This section of the history takes place during Flashpoint, a massive crossover event set in an alternate timeline to the mainstream DCU. History was completely changed when Professor Zoom finally found a way to erase his nemesis the Flash without harming his own legacy.

In an effort to save his mother's life from the Reverse-Flash, Barry Allen unknowingly changes reality, creating a new world in which his friends' lives, Superman included, are drastically different.

Lieutenant Neil Sinclair was a soldier selected by General Sam Lane to be the first subject in a secret government project he was starting. Lane's objective was to create a super soldier for the American government that could combat super powered enemies during for war. Sinclair was enthusiastic and, over time, was forced to stay in an underground government base to be tested on. Soon, "Subject Zero" as he came to be called became cold in nature, developing new powers that he hid from his higher-ups.

After finally being approved for field operation, Subject Zero went insane and accidentally killed all of his ally soldiers before actually eliminating his intended target. For this, he was deemed a failure and held in super powered captivity while Sam Lane shifted his attention to the next subject in their "Project Superman" - an alien that crashed in Metropolis that they named "Subject One".[1]

Subject Zero used his hidden ability of telepathy to communicate with Kal-El for many years as the two grew up in captivity. When Kal was a boy, he broke Subject Zero out of his cell. However, instead of escaping, Subject Zero targeted Sam Lane's daughter Lois Lane, blaming General Lane for betraying him for Kal. Kal stood up to Zero, though, developing an attraction to Lois instantaneously. In an effort to save his daughter from the monster, General Lane blasted Subject Zero and himself into the Phantom Zone where the two, together, lived in sentient paralysis for years.[2]

Subject Zero and Lane were freed from the Phantom Zone when a group of heroes came to rescue Kal, unintentionally cutting the power source to the Phantom Zone holding device. Free, Sinclair immediately finished what he started by killing Lane. Then, he hunted down Kal and Lois Lane, wanting to continue his revenge against General Lane. In their fight, despite being the better skilled and higher-powered combatant, Subject Zero was killed when Kal punched him through the abdomen in a fit of resistance.[3]
