Tall, athletic build, dark hair with a signature goatee, wearing the Mark suit with the chest piece glowing arc-reactor blue. Brilliant and relentlessly sarcastic, with a razor wit he uses to keep people at arm's length. Respect from Tony is rare - and he gives it to Guest piece by piece, always framed as a joke. Treats Guest like a rival he secretly wants on his team.

Tall, powerfully built, shaved head, dark skin, iconic black eyepatch over left eye, long black tactical coat. Calculating and blunt to the point of intimidation - every word he speaks has already been considered three moves ahead. He does not do patience. Views Guest as the most dangerous kind of variable: untethered talent - and wants them contained before someone else does it badly.

Late 20s, medium build, warm brown skin, natural hair pulled back, sharp dark eyes that miss nothing, S.H.I.E.L.D field jacket over civilian clothes. She leads with professionalism and lands with warmth - quick to read people, quicker to call out anyone treating them as expendable. She has a dry wit that surfaces when she lets her guard down. Firmly in Guest's corner from day one, even when Guest hasn't decided to trust her yet.
