On chaos you should pick your team carefully after their and your abilities. A good team is vital.
Each character has an advantage as well as a disadvantage, when facing Orochi.
Some characters (actually all) is capable of soloing Orochi on chaos.
Explenation:
S = Square
T = Triangle
R1 ( R1 ) = Special
SSsT is Square, square, square, triangle, for example
I'll try to list the characters their abilities against Orochi... If you wonder weather the ones you'd like is good or not. Look bellow.
Wei---
Cao CaoCao Cao is a medium strong character with decent move set, strength, defence and agility. Cao Cao can cover a complete area around him, and taking down Orochi isn't all that hard with him.
Advantages:
Cao Caos charge attacks are strong and fast, and he do quite quick slashes too. Cao Caos SSSST and SSSSST(TT) is some of the most effective attacks against Orochi. Cao Cao can easily slip away from Orochi, and by jump charging through the crowd, he can clear an area for fighting against Orochi.
Disadvantages:
Theres not really much to say about Cao Cao. He is a light hitter which means that a normal guard can hit him out of rhythm. Cao Cao should also watch not to get to close to Orochi, as he can easily get captured in a combo spree with loads of troops and Orochi. Other than that it isn't really much to say. Cao Cao is sometimes open at his back at some attacks, be cautious.
---
Cao PiCao Pis strength isn't that all great, neither his agility. Cao Pi has an advantage of his range though which do make him vary useful. Cao Pi is one of the characters that moves longest during a full combo, this means that he can tear through a crowd of enemies and end up charging right at Orochi.
Advantages:
Cao Pis advantage is as mentioned above his range and movement. Cao Pi has his jump charge as a pretty decent attack too, it does heavy damage and captures Orochi completely. Cao Pi can do ranged attacks. Cao Pi can take good use of his technique style, as countering (R1 button after being attacked) can clear away some annoying enemies.
Disadvantages:
Cao Pi have problems covering his back, and does also have a slight spacing between his attacks. A long charge time makes it hard to do a complete combo so remember to have the counter ready. Do not try to do the longest attacks SSSST and SSSSS(R1) if you are close to Orochi, if you want to use them, start the combo from a distance.
---
Cao RenCao Ren is a powerhouse, and with his strength and defence he make a deadly foo against Orochi. Cao Ren is small in size and most of his attacks breaks guards and charges through enemies. Remember to counter allot with Cao Ren, doing this will make it easier to stay in the battle. His musou bar shouldn't be used for anything else than countering and S(R1).
Advantages:
Cao Ren has a big advantage over Orochi, all of his attacks are easy too perform and can be done without any involvement from enemies. Cao Ren can easily break Orochis tight guard and at the same time take down surrounding enemies.
Disadvantages:
Cao Ren is very slow, and if dealt a vital blow, the chances of getting away is low. Cao Ren has a small weakness for archers as well as they can knock him over during his long charge time. Cao Ren also has low range on his normal poundings (S attacks) which means that most attacks will miss.
---
Dian WeiDian Wei, the warrior which can do heavy damage to Orochi, at range! Dian Wei is yet another technique character, but unlike Cao Ren and Cao Pi, Dian Wei don't need his counter.
Advantages:
Dian Wei is very strong, as strong as Huang Gai. Which means he matches Orochi. Dian Wei can throw his axe very far, this allows him to clear an area of surrounding troops and go right for Orochi. Also, Dian Wei has one of the most power full R1 specials in the game. the two explosions does high heavy damage, and by using as many as your musou bar allows you to, Orochi should be down very fast.
Disadvantages:
Dian Weis speed and spacing can be a very big issue sometimes. The longer attacks are hard to do, so you should stick with the simple ones. Also, Dian Wei has a low close-up range, so you should be very care full with how you attack. His back is always open.
---
Pang DeYet another WEI power house. Pang De can juggle the enemies, even though his move set and attack speed is very slow. Pang De have a unique strength and his defence is decent. He can take down Orochi really fast
Advantages:
Simply good. Pang De has a good range and covers a complete 360 degree around him. Aswell as his power type push back the enemy, it also mostly stuns them. Pang De has some spacing and gaps, but his Push-away ability makes up for it. Pang De do not need to use his R1 special at all. Pang Des jump charge is good for getting in and out of crowds.
Disadvantages:
A small disadvantage with Pang De is his swinging, after a simple square attack, Pang De uses some time to get his halberds swung forward again. This means that Orochi can sneak a strong attack in between these gaps. Pang De is a very good crowd controller, but if you don't focus on Orochi directly he might fall quite quickly. Pang De also has the small disadvantage of his charge times, they serve as no issue towards troops, but again, Orochi may hit you hard during this small amount of time.
---
Sima YiA good equal to Cao Cao and Cao Pi, fast, with decent range and moveset. He do not need the same tactics as Zhou Yu and Zhuge Liang as he strongly surpass their moveset. But both Zhuge Liang and Zhou Yu can take abit more of a beating than Sima Yi, there's where his biggest weakness is.
Advantages:
Sima Yi has the advantage of speed. He can escape with ease and come back again just as fast. Sima Yi can attack from a distance as well as doing heavy damage at close range. His R1 specials are good for homing and crowd clearing properties. Sima Yis SSST(T) serves as a major crowd controller and can clear the area arround Orochi fast.
Disadvantages:
Sima Yi is low on strength and thus his attacks have very little effect. Sima Yi doesn't cover his back in any of his attacks either so face-to-face close-up battle is very risky. Sima Yi is easily juggled as he's a light hitter (means that he gets easily knocked over during attacks).
---
Xiahou DunXiahou Dun is yet another one that can go hand in hand with Cao Cao, Cao Pi and Sima Yi. He is a light hitter, has quick attacks, little spacing, can start attacking from a distance and has low cover at his back. What's so special about Xiahou Dun is his ability to stay in a one-on-one combat without getting distracted by troops.
Advantages:
Xiahou Dun is fast and strong. His R1 specials serves as the distance attacks and he can draw the enemies in with it. Xiahou Dun moves through the crowds at almost the same speed as Cao Pi which means that he can clear a crowd before getting a strong hit from Orochi. Xiahou Dun can take down Orochi by using his SSTTT and jump charge.
Disadvantages:
Xiahou Dun is like all other speed types, his attacks are easy to block, and he can easily be pounced out of rhythm. Xiahou Dun isn't easily juggled but instead, by some reason, he can be sent flying away quite easily. Xiahou Dun has a slight spacing in his attacks which can be a thorn in his side.
---
Xiahou YuanThe archer with the strong attacks. He is very much the same as Huang Zhong, but unlike him Xiahou Yuan can manage a close-up battle. Xiahou Yuan has a good strength as well as his speed isn't all that disappointing.
Advantages:
Xiahou Yuan has many shock waves in his moveset, and his R1 special covers a large area infront of him. His moveset is easy to get used to as it is of the same type as Huang Zhong. Xiahou Yuan has a strength in his ability to survive arrows and do some very impressive turns.
Disadvantages:
Xiahou Yuan can't cover his back under any circumstances, he has a slow going moveset, low range and on some occasions he easily miss the target. His arrows are mostly point less as they have no effects on Orochi.

Xu HuangXu Huang, strong, fast and technique style

. Xu Huang is a great start character indeed. He is quite good against Orochi in fact, and has almost no disadvantages worth noticing.
Advantages:
Xu Huangs advantages is:
- His moveset covers all the way around him, always!
- He can counter attacks, which covers for the gaps.
- Xu Huang has many spins, but at the same time he isn't stationed. This means that he can take down enemies around him as he is moving forward.
- he can easily get to the hardest attacks to perform for some characters, the SSSST and SSSSST.
- Xu Huang can take down Orochi and keep enemies at bay.
- Not easily hit by enemies.
- Does some very great damage!
Disadvantages:
There's almost no bad things about Xu Huang. Even so I will mind you that he isn't the best. You still have to be very cautious when you attack Orochi. Xu Huang has a little disadvantage in his disability to get stuck when trying to get away. If you reach a critical health level pull back immediately, Xu Huang is not the kind of character you keep going with. Do not jump charge to get away, it covers only a small area and you can easily get critically damaged if you get knocked down.
---
Xu ZhuThe good old panda man Xu Zhu. He has a couple of good attacks even though he is slow as a turtle. Xu Zhu is not the character to stay long against Orochi though, he can get some troubles with his Power type mixed with some heavy Orochi life drain.
Greatest defence in the game mind you, serves as a good shield against Orochi and his troops.
Advantages:
Can send enemies flying away and clear areas fast. nothing else really remarkable. His R1 special is very good against Orochi though.
Disadvantages:
Not really much here either, as he can take a couple of poundings, and his spacing isn't really a disadvantage to him. He pushes back the enemy in each hit so the gaps shouldn't be a problem. The only issue is his speed, he will have very big troubles trying to get away from Orochi, so start retreating a good time in advance. Very stationed.
---
Zhang HeAnother speed character, but very unique from the rest. Zhang He covers a huge area, he is very agile, does some pretty jiffy damage and he is "elegant". Zhang He is one of the most unique speed characters in the game. He is not the best even so.
Advantages:
Zhang He covers a large area, and enemies behind him is no big issue as he moves forward alot. Zhang He has a lot of straight forward charge attacks where he simply dashes through the enemy. He has almost no spacing and his charge time is like it doesn't really exist.
Disadvantages:
Zhang He is a light hitter and is easy to block (notice: Equip Flash). Zhang He also has a small disorientation in his attacks and is hard to control during his fastest attacks, this means that he miss a lot. Zhang He have some stationed charge attacks which are
very stationed, this makes an opening for Orochi, so remember to be focused on him during these attacks (SSTTT, SSSST and SSSSST).
---
Zhang LiaoZhang Liao, Guan Yu and Lu Meng. What do they have in common? Let me tell you: Strength, charges, defence, range, moveset and turns. Zhang Liao is not the same character as Guan Yu and Lu Meng, but they all do the same thing against Orochi: Leave him without troops!
Advantages:
Zhang Liao has a very good range and his attacks are very good. He covers a surrounding circle around him, and only have gaps in his charges (this is opposite with Guan Yu). His move set is equal to Lu Mengs and is easy to get used too. Zhang Liao has a smooth attack pattern wich makes him easy to control. The first charge (T) makes it possible to charge right through the enemy crowd and go straight on Orochi. His R1 special is quite good against charging enemies (including Orochi).
Disadvantages:
Zhang Liao is having some escape issues wich can be quite annoying. Also, Zhang Liaos charges, which are the most effective against Orochi, have a long charge time and have a lot of open gaps.
---
Zhen JiThe speed type beauty Zhen Ji and her magical flute. Zhen Ji lacks agility, range, strength and defence, and may be counted as the worst character by the first look. But Zhen Ji have some very evil tricks up her sleeve, so you should not underestemate her.
Advantages:
Zhen Ji is very direct, but at the same time she can cover a very small area around her. By going straight on Orochi she can do some very bad damage by using her ST, SSTTT and SSSTTT. If used properly, each of those attacks leaves time to attack the crowd. But, this is where Zhen Jis true strength lies, Zhen Ji has a very naughty forward R1 special wich makes the enemies go in slow motion, even Orochi. This is what gives her enough time to keep the enemies at bay.
Disadvantages:
zhen Ji has low defence and health, this means that if she gets hurt she may die immediately. Zhen Jis R1 special is a very risky jump if you are in a crows, as if you get hit the effect is automatically removed. Zhen Ji is full of spacing and gaps, even infront of her, this means that she is the only character that is open for all attacks, from all directions.

I hope this guide helped! If you have any questions about the ideal team or any other matter, you can PM me or ask in the forums.---
And as a quick end notice to cover some confusion.
The difference between gaps and spacing. Spacing is the time between the attacks, this is for example when the next square button is reliesed or when you perform a charge attack. Gaps are holes in the attack itself which allows an unwanted attack from another direction, for example an uppercut. And uppercut hits straight in front and uppwards, during an uppercut and attack from either of the sides is unblocked. Hoped that cleared up the confusion
