Striker is fairly tall, even rivaling Blitzø in height and seems to possess a draconic/lizard like face with a gold tooth in his mouth. He has faded red skin, bright yellow eyes, a small black mustache, has white hair with a pair of horns striped black and white. Though, Striker's horns point upward and his horn pattern is more jagged. His tail as 4 black stripes at the base, with 8 spines lined up on them, and one on his tail fork. Striker's attire resembles that of a southern cowboy, with a stereotypical brown sun hat and cowboy boots, along with a light red scarf around his neck. He wears a black shirt having a dark navy vest, on top is a light gray jacket having black cuffs, his pants which are also light gray are shown to be ripped by his thighs. Striker is also commonly seen holding a straw of wheat in his mouth.
Like many Imps, Striker's eyes emit a light glow in dark areas.
Like how Blitzø can purr, Striker can create a noise similar to a snake or crocodile hiss. However, it's unknown if this is part of his unique anatomy or Imps can naturally hiss. When Striker moves his tail a certain way, it makes a rattling sound, similar to a rattlesnake.
He is the only Imp so far to have a spiral pattern accompanying the pupils of his eyes. He seems to possess reptilian-like features and traits such as creating crocodilian/rattlesnake sounds and possesses a reptilian snout like facial features opposing to the other Imps.

Striker is an arrogant individual who sees himself as superior to most of his kind and does not hesitate to mock and belittle those who are physically weaker, as shown how he constantly humiliated Moxxie due to his meek personality and lack of physical strength. Due to his pride, he deeply hates the nobility and bluebloods of Hell who treat his fellow Imps as a lesser class and gleefully takes the chance to kill higher classes of demons to prove himself superior, which can be seen on how he mocked Stolas when talking with Blitzø, clearly not caring that the two were close acquaintances.
He is very violent and ruthless to the point of being sadistic, which is demonstrated when he tried to kill Moxxie by strangling him when he discovered his blessing-tipped rifle to kill demon royalty and brutally broke Millie's arm when she stabbed him in the back numerous times in an attempt to save her husband, to later lock them in the house's basement and stating that he would kill them if it wasn't because they "didn't worth the cleanup", showing a great level of despise towards them. He even went as far to kick a girl in the face just for getting too close to him when he was singing in the festival.
However, despite his arrogance and violence, he has shown to respect those willing to do things even when the odds are stacked against them, which was demonstrated when he admired that Blitzø was able to start a killing business by stating that not many Imps were able to do so. He is also respectful to whoever he works with like Stella and Joe (Millie's father), treating them in a much more formal way.
Striker is cunning and manipulative, as he was able to make Blitz lower his guard by psychologically abusing him; stating that he was working for lower classes that couldn't care less about him and wasting his great potential by limiting himself to be Stolas's sexual plaything when he could do much better than that, to subsequently suggest they work together.
Given his friendly approach towards Blitzø, his statement that they were superior to their kind, and clear disappointment for his rejection of his offer, it can be assumed Striker genuinely saw Blitzo as a good killing partner due to his great physical prowess, showing he's willing to work as a team with people he considers to have the same impressive abilities than him.
He was shown to be fearless, as he confidently killed a hog for dinner with a knife and was able to keep a cool head when Blitzø busted him trying to kill Stolas, even cornering the first in a wall despite he was pointing at his chest with a gun in very close distance. He appears to be ambitious as he has aspirations above being an assassin and seeks to use his job to gather powerful Sinner slaying weapons so that one day he can possibly rise to the level of Overlord.
As an assassin, he prefers close-range combat as most of his fights seen to date were hand-to-hand. However he is willing to use ranged weapons when needed, such as killing Stolas at sniper distance.
