- "Open your eyes, son. Look at the world we live in today. We are witnessing the birth of a new race of superhumans. Beings who can fly, tear through buildings, and outrun race cars. They will make what you can do, obsolete. In that world, throwing a football is a joke!"
- —Silas Stone to Victor Stone[src]
Death of his wife
At some unknown point in time, Silas's wife died, leaving him the sole caretaker of their son, Victor. Finding it difficult to bond with him because of his grief he threw himself into his work, even putting it before Victor.
Silas and his team were brought a Mother Box and a creature by The Flash, who had subdued the creature as it attempted to plant the device in Central City. Days later after working around the clock, and learning virtually nothing about the device or the creature, Silas received a call from The Flash who inquired on their progress. After their conversation, Silas received a notification on his phone reminding him of his son's football game, which he decided to disregard. Later while analyzing the device, Silas was made aware of Victor's presence in the lab, with an argument between the two ensuing. After Silas made it clear that he wouldn't be coming to any of Victor's football games, he was notified by Sarah that something was happening with the device, prompting him to tell Victor that they would continue their discussion later. As the Mother Box activated, Victor in a fit of rage grabbed a hold of it, despite Silas's protests not to. After a wormhole opened from the Mother Box, severely injuring Victor, Silas made the call to get Victor into the red room. He, along with Thomas Morrow and Sarah Charles made their way there, while avoiding several of the creatures that had come from the wormhole that were in pursuit of them. Using the technology in the room, Silas made an attempt to have Promethean skin graphs graphed to Victor to repair his damaged tissue, though while doing so, the machine melded to him instead, turning him into a cyborg. After Victor awoke, Silas tried to reassure him. He soon after received a phone call from The Flash, with several Parademons bursting into the room at the same time. Silas then attempted to fight them off with a fire extinguisher, though to no avail. However, he and his team were saved by Victor due to his new found abilities, and the Flash. Afterwards, Silas was reprimanded by Victor for making him into one of Silas' "projects". Silas later attended the ceremony honoring the Justice League at the Capitol Hill, displaying great pride in his son.
