Ulysses S. Grant

Origins
Ulysses S. Grant was born in Point Pleasure Ohio, a port known for its prostitution services. Fearing the worst, Grant ran away at a very young age, where he was taken in by the Booth family in West Point, and became friends with their son, John Wilkes Booth. This was also where they met a young Abraham Lincoln, and the three became best friends. They trained in all sorts of combat together, and they were said to be the only ones strong enough to fight each other. He built up a strong shooting rivalry with Booth, and practiced his knife fighting skills against Lincoln. They lived together most of their lives until the Civil War, where Ulysses and Abraham went off to fight at the front lines, while Booth stayed back as a sniper to defend West Point.

Civil War
Ulysses S. Grant was the best soldier in the Civil War, with Lincoln being the only one anywhere close to rivaling him. Being trained in every form of combat, he was an extremely efficient soldier, but was frequently injured due to the sheer number of fights he was in. While Lincoln was likely a larger danger on the battlefield, Ulysses S. Grant fought in every single battle in the war, making him much more successful but putting him in harms way several times. By the end of the war he had sustained severe brain damage. He recovered from the crippling organ damage under the care of Booth for the 4 years Andrew Johnson was in power, but eventually Booth had to flee to avoid persecution for "killing" Lincoln. However, when officials found the celebrated war hero, they exposed him to the public, and through circumstance, he was elected president.

Presidency
Despite his former intelligence and glory, after the war Grant was only a shadow of the man he once was, and was unable to perform presidential duties effectively. He was still able to run for two terms due to the relative peace at the time, but was too mentally damaged, and was only hurt farther by the stress of his duties.

Post Presidency
After being president, Grant moved back to his and Booth's mountain home, where he was able to recover after a few months. However, after hearing about Lincoln going into deep hiding, the two moved to him and lived with him until the Moon Wars, where they fought alongside him.
