**William Carmody** was a brilliant scientist, who developed a technological means of keeping the human brain alive indefinably after the human body failed to sustain it. In 1980, a group of terrorists working for the Ten Rings raided the S.H.I.E.L.D. facility Carmody was working at to steal Carmody's invention for themselves. During the raid, William was fatally shot and had his assistant Jim Fitzpatrick and the other S.H.I.E.L.D. scientists perform his brain transplant procedure, turning Carmody into the **Eternal Brain**.

## Biography

William Carmody was a brilliant biogeneticist who developed a means to keep organic brains alive after physical death, heavily building upon the decades-old secret work of Charles Lindbergh. In 1975, William Carmody was hired by SHIELD to work as a scientist on a project called Project Mi-Go, named after the alien fungi from a short story written by H. P. Lovecraft where the titular aliens plant living human brains in cylinders to transport them to other planets. Carmody managed to preserve the brains of a Rottweiler via an "artificial synthetic heart", and five years later, he and his assistant Jim Fitzpatrick prepared to adapt the technology for the benefit of humans. However, the Mandarin learned of their plans and sent agents of the Ten Rings to infiltrate the lab and steal the object, shooting Carmody in the process.

The dying Carmody instructed Fitzpatrick and the other scientists at S.H.I.E.L.D. on how to preserve his living brain, allowing him to survive as a sentient brain in a robotic body made from a Vibranium alloy which also contains what is called a telepathy receptor, which gives Carmody various mental powers. Calling himself the Eternal Brain, Carmody accompanies several S.H.I.E.L.D. agents via Quinjet to a stronghold of the Ten Rings located in Ashgabat, Turkmenistan. There, the Eternal Brain mentally induces the members of the terrorist ring to kill each other, and the team managed to retrieve the artificial heart. Eternal Brain's actions impress Alexander Pierce, the then-current Undersecretary of the World Security Council. Carmody was sent to Hawaii a few days later to join a team of paramilitary troopers called the First Line on their first mission, which was to protect the Spanish Embassy from angry indigenous peasants of the Committee for Peasant Unity and their allies in Guatemala City, Guatemala, on January 31st, 1980. Unfortunately, their first mission ended in massive failure as a fire caused by the police breaching the office door and introducing white phosphorus, which together with the Molotov cocktails ignited a fire that destroyed the embassy and left 36 people dead. The First Line was ordered to disband by Alexander Pierce and Carmody was assigned to lead a project in Antarctica to excavate a potential alien spaceship.

Many years later, Eternal Brain was still continuing his research on the spaceship when Steve Rogers, known as Captain America, announced to all of the agents and employees that S.H.I.E.L.D. has been infiltrated for years by the terrorist group known as HYDRA and urged them to stop the launching of the Helicarriers. Members of the research team who were members of HYDRA pulled out their weapons and held the rest of the research team hostage. However, the Eternal Brain used his telepathic powers to compel them to shoot each other instead and led the other members of his team to evacuate outside the bunker while the HYDRA agents shoot each other to death. Carmody and his research team were rescued on a Quinjet by Nick Fury, and the group was flown out of Antarctica. Carmody worked for the Central Intelligence Agency as an agent and scientist after S.H.I.E.L.D. was disbanded.

In the spring of 2018, the mad titan named Thanos used the Infinity Gauntlet to snap half of all life in the universe away. Carmody was one of the survivors of the event. However, his daughter Mary Carmody did not survive the event and was snapped away, leaving William Carmody in terrible grief. The Eternal Brain leads a group of researchers and scientists to find a way to bring those who have died from the event back to life, without much success. During these periods, the Eternal Brain worked together with renowned scientists such as Jane Foster and The Hulk and joined a newly reformed S.H.I.E.L.D. as lead researcher of Operation Mary, named after Carmody's daughter.

In 2023, despite great difficulty of wielding the Infinity Stones' raw power, Banner was able to snap his fingers and ultimately undo the Snap. Ecstatic to find out that his daughter has been revived again, Carmody decides to retire and spend his days living in a cabin near the Blue Ridge Mountains. However, this retirement would not last long as a Skrull working for the United States government named Velmax would offer Carmody to join a newly-reformed First Line team as a covert unit. Carmody Institute, owned by Eternal Brain, served as the team's headquarters. Carmody then upgraded his robotic body into a more adaptable homunculus form and became an active member, gaining mobility through implantation into a sentient robot called Walkabout. Eternal Brain would become an active member of the First Line for many years to come, using his brains and intelligence to aid the team in their many missions to come.

## Powers and Abilities

### Powers

The Eternal Brain can project his thoughts, speech and hearing over distances of hundreds of miles, even reading and altering the thoughts of others. In person, he speaks and hears using sound equipment and perceives his surroundings through similar technology. He could see without artificial aid after transferring his consciousness into a series of miniature bodies, but his powers are otherwise unaffected.

### Abilities

A brilliant scientist, the Eternal Brain is an expert in genetics and robotics. He created two human bodies to live inside, the first growing to old age, the other did not grow beyond an embryonic state. He also constructed a number of devices to house his brain form, including mechanical bodies that replaced the need for a physical one. He has access to a rocket ship and other devices of his own design.
