With high heeled boots, a 6’10” stature (with those heels), long hair, and some well-applied makeup, one might have trouble determining Rosie’s gender before they figure out his status as a Nomad. His skin tone is a light bronze, while his eyes are a clear shade of hazel. His clothes never seem to stray from grays and blacks, never hitting a true white or any flashier colors. He has that confident, satisfied look in his eye, and the way he proudly walks around with one hand on his hip and another on the straps of his tote bag seem to give the impression that he knows what he’s doing and what he’s after, even when he really doesn’t. His right eye is constantly covered by his thick brown hair, and he’s somewhat protective of whatever might be lying under it. He speaks in a rather flamboyant manner, and though little phases someone as old as him, he often shifts his tone in irritating, condescending ways when he wishes to mock someone.

A very, very long time ago, Rosier was an angel. He likes to say that he was a pretty important one, too. When he's asked about why he isn't one anymore, his answer often changes. Sometimes he says that he was a little too zealous. Sometimes he answers that he simply got bored, or that being a perfect embodiment of light and good was too stressful.

Regardless, he was a demon from that point on, a creature of lust and temptation. He enjoyed his job for the most part, though for whatever reason, he sometimes felt like his heart just wasn't in it. It was only around the mid-1940’s when he really began to realize his true calling: Art. There was something that struck him about Earth’s natural beauty. It wasn’t eternally perfect like in his first home, nor was it eternally tarnished like in his second. It was varied, fleeting, and somewhere in between the two extremes. It was something he felt deserved to captured.

He began to travel across the world, painting whatever he found to be worth painting, and making a quick buck selling whatever he thought was worth sharing. While it was something of an odd set of decades for the devil, it was very much fulfilling, and he never stopped travelling regardless of what friends or foes he made along the way. He was going to capture as much of the world as he could behind a canvas.

As well as brush up on his combat skills. Heavens knew there were plenty of roadblocks on his travels.

Rosie has some dextrous, delicate hands, and he prefers not to get them dirty on those lesser Nomads. His palette knife is actually the sealed form of his long-cherished greatsword, Rembrandt, and by coating it in shadow, he can project a sharp blade similar to a real knife. He uses it in up-close encounters, with a style that’s a fine blend between Scherma di Stiletto Siciliano, Esgrima Criolla, and Fairbairn-Sykes. He’ll deftly dance around and counter blows as well as wrap his scarf or coat around his hand and use it to parry other lighter attacks, grabbing opponents and stabbing them where it hurts if he’s feeling particularly sadistic. If a bit more range and power is needed, he’ll put his legs to work with deadly ballerina-esque twirls as well as roundhouses, butterfly kicks, and axe kicks, coating his boots in shadow to turn them into almost literal stiletto heels.

At range, using his paintbrush, he can leave ink in midair that can be used to make what he paints reality. With much room for creativity and stylistic flair, it’s his preferred method of fighting by a long shot.

He can also gather the darkness, chaos, aggression, and similar concepts of his opponents to store and use for his BlackStar transformation, returning both him and his greatsword to their true shadowy forms as he dusts off his fast and brutal demonic fighting style.

Rosie fights only decently at close range and excels at longer ranges, but falters at medium ranges where Cross Section is the only attack with the lack of setup time he needs to be effective. Anyone with the luxury of fighting comfortably in that range can shut down his ability to fight back if they can keep up with his attempts to move out of it. In BlackStar form, the same concept applies to long-range combat while he covers his mid-range weaknesses.

All of his paintbrush attacks are based on his own perception. If his vision is impaired, they become useless even if “aimed” correctly.

Though he is immortal, Rosie needs strength to maintain his physical form, and it can be dispersed if he takes enough of a beating. At least, until he can gather enough darkness to remake it, though that could take a very long time. Though decent, his endurance is nothing special, and he is especially vulnerable to holy and light-based attacks.

Rosie rarely treats his opponents as anything more than a nuisance, often viewing the challenges of those lesser beings as something not worth his time. When he begins taking his opponent seriously, they may easily have the advantage over him.

Rosie donates a fair portion of the money he makes through selling art to various environmental protection and preservation organizations, though most of that goes into landscape preservation.
