Slade was Trigon's so to be called right-hand. He was really close to Trigon until he knows all of his secrets and when the moment he knew that Trigon has a daughter, who shares the same birthday as him. He has the same ancient symbols on body issues as well. When he met the a man filled with ancient knowledge to inquire about the issue.
He was shocked to know that it was a traits from his family , who are surprisingly related to Trigon, so he was Trigon's nephew and by birth he and Raven were betrothed. He was already in love with her but knowing the news that she already has a partner made him extremely mad . He ask his friend, who was Starfire's older sister, called Blackfire to go to earth and tell them that Slade is coming for her. As usual , she did what she was told to do. That very morning, Damian was sitting at the edge of the bed while Raven was still asleep. He was concerned when he saw the symbols were increasing day by day. He called Dick and Starfire to tell him what was wrong . Starfire told him that Raven was unknowingly engaged as a kid due to blood trait relationship. He was devastated but she told him that it wasn't Raven's fault that she is still clueless about this and she is afraid of what is happening to her. They heard the door bell rang and Starfire went to get the door. She was indeed surprised to see her sister , Blackfire came here to visit. She gave her sister a big hug and was asked if she had a new member in the troop. Starfire knew that this wasn't going to end well. She introduced her to Dick , Damian and Garfield , who were playing video games , in the living room. Starfire told that this were the only member of the troop.
The white lie didn't even last for a second , when they heard Raven screaming, Damian rushed to her room and she told him to stay right there. She doesn't know what's happening to her. Blackfire came in calmly and told them that Slade is already beginning his hunt in search for Raven. Starfire was terrified "S..SL...SLADE!" "Who is Slade?" Dick asked. Starfire told them that Slade was Trigon's late nephew and was the one who was supposed to merge powers with Raven through a term called marriage , so he could take Trigon's place and conquer the universe. He will be the most powerful being in the whole universe.
"He will have to go through me, if he wants my girl!" Damian shouted. Blackfire was surprised. "Wait until Slade hears about this , an mortal boy wants to go against the immortal warrior, Slade!" She said with delight. She flew back to the airship she used. Raven was afraid "Will you always be with me?". Damian kissed her passionately and told her "I will always be with you as long as I am alive!"
