Alan Ladd Wellington Scott
Alfred Thaddeus Crane Pennyworth
TACTICAL VERDICT: Alan Scott triumphs with an estimated 72% win probability. The primary decider was the stark differential in martial combat execution (32 vs 55).
Both combatants exchange lightning opening volleys with near-identical operational reflexes, neither yielding ground in the opening clash.
Alan Scott unleashes full destructive capacity (100 Power rating), forcing Alfred Pennyworth onto the back foot with overwhelming concussive force.
In the grueling war of attrition, Alan Scott's supreme hand-to-hand discipline (32 Combat) and endurance (90 Durability) break Alfred Pennyworth's posture, securing a definitive victory.

Comics grow darker and more socially aware. Wolverine, Punisher, Swamp Thing debut. Creator-driven storytelling emerges.
Newsstand variants carry meaningful scarcity premiums. First appearances from this era are blue-chip investments.
Inspectable mathematical proof, blockchain/ledger provenance, data integrity validation, and asset taxonomy.
In illiquid alternative asset markets, sovereign blue-chip holdings trade at an exponential multiple over mid-grade float due to institutional accumulation and inelastic seller reservation prices.
Seth Gross, a wicked magician, befriends Vashnu, learns the secret of astral projection, and steals from him a mystic box with the power to trap a soul. He goes into ghost-form and uses the box on the daughter of scientist McJames, forcing him to attempt jewel robberies in return for the soul of the little girl, who will remain in suspended animation for some time. Johnny Double and the Challengers of the Unknown become involved in the case, but it is Deadman who actually fights Gross, inhabits his spirit-form in a particularly painful process, and restores the little girl's soul to her body in time. At that, Deadman exits Gross's ectoplasmic form, with Gross driven insane by the experience and unable to return to his body.
