From An al Ghul To A Fenton Now A Wayne (DPXDC)

Danny wasn't a Fenton and neither was Jazz and Elle either. Born as Daniel and Jasmine al Ghul. The full siblings of Damien al Ghul, sharing the same father. Jasmine had come back alive from her first mission but had refused to eliminate the target at the age of 5, Ra's saw this a disrespectful act and cowardice had killed her, Talia had felt such remorse that after her father had left she swept up her child and revived her in the Lazarus Pit. Then had brought her to a small town in Illinois called Amity Park and left her at the doorstep of Maddie and Jack Fenton where she would hopefully never be found by the League. Damien and Danny are twins and they had been sent on their first mission at the age of 5 as well, but weird Damian had succeeded Danny had failed, he had died on his mission, and had not even been able to kill his target first, Ra's took as a sign that he was not worthy to be brought back from the dead and had ordered Talia to dispose of the boy's corpse. She, however, could not and had brought him back in secret as well, bringing him to the same town as his sister but instead of leaving him at the Fenton household left him at an orphanage and made him promise to never tell anyone about his past. She had hoped even if they didn't grow up as siblings, that they would be friends but as fate would have it, the Fentons' decided to adopt another child and the child adopted was the biological brother of their adoptive daughter. Shortly after, Danny had defeated the former ghost king, He had been kidnapped, tortured and experimented on by the GIW, all before he was officially the new Ghost King. Jazz, out of desperation turned to their parents to help save Danny, telling them the truth. Together with the help of his friends, they had rescued him but then there was an accident in the lab when the GIW came to take him back and it killed both Maddie and Jack and had turned Jazz into a halfa as well.
