Yes, Carlo looks like Kyuss [link]
Thats because Carlo IS Kyuss.
Carlo is a Kyuss that ended up on a completely different road in life. Carlo is a Kyuss who actually died in the lab rather than survived, and was brought back in the form you see him here, seemingly with no recollection of his previous life, though he still harbours frost-bitten ears, finger tips, and tail tip.

Unsurprisingly, this is only a stage name, but for all intents and purposes, it is his real name as its what everyone calls him.

Carlo is a chain-smoking, californian rock musician from an undefined era who entertains in the underground clubs in chicago, and deals drugs on the side.

Although unknown to most residents of the city, Carlo is a supernatural being.
Those who know him well or have had a lot to do with him claim him to be some kind of 'angel', but Carlo shrugs off this notion, presumably because being labelled an 'angel' would play havoc with his bad-boy image.

However, in all likelyhood, this is what he is.

The full extent of his powers is not known, perhaps even to him, but he has demonstrated the ability to appear and disappear at will, the ability to conjour up objects from nowhere (particularly used for cigarettes and joints), and even the ability to change the appearance of certain things around him.
He seems to radiate a glow when hes baked, or when he has drugs to sell you.
In general, this is green for weed, red for speed/amphetamines, purple for LSD, brown for shrooms, and white for coke. If combined, or the drug is unspecific, it is blue.
Only those who are also stoned seem to be able to see it.

He displays a number of theatrical abilities during his gigs, from making his eyes glow, to making his bones show through his skin. However, most think of this as simply some kind of technological trickery and he is rarely confronted about it. This is because many people do not realise what he truely is, and simply view him as another flesh and blood resident of the city, albeit a slightly strange one. His clothing and music style are unique in 1920s chicago and unheard of elsewhere in that time period, and he is frequently labelled as simply 'ahead of his time'.

Carlo is a well known character in the city, and all the long term residents know him, or at least know OF him. That doesn't mean to say he is necessarily popular.
Due to his druggy ways, and general love of rebellion, he is wanted by several law enforcement groups, but he consistantly evades capture, almost to the point where it's become a joke.
Even the police are dubious as to whether he will ever be caught.

He sometimes turns up in places he knows the police will be, seemingly just to mock them with his mere presence. He has a habit of appearing from nowhere to taunt them, often sitting nonchelantly on a wall or table, smoking (as always)
He enjoys goading the police into rages, and the whole thing seems to be a big game for him. He is almost child-like in his love of mischief and chaos.

It is not known for certain whether he is able to be harmed by earthly things such as bullets or knives, but in all likelyhood, he can at least be injured by these as he tends to make a quick exit whenever guns are shown, and he has been seen to bleed in the past but no one is sure if this is another piece of trickery he employs to make others think he is a mere mortal.
To law enforcement, he comes across as infuriatingly arrogant, but Carlo believes that an omnipotent angel has the right to be arrogant!

He is ordered around by his head angel, a rat called Boots, who does not live on earth but appears from time to time to check on Carlo.

Men and law enforcement claim he is completely untrustworthy, a really bad character to get involved with, and no man worth his salt would ever let their woman spend any time around him. He is seen as trouble, a rogue and a criminal. A whole plethora of stories and urban myths exist about him, and Carlo never denies them. Its likely that this is, once again, a way of personally amusing himself by watching everyone around him react.

However, virtually every female in the city swoons over him.
Women look at him like they're starving, become fixated on him if they see him in the street, and turn into googly-eyed zombies if he speaks to them. And Carlo plays on it, extremely heavily. His gigs attract crowds of doe-eyed girls, and Carlo couldn't be happier with that arrangement. The general air of other-worldlyness and mystery that hangs around him seems to be irresistable.

Carlo loves the nightlife, and is strictly nocturnal. He lives underneath the Orchid Lounge, the club he often performs in, and is the number one supplier of illegal substances in the city. Despite all the rumours and gossip that surround him, he is actually not a particularly dangerous or intimidating character once you get to know him. He simply wants to have a good time, wants everyone else to have a good time, and sees authority as a barrier to this.

He tends to be mainly non-violent and easy going, but he does get into the occasional bar brawl with guys who wanna show off to their friends by attempting to start trouble with him. As he is such a well known figure with a reputation for rebellion and law breaking, drunken men are eager to try and prove that they are tough enough to bring him down.
They never try it twice.
Although Carlo refuses to use his powers seriously in crowded places like bars, he doesn't need them to win a fight. He is a huge rat, and he has a typical fiery red-head streak. Though he insists that fighting is simply a way of venting, and he is happy to assist people in their need for venting.

He has a wonderfully dry, sarcastic sense of humour and a very confident, self assured air. He oozes charisma, charm and sex appeal.

For clothing, he loves red plaid, denim, and pocket bandanas. He is somewhat influenced by the 1950's Greaser look [link]
He is a chain smoker.

Apologies for the huge size of these refs, but its hard to get the detail in on anything smaller.
