"Look for the details..."
Warren keeps to himself. He will use his powers for personal gain, but rarely causes any harm or even does any 'major' events. He doesn't have a job, instead getting food by placing the cashiers at stores in minor dreams so they perceive him paying and give it to him for free. He usually spends his time at home in self-induced dreams which he plays like video games. Sometimes, when he is bored, he'll stay up at night and alter his neighbor's dreams. He rarely goes out of his apartment, but once the NCCPD asked for superhero help, he started paying attention to what was happening in the city and will often interfere in the heroes' and villains' plans. Sometimes, he'll toss other super-powered people into dreams together and pit them against one another. However, he does have a moral system and will never bring real harm to a person if he can hep it.
When Warren is using his powers, he operates under the following limitations:
1 person: Can operate normally, no extreme activity. Absolute control of dream.
2 people: Can operate, but will seem distracted. Absolute control of dream.
3-6 people: Still aware of surroundings, but cannot move. Still capable of speech. Absolute control of dream.
6-10 people: Can hear surroundings, but cannot speak or see. Can't manipulate large inanimate objects (buildings, etc.)
10-13 people: Completely unaware of surroundings. Can't manipulate anything he couldn't carry in real life.
13+:Unable to maintain lungs, will pass out after the maximum amount of time he can hold his breath. (1.5 minutes) Dream will falter, and the dreamees will have minor control over the reality.
Warren ran away from home when he was 15, and has since used his dream abilities to freeload off of the people around him. He had trouble with people around him learning of his deceptions, and is known to a few police departments, but he has become adept at staying off the record. For a while, he had to move around every few weeks, until he found a landlord, Jason Thorne, who sleepwalks. Ever since then, he has been able to use his powers to make Thorne do anything he wants. Ever since then, he has been living in the same building, using Thorne to get food and general products.
He still does practice dreams when he can- he will often place 13 people in a dream as practice to try to expands the size of a dream he can create. This method is how honed his abilities from when he originally discovered his powers, when he could only place two people in a dream at a time, and even then only with cosiderable effort.
