Most of the Immortal's origin is unknown, even to him. Sometime in his past, an accident happened to him that gave him his immortality and superhuman abilities. He would take up the duties of a knight, an explorer, fight in the American Revolution, become President of the United States, taking the alias of Abraham Lincoln, fight in the World War II, and become a superhero. Sometime after becoming a superhero, he would meet Cecil Stedman and become one of the original members of the Guardians of the Globe.[2].
Original Guardians
The Immortal had found Bi-Plane attempted to commit suicide to infect the Denver population. Immortal grabbed him and threw him into space, killing him. He got an urgent call from the Guardians base and headed to Utah. He stated the secret code and the confused Guardians looked at him as he had called them. The Guardians are killed by Nolan Grayson and Immortal witnesses him and says "I never liked you". He is decapicated and Omni-Man replies that the feeling is mutual. The Immortal is buried along with the other Guardians. Some young men attempt to dug up his body, believing that drinking his blood will make them immortal as well. The Mauler twins stop them, taking his head to a lab. They revive him while attempting to enslave him. The beacon fails and Immortal flies out. He finds Nolan on a beach and attacks him, demanding to know why he killed the original Guardians. Nolan impales him and rips his torso in half. He would again be revived by doctors in the white room at the Pentagon. He would rejoin the Guardians of the Globe and have many adventures with them.
Reboot
The Immortal says "I never liked you" and Omni-Man replies "The feeling is MUTUAL" while seemingly killing him.
Years later, Mark touched a white light that put him back into his body at the time before he received his powers and with all of his memories. He attempted to talk to his father about not killing the Guardians of the Globe again.[3] Nolan became angry and immediately attacked Mark. Mark led him to Utah where he tricked Nolan into smashing into the Guardians of the Globe headquarters where The Immortal and several others were located. Mark revealed Nolan's plans to the Guardians and they teamed up and subdued Nolan. During the battle, The Immortal had his heart punched out of him by Nolan. Cecil Stedmen soon arrived and agreed to bring Nolan back to the Pentagon and restrain him. The Immortal was revealed to have survived the attack. [4]
