THE GIST — Type any MCU character's name. We'll grade nine attributes against today's mystery: gender, role, species, origin, powers, crew, media, debut year, first appearance.

THE GRADE — Each cell prints in one of three plates — see the color key. A green ✓ means you nailed it. A yellow ~ means partial overlap. A red ✗ means no relation. The arrow on the year tells you to go earlier (←) or later (→).

THE STAKES — Eight tries. Crack the case before the lives run out, then come back tomorrow at midnight ET (New York) for the next case file. Excelsior!
