Across the DC and Marvel Universes and Harry Potter: A Genius's Heart Palpitations

Ciel Wayne Gaunt: the missing heir of the Bat Family and a descendant of Slytherin. He possesses a superhumanly brilliant mind capable of seeing through the truth at a glance, but suffers from a mild heart valve murmur. Every bout of intense deduction puts his heartbeat at risk. The "heart-strengthening potion" he developed himself is both the metronome keeping him alive and an economic bomb capable of uniting magic and technology.

From becoming top of his year at Hogwarts to chairing the United Nations Magical Council, he uses "heart-rate diplomacy" to tear up the Statute of Secrecy, defeats the old pure-blood establishment through patent monopolies, and judges global politics with the beat of his heart.

The thrills: unmasking secret identities in a second, heart-rate voting, turning the tables with patents, and reaching godhood with zero stamina
