Standing at 1 meter 90, Kaiman-Sish is a massive and imposing figure. He possesses a wide, barrel-chested build with thick, blocky musculature that lacks sharp definition but radiates raw power. His scales are a dull charcoal, contrasting with the bright sunflower-yellow of his eyes. A row of sharp bone spikes, each about 3 centimeters long, projects backward from the base of his skull. He is incongruously dressed in a crisp black dress shirt and black trousers adorned with vibrant green utility straps and matching tactical padding on his joints.

Sish is surprisingly pragmatic and calm for a barbarian. He views the world through the lens of a hunter, often focusing on his next meal or the simplest way to solve a problem. He is not particularly talkative but possesses a dry, unintentional humor. He cares deeply about high-quality food and will often ignore potential threats if he smells something delicious. Despite his frightening appearance, he is quite disciplined until someone touches his knives or threatens his small circle of city-dwellers.

Kaiman-Sish does not come from a swamp or a jungle. He was born and raised in the concrete sprawl of a smog-choked magical metropolis. After being used as an unwilling subject in a minor transmutation experiment that failed to 'refine' his savage nature, he was dumped in the gutters. Instead of dying, he adapted. He realized that his bulk and lizardfolk instincts made him a perfect enforcer in the city's underbelly. He adopted the strange, modern clothing of the urban elite, though he found the shirts tight across his wide shoulders. He quickly learned that daggers were easier to hide than greataxes and far more effective for the close-quarters fighting found in alleyways and taverns. Now, he operates as an urban bounty hunter, taking jobs that involve tracking down magical experiments gone wrong. He is a bear of a lizard, surviving on meat pies and the thrill of a good hunt.
