they are very power Pokémon in my opinion.

Being imaginative and semi-unrealistic, I would choose two types for on gym.

I'm sorry, but my likes for Dark and Fire are too close to each other that it's literally impossible on what I like better, and makes it even harder when Houndoom is my favorite Pokémon since I first seen it.

So yea, let me bask in my glory of my Dark/Fire gym and deal with it ;-;.

Fire,electric or dragon i like these best

it would have to be electric with electivire as a partner and also having electabuzz ,luxray, and elekid,alongside ampharos and magneton

Normal slaking as my partner jiggypuff as my backup and snorlaxs for fun

catfight09 : My gym would be dragon type definatly

My gym type would be legendaries. For the first time you battle me I would use Manaphy lvl 46, Shaymin (land forme) lvl 47, Mew lvl 47, Celebi lvl 48, and Jirachi lvl 48. After beating the E4 I would use Kyurem lvl 67, Giratina lvl 67, Zekrom lvl 68, Reshiram lvl 68, Deoxys lvl 69, and Arceus lvl 70. Every time after that I would focus on each generation, and all pokemon will be lvl 75. I will use all that I can from the generation. Gen I (3 birds and mew duo). Gen II (3 dogs, tower duo, and celebi). Gen III (first time) (3 regis and latis). Gen III (second time) (weather trio, jirachi, and deoxys). Gen IV (first time) (3 lake spirits and creation trio). Gen IV (second time) (Manaphy, Phione, and the lunar duo). Gen IV (third time) (Heatran, Shaymin, Regigigas, and Arceus). Gen V (first time) (Victini and the Musketeers). Gen V (second time) (Kami trio and Genesect). Gen V (third time) (Tao trio and meloetta).

Hands down Fire Types. And I would have a Snorlax that knew Flamethrower, Fire Punch and Fire Blast. It would know more than four moves since in reality they don't have the four move restriction they have in game. 

Fire and dragon type. Because fire is my specialty and dragons don't have much weakness.

Well..Ive always loved fire types..but mine would mainly be mixed. They would all know one type of move. Like each one would know at least a fire move. Either that or tons and lengs. I always have one. Its so hard to decided which one to chose or not. XD

i would have a mixed gym with my team being dragonite, samurott, pikachu, togekiss, charizard and torterra

I will  have to say if I had a gym it be an eevee and its evolutions.

My pokemon gym would have two types water and dragon.

I would want Electric/Water/Steel My team would be Raichu,Mamoswine,Metagross,Raikou,Suicune,and Jolteon But If I have to have only 1 type it would obviously be water with Mamoswine,Suicune, Empoleon, Pachirisu, Floatzel,and Kyogre

If I were a gym leader I would have powerful dragon types like Dragonite and Rayquaza or Altaria and Charizard.
