No doubt in my mind it's CYRAX, I guess it depends on the individual.

The last mission in konquest mode, i had to fight reptile with reptile... MY GOD!!!
I never thought i would make it!!!

But after a while or ten, the human brain beats the machine!

Without a doubt, Movado!
3 challenges, and one being sonya absolutely kicking my arse for ages!

And then Kung Lao was also pretty hard

But everyone else was quite easy

Hardlights for me:

*Sonya's mirror match
*Frost's combos, esp. style branchers
*Rayden's Style branchers!
*Shang Tsung and Cyrax had moves in combos that wouldn't connect unless you were attacking from a certain angle, so that was a bit of a pain.

Oh man, don't get me started on Raiden's style branches. I had 216 of 218 missions done and I was stuck on Mission 9 for Raiden. For a while there, I thought I would NEVER get Raiden's style branches done. They are killers on the Gamecube controller. Were for me anyway.

Raiden's style branches are hard on the Gamecube contrller! It took awhile to pull off sparky but that was because I was pressing the wrong buttons at the end without realising!

Otherwise, the Konquests were easy part from Frost's, Reptiles and Cyrax's!

For me it's Raiden's last mission, Mavado's, where he has to beat Sonya and Cyrax' where are those combos with moves with three directional buttons following.

i also found mavados quite hard, but i found drahmins final battle a bitch! and the fact that in my opinion he sux didnt help either...

I would most definitely say that Mavado.... I had a lil trouble with Jax too...but Mavado for me

Well for me it was nitara because i waited until almost last to do her's and it was hard as crap...i thought i was gonna throw the controller through the television. Many tries later, it was beaten, and then an idiot came in and reset konquest!!! So we had to do it all over again and i was the only one that could beat her. At any rate, God bless <><

i have 216 missions done but i can't get sparky done on raidens style branch combo

drahmin i couldnt do the test your might thing but it let me through anywayz... never could figure out why though

Bug i reckon, the game thinks it's a normal test your might so it just carries on!
I left Dhramin till last and so found his mirror match really tough!, he may not be pretty but he hits you hard!
other wise i remember getting really angry at a c ouple of peoples style branches when they just wouldn't work, *Cough!* Blame the tools i say! Anyway i think it was Frost and maybe reptile, can't remember!

I cant get past raiden's style branch part, one of cyrax's took forever to beat, and so did reptile's zaterrorize, plus mavado and sonya's mirror matches.

I had trouble with a few people where it demanded some really hard style branch combos.. also Movado's was hard sonya killed me a couple times or 10 :P

everyone else was easy but in my opinion Raiden was the hardest it took me while to beat it.

the cyrax combo where you have to launch him and then get him with the spin kick on the way down frustrated the hell out of me. i also left fighting jax and reptile til the very end, which was a mistake. rayden's combos weren't very hard for me, but one of his style branches is a little picky about the timing on one of the attacks. my advice with konquest is to save characters you like more for the end, because the mirror matches get progressively harder and you'll be better at fighting them with a character you like and are good with.

So far I ́ve had the most trouble with Johnny Cage ́s mirror match. Mavado ́s fight with Sonya was tough at first, but once I got the hang of it I had no problems with her, Jax or Kenshi. Admittedly, I haven ́t got Raiden or Cyrax yet, but I have lots of work and can ́t play as often as I ́d like to

i found the whole thing fairly easy, except for cyraxs combo where you knock em into the air and then use the spin kicks to hit em on the way down, that took 2 or 3 tries... johnny cages mirror match was definitely the hardest, but i still beat him first go.. the rest i did fairly well. oh and i couldnt break the diamond with drahmin, hell i cant even break the iron hehe! any tips for breaking iron?

Tips for braking Iron:
1. Be me, or someone like me.
2. If that doesn't work, get a turbo controller.

Oh yeh, I have to say I'm on GC for this, and I knew going into it that putting change style on an analogue button would be shit, so I've got it on Z, with Block on L and special on R. Works great for me.

jaxs mirror match and frost style change i still cant beat those two

Probably Cyrax, but after a while they all get easy. I've finished and started konquest mode about 4 times now. It's good practice.

Cyrax's was tough, but Raiden's was hardest....cracked it after about 15 mins of trying. The hardest mirror match was Jonny Cage, cos he's so cheap (damn sidestepping EVERYTIME you try and attack him). I found the rest easy!
