Stakch is a 5'9" thin skaven (ratfolk from Warhammer) with rich brown fur and tanner fur on his chest as well as a few white patches for his eyebrows, right shoulder, and a little bit of chest fluff. There is a long scar from his left shoulder to his right thigh from an old sword wound he suffered from an underling attempting to move up (Worry not, that underling has since been "dealt with"), he also suffered from a bite to his right shoulder that left a scar behind. As is common among his people, his nose area is free of fur with a pink flesh instead along with the tail, hands, and paws. He also proudly sports a crimson tattoo of the cursed triangle, the unifying mark of the Skaven Under-Empire. He has five fingers and toes and his eyes, unlike most skaven, are a brilliant orange color with a red pupil.
His clothing primarily consists of well-worn shirts and shorts that he's gathered from various enemies and, as is the nature of all skaven, slapped the cursed triangle on the back of all of his shirts. As a member of Clan Moulder, and a packmaster in his own right, he wields a whip iconic of all packmasters and has pouches on his belt filled with all manner of insidious devices to aid in his daily life, including a sewing kit, syringes of poison or potions, and more.
For combat, he wields a halberd taken from a fallen Stormvermin and various pieces of armor he's patched together from enemies and often a bandolier of primarily-aerosolized vials containing a variety of poisons or transformative concoctions. He also wields a warplock pistol, a miniaturized version of the warplock jezzail.
