It lists all of the dark Pokemon from all of the games.
Weavile
Tyranitar
Darkrai (Darkrai is an uber not allowed in competitions so to replace it id say Umbreon)
Houndoom
Drapion
Spiritomb
Hope this helps I train Dark type Pokemon myself.

Darkrai is the best dark Pokemon in my opinion, the Pokemon is very fast and if you teach it dark void the become becomes pretty much unstopable.
The Dark type in Pokemon has many competitive Pokemon of pure or dual type. Common favorites include Absol, Tyranitar, Zoroark, and Hydreigon.
Succceffuly compleeet.... game. and you can find in near the forest
Hydreigon is probably the best, since its stats are very good all round, but it depends on EV and IV training.
I found umbreon good, by i think there are others
Look on supercheats pokedex and look up dark pokemon, and compare the stats and moves
poocheyena is 1
darkria
=====================DARKRAI===========
Darkrai learns the move Dark Void at lvl 66. Dark Void puts Pokemon to sleep. It's a very powerful move!! Gotta Catch em' ALL!!
Dark type have weakneses to: Fighting Bug You may also need to find out whether the dark type Pokemon has a dual type for example: Spiritomb is also ghost meaning it has no weaknesses Murkrow or Honchkrow are part flying as well meaning an electric or rock movde can take it out
Pokemon 222 on Pokemon diamond is (CORSOLA) there is Pokemon 222 and you have to gts trade or link trade it to get
ADAE-636791C0 is the AR ID for Pokemon Diamond
You can not get dark Pokemon on Pokemon diamond and pearl
NO!NO!NO!NO!NO!NO!NO!NO!NO!
You can't. There is no such thing in any legit version of Diamond or Pearl.
In Pokemon Diamond, I would say it is easy to find a Noctowl or Hoothoot after it becomes dark.
Firstly its Darkry not dark cry and secondly its a Pokemon obtained by hacking pearl or diamond.
i would have to say Dark Rai
