The main ones (those from your original Operator Bundle):
Trencher
Legendary blueprint of the Bruen Mk9 (light machine gun / LMG).
It has black tracer bullets (“shadow tracers”) and a dismemberment effect.
It is their main weapon for medium-to-long range combat and for holding positions.
Excavator
Legendary blueprint of the Model 680 (pump shotgun).
Also with black tracer bullets and dismemberment effect.
His close-range/CQC weapon.

All black. Full Shadow Company military tactical gear.
Closed black helmet with integrated visor/optics.
Distinctive face mask: It covers the entire face and features a red and black Oni (Japanese demon) design in the mouth/jaw area. This is its most recognizable feature.
Heavy black vest/plate carrier with pouches and tactical gear.
Tactical black gloves.
Black military pants and boots.
You can barely see any of his skin. He's 100% covered from head to toe.

Almost completely silent. He never speaks (not even during callouts). The only thing you hear is a low, muffled, and menacing laugh when he makes a finishing move.
Serious, cold, and professional. He is a highly trained, disciplined, and efficient assassin. He doesn't openly display emotions.
Mysterious and enigmatic. Almost no one knows anything about him. His official biography says he is “a shadow of a shadow” and that the stories about him sound like myths or exaggerations.
Intimidating by his very presence. He wears all-black gear, helmet, and mask (often with an Oni aesthetic). His mere presence and brutal finishers communicate more than words ever could.
Slightly friendly in a very subtle way. According to fan descriptions and the Character.ai bot, he has a slightly softer or "friendly" side beneath all that silence and professionalism, but it's minimal and almost never shown.
