New 52 Deathstroke

Deathstroke's altered origin is introduced in Deathstroke #0. The fact that he participated in the military at 16 and met Adeline has not changed. Already a legend in the army, Slade was drafted into Team 7 and went on many missions. In one mission, Slade was gravely injured and had to go under an operation that enhanced his abilities, making him virtually a super-human. After this, he married Adeline and had two sons, Grant and Joseph. Around this time, Slade received intel that informed his best friend, Wintergreen was caught in Somalia. He donned a mask and flew to Somalia to rescue Wintergreen, slaughtering all the captors. Deathstroke the Terminator was born. As his fame grew, his enemies did too. An attack targeting his house seemingly killed Joseph and Adeline. With evidence that the attack was from North Korea, Slade vengefully killed a pack of North Korean soldiers, but lost his right eye in the process. It is later shown that Joseph and Adeline are still alive.

This origin was again changed in Teen Titans: Deathstroke #1. After a mission that involved detonating a children's hospital which Slade was unaware of, he quit the army. After Team 7's termination, Slade started to operate under the Deathstroke identity. He took Grant on his mission, considering him as not only his son, but as a business partner, and the only person he could trust. But during in a mission in North Korea, their refuge was infiltrated and North Korean soldiers barged in, firing into the house. Grant was shot, and as Slade looked backwards at his son, a bullet penetrated through his right eye, blinding it. Enraged, Slade went on a massacre and slew the soldiers. However, Grant was presumed dead. Now, Slade works for the sake of his daughter Rose, as he knows the only thing that will keep Rose safe after he's gone, is money. It is unclear if Rose's mother is Adeline or not.
