Lincoln Clay is a Vietnam War veteran who starts his own criminal empire while seeking revenge after the Marcano Crime Family killed his adopted family, the Black Mob, and left him for dead.
- "Family isn't who you're born with, it's who you die for."
- — Lincoln Clay
Lincoln is a man who is loyal to those who he regards as his family. He is grateful towards Sammy and his family for taking him in, seeing Sammy as a father-figure. He also saw Father James in a similar light. He would give up his personal goals and ambitions without any hesitation in order to help his adopted family out. Despite his loving relationship with his foster family, Lincoln struggled to find an identity for himself and to find a place where he could belong, possibly the reason he served in Vietnam. However, what greeted him was carnage, depravity, and unspeakable violence. Lincoln's war experiences scarred him mentally and physically, leaving him unable to sleep soundly and insisting on sleeping in the basement, most likely suffering from PTSD. To the outside world, however, Lincoln is usually quite personable and outgoing, willing to make friends with people of different ethnicities and look beyond the racial tensions of the time. As a criminal, he is cool, cunning and calculating with an eye for the big picture, easily working out a methodical way to reach his goals.
Throughout his war with the Marcano family and other rival gangs in the multiverse, Lincoln displayed a much darker side to his personality. The betrayal he suffered from the mob makes Lincoln much more cruel and bloodthirsty towards his enemies, openly displaying the bodies of victims to the public to scare all who opposed him.
