Your least used type.

[giradialkia]

I generally don't use Bug types too often at all. The same can be said for Dark types, too- and Rock types. For all their defensive hype, they generally haven't done too well for me.

Otherwise I tend to use a wide enough variety of types across the games I own, though I'll almost always use a Fire type of some kind.

 

[ISA56 2.0]

I seldom use Bug, Grass, or Poison type Pokémon because I find their overall designs goofy and their overall type coverage rather lacking.

 

[CliCliW]

I tend to not use Bug types (although I always want to train one up to keep for the rest of the game like Dustox or something, and I used Galvantula in my White playthrough)
Steel types I didn't use for a long time until I discovered Excadrill
Dark types always seem useless to me, usually I just have a pokemon on my team that knows Bite or Crunch or some other Dark Type attack.
And last but not least - Poison. Is there a more useless type?

Bug/Steel/Ground/Rock

Although in B2 it's Flying.

 

[Sheep]

Hm.. poison, bug, steel, I guess. I'm just not a fan of those first two types much and there aren't many steel types that are available early enough. :(

 

[tnfsf11]

Normal, and Flying ofc, since nearly every Flying type poke is semi Normal, except legendaries maybe.
The ONLY 2 Normal pokes I used were Rattata, which wasn't optional because I was nuzlocking, and Clefairy, because back when I was a noob I used to save state all the time while playing Pokemon to get a good move outta Metronome xD

Good question. I think mine would be Rock/Ground, I rarely use those types in comparison to others.

 

[T!M]

I use Bugs, Ghosts and Normals less than anything else, if at all. The obvious exceptions are my current and previous teams. As I used Joltik and I'm currently using Leavanny.

 

[Bounsweet]

Rock-types for me, not a lot of them really appeal to me and I find that Ground-types can do the same as them, but better, honestly.​

 

[BrandoSheriff]

For me, it'd have to be bug type. I honestly haven't used a bug type Pokemon since Butterfree in R/B/Y.

 

[Grif of Hearts]

There seem to be a few I tend to skip over, or only use because it's a secondary type. I have nothing against them, but they just seem to be less important than others.

Steel.
Dark.
Bug.
Ghost.
Rock.

Ironically, my current Black 2 team consists of Escavalier, Graveler and Litwick. I've been trying to use Pokémon I never had the chance to the first time around, which explains the current team being made up of abnormalities.

You'll very rarely see me using:

- Normal-types, as they're mostly useless for an actual fight. They're the so-called jack of all trades, master of none. I prefer going through battles with a surgical approach, not a brute force approach.

- Poison-types, as they're only most effective against grass-types, which are already weak against a lot of other types. Also, the only poison-type move that really matters, which would be Toxic, can be learned by a lot of other Pokémon, not just those Poison-types.

 

[Brendino]

The two that I use the least would have to be Electric and Rock types.

I never really use any Electric Pokemon since none of them appeal to me- I'll generally give any Electric type moves to non-Electric Pokemon. As for Rock, they seem to have way too many weaknesses, so I usually just stay away from them.

 

[Creame]

I rarely use Poison-type Pokémon, why use a type which is only super effective on Grass-type Pokémons..
And besides, there's no Poison-type Pokémon I really like by its looks..

 

[Palkia]

Easily Ghost types. I always find them when my team is full and I don't really care for the type too much.

I also don't use Bug and Ice types very much.

 

[Satoshi Ookami]

Grass types. I always avoid using them.

 

[T!M]

A couple of members have reminded me of types I don't use either.

Along with Normal, Ghosts and Bug. I also rarely use Poison and Ice.

Lol. Thanks guys.

 

[kosuke]

My least used type would be Ghost. Most of their designs are not that good, and their moves can't hit normal types.

 

[alisaie]

I'm fairly certain that it is either Steel, Fighting, Poison, or Rock but I can't be sure. I have used at least one Pokemon from each type but definitely not as often as the other types. It's not that I don't like the types it is just that I tend to consider other Pokemon with other types before these.

 

[Dangelitus]

The type i least use is poison, and the second grass, in the case of the posion, because except for the sludge bomb they don't have many good attacks; in the case of the grass i guess its because they have important weaknesses (fly, ice, fire) and in general they are slow (i now there are some type grass fast, but not many)
