i think kenshi and ashrah because im not good with them and im good with scorpion but i cant beat him

with kenshi is too easy
just keep doing the tele flury and if the mofo gets close do the triangle triangle square square combo while in tai chi...

Well Ive not finished it with everyone yet but most of them. But generally Ive found the Dragon quite easy to beat, if u use the Kamidogu that is.
Everyone has at least 2 or 3 style branching combos, and generally they do a decent amount of damage. I just learn them on the build up to the Dragon King, then dtart by using the combo on him that changes from style one to two, then a combo in style two, then the combo moving from style 2 into weapon style, then a combo, then switch back to style 1 and do the same. Maybe mix up a few of the combos.
Its never taken me more than 3 attempts to beat the Dragon King, but ive not done hardest difficulty yet.
I found it easiest with Jade, Shujinko, Ashrah and Tanya and hardest probably with Dairou, Hotaru (cause I enver use him so am crap with him) and also with Noob-Smoke.

I have difficulties with character that does not have long combos, such as Hotaru, Kira, Mileena, Havik and Tanya.

I had some problems to beat him with Sub-Zero

Sindel is the easiest. In either her first or second style, keep doing the four punch combo, even when he blocks. The hardest that I beat it with is Noob-Smoke. The hardest that I gave up on is Shujinko.

So far Ive had so much trouble with beating the game with Havik and Scorpion (Im wondering too). Shujinko and Ashrah were easy for me though (I was just a cheap little bastard with Ashrah, used the FF O/B move)

i believe shujinko is the easiest by far... if you use kamidogus properlly you can defeat him so easy, his combos are so long and damaging

So far Ashrah.
She has very slow recov time unless you use the f,f,o/B move. Her combos aren't strong enough.

yeah and for whatever reason, after a kamidogu Shujinko bicycle kick does like 30% damage

Given that projectile attacks are known to be totally ineffective vs. the Dragon King, I have to nominate Scorpion as my choice. That bloody spear of mine just get stuck on his armor for a second before he brushes it off Funny how people said Ashrah was hard to use, since I actually had a decent time attacking in close range with her with her flurry of punches.

Noob Smoke, since they both have combos that are so small that they barely do any damage to the DK

Noob-Smoke and Havic were the hardest for me. The easiest way to beat the Dragon King is to use three kamidogu each round and do the characters longest style branch combo.

The damage dealt to Dk increases with the number of hits you deal. Kamidogous also result in DK takin more damage. The hardest character IMO has to be mileena. short combos with no damge. She has speed, but speed is useless against dk.
The easiest to beat dk with has to be baraka. or lk, or raiden.

the hardest character to beat DK with for me is most likely just one character. and that is ashrah. I aint bad with her its just that she is my worst character. i am not bad nor good with her just in the middle i can just do fair combos. But if i am scorpion oh man he goes down like a puppet with its strings cut. All you have to do is go the komidogu and do his triangle, triangle, L1, square, square, x, x, L1. so yea bye

Mine is probably Hotaru.

I can beat the Dk EASILY with Mileena cuz im good with her and shes easy to use, but I have problems with Rayden and darrius

Hotaru.
I really just hate Hotaru.

Kira ...
