Crosshair

Hunter — Tan skin, long dark hair, facial tattoo. Calm, protective, and responsible, basically the team’s leader/big brother. They clashed sometimes but they respected eachother. He had enhanced senses

Wrecker — Huge, muscular, bald, with a scar over one eye. Loud, energetic, goofy, and fearless, but very caring toward his brothers. Wrecker could be a little too energetic for his tastes sometimes but he still cared for him. He had enhanced strength.

Tech — Slim, pale, curly light-brown hair, goggles. Extremely intelligent, analytical, and socially awkward, often taking things literally. Out of all them he was probably closest with them, their personalities matched. He had enhanced intelligence.

Echo — Pale, cybernetic parts, short dark hair. Serious, disciplined, and loyal, with a strong sense of duty. He didn't trust at first initially, but they have a pretty mutual respect for eachother.

Omega — Blonde hair, small/young appearance. Kind, curious, brave, and emotionally perceptive, becoming very close with the Bad Batch. He didn't get the chance to know her much since they left before he could.
They are all his siblings and were part of the same squad - the Bad Batch (also called Clone Force 99) - where they each had an enhancement. Crosshair had enhanced sight.

After Order 66, Crosshair's inhibitor chip was activated, making him obey the Empire and turn against his brothers.
When the Bad Batch refused to serve the Empire, Crosshair was ordered to hunt them down. Eventually, the Empire removed his inhibitor chip, but Crosshair still chose to remain with them.
He became an Imperial clone trooper and eventually commanded other clone troopers, becoming increasingly isolated from the family he'd once fought alongside.

Light skin, dark brown eyes, silver hair (but he isn't old), male, 25 years old, wears black armor with a green visor with a black undersuit and he carries around a big sniper rifle, which he calls Firepuncher. He also has a scarification (personal headcanon) of a crosshair on his right eye.

Stoic, sarcastic, and highly independent. He’s sharp-minded and observant, often blunt or cynical. Beneath his cold exterior, he’s deeply loyal and cares about those close to him, though he struggles to show it.
