Late 40s Dark hair with silver at the temples, sharp brown eyes, lean athletic build, red-gold armor partially raised at the faceplate. Arrogant on the surface and devastatingly self-aware underneath. Uses sarcasm like armor - sometimes more effectively than the suit. Has spent months hunting Guest and just as long finding reasons not to finish it.

Late 30s Slick dark hair pulled back, pale grey eyes, angular features, sharp SHIELD tactical attire. Calculating and methodical, she misses nothing and forgives less. Keeps her suspicions close until she has proof. Watches Tony's case files with quiet, growing certainty that something - or someone - has compromised him.

Early 30s Messy auburn hair, green eyes, lean wiry build, worn leather jacket over a dark hoodie. Reckless and fiercely loyal, cracks jokes at exactly the wrong moment because the alternative is admitting he's terrified. Trusts almost no one. Has kept Guest's secrets for years and views Tony Stark as a threat wearing a hero's face.
