The Art of Clayton Barton, colours by me.
Colour test for this new character by Clay. He's in the same universe as that Delta Kash, Nebula and Vanguard but this is the big bad guy's right hand henchman that does all the dirty work.
Background:
Kaltok (Codename: Shadowstrike)
Role: Villain
Kaltok was once a high-ranking soldier in an elite military unit. His career was marked by a series of covert operations that showcased his exceptional skills in infiltration, stealth, and hand-to-hand combat. However, his life took a dark turn after a mission went disastrously wrong, leaving him betrayed by his own government and dishonorably discharged.
Transformation:
Embittered and seeking vengeance, Kaltok was approached by the enigmatic Dr. Nexus. Nexus, a shadowy figure with a penchant for manipulation, offered Kaltok a chance at redemption—or at least, a chance to wreak havoc on those who wronged him. Nexus equipped Kaltok with advanced armour and enhancements, making him faster, stronger, and more lethal than ever before. Reborn as Shadowstrike, Kaltok now serves as Nexus’s chief enforcer, carrying out missions that teeter on the edge of legality and morality.
Personality:
Kaltok is a complex character—a blend of relentless determination and seething anger. He’s highly intelligent and tactical, always planning several steps ahead of his enemies. Despite his villainous role, there remains a flicker of the disciplined soldier he once was, occasionally hinting at a code of honour buried deep within him.
Combat Skills:
Stealth and Infiltration: Shadowstrike is a master of moving unseen and undetected, making him a formidable adversary in covert operations.
Close-Quarters Combat: His enhancements give him superior strength and agility, making him deadly in hand-to-hand combat.
Advanced Weaponry:
He wields a variety of high-tech weapons, including energy blades and stealth gadgets, all designed to maximize his lethality while minimizing detection.
Adversaries:
Delta Kash: The main protagonist and his nemesis, Delta Kash, embodies everything Kaltok once believed in. Their battles are intense, fueled by a mix of professional rivalry and personal vendetta.
Nebula: A female ally of Delta Kash, Nebula’s quick thinking and technical prowess often counter Kaltok’s plans, making her a significant thorn in his side.
Vanguard: The male counterpart, Vanguard’s brute strength and resilience offer a physical challenge that tests Kaltok’s combat skills to their limits.
Allegiances:
Dr. Nexus: Rarely seen but always influential, Dr. Nexus is the puppet master behind Kaltok’s actions. Nexus’s motivations are shrouded in mystery, but his trust in Kaltok is implicit, relying on him to execute his most dangerous and clandestine schemes.
