Who's Karosa? Where is Karosa referenced?

Karosa is mentioned by a tarkatan in the tarkata camp (G-5) in outworld

dude, Kochal doesn't exist. that's just the thing that lets u travel between realms again. after beating kobra, kabal and kira right ? ( KKK? LOL)
not an unlockable my friend. for super unlockables we;ll just have jax, quan chi, shang tsung, sonya and cage. maybe more, but these are very probable since they already have the bots for them and they're not 100% like they were in deadly alliance ( only 92% ) .

They are only about 80% of what they should be for unlockable's. They are just in the game for filler not to unlock. I have the krypt totally done, not sure what to do next. Have to do some checking on Kochal and Karosa I suppose.

find motaro.. I saw several reference about an army of four legged creatures.... hmmm extermination squad? hehe

Kochal is definitely NOT an unlockable character...it just helps you get Noob-Smoke...and a whole lotta onyx coins if you already got him.
I do not believe there to be any 'super unlockable' specific characters, I think when Ed Boon mentioned super unlockable, he meant 'hard as hell to find' ala Liu Kang...especially his alternate costume.
BTW...has anyone heard of anyone finding his ghost costume? I fought it at the Shaolin temple, but thats it...and it was bad ass...I want it...
Anyways...I think if you have unlocked all the characters at the select screen, those are all the characters you can play as in vs/arcade/practice. The only things left are alternate costumes, and then finito...maybe...hopefully I am wrong, but I doubt it...and personally, I think having Jax/Sonya/Kung Lao as 'super unlockable' characters would be lame, and not worth the effort....but thats prolly 'cause Im an avid Ermac/NoobSmoke/Jade fan.

I am at least hoping Quan Chi is in it, mainly because I am hoping they gave him a decent fatality to make up for DAs! Come on, the guy needs redemption after that!

I didn't believe in Kochal until after I did the portal, I heard his name mentioned again by an oni. After I struck the oni he said "Rarrr! Kochal will hear about this!"

Maybe they arnt SU's, they could be brought up now for a future game, who knows, I do however believe there are still atleast two characters hidden regardless of the main grid being filled or not. Now if I-Guides and Brady Games would update their site we could start working on it a bit more.

well yeah its looking that way. but seriously DA had two crappy super unlokcbles. and boon has mentioned there will be more than 24 ppl. so id expect at least 2, possible 4 but hoping for 6. depends on how it would be on the select screen since it was said they would be added to the screen after unlocked.could be 3 on each side vertically making 6 or even those four little dots above jade, kenshi, sindel and havik having something to do with it. time will tell.

its not the ghost one, you cant use it, I unlocked his alternet, its just .... plain.... liu

hmm... someone mentioned the 4 black dots on the character select screen so I examined it a little more. On the sides of the screen there are 6 tabs sticking out, 3 on each side. 2 of the tabs come out, one for entering profile and one for changing handicap. Is the last one there to represent the level change, or is it something else?

Sounds interesting.
My guess is that there will be more secret characters. I had been told a long time ago:
Quan Chi
Sonya
Mavado
Kitana
Sektor
Sareena
Shang Tsung (not likely anymore, but possible)
I also think Johnny Cage has a chance if those do.

Well I'm in the UK and havent got the game yet, and haven't been reading many of the spoiler etc, but I still think Quan Chi, Kitana, Fujin and Sareena have the best chances of being SUper Unlockable.

You have to bring shinnok his amulet too, and 1 more thing I forget...

the 3rd tab is for waging money when you play against a friend, it's written in the book

Yep
