Connor was a child born from two vampires: seemingly an impossible event. Unable to physically give birth, Darla committed suicide in order for Connor to be born, leaving Angel to bring up his son alone. Baby Connor became a part of the Angel Investigations family, until Wesley was tricked into believing that Angel would kill his son. After Wesley kidnapped Connor, Angel’s arch nemesis Holtz stole the baby and jumped into a hell dimension.

Connor was raised by Holtz in a terrible dimension called Quor’toth, where time passed differently. Holtz named him Stephen and told him lies about his real father, Angel. Connor grew into an exceptionally strong teenager and learned to despise Angel. Not much is known about Connor’s life in the hell dimension, other than the fact that he had to constantly fight for his life.

Only weeks had passed back in Los Angeles when Connor managed to escape Quor’toth - now a teenager and hell bent on destroying Angel. In order to finally defeat his nemesis, Holtz staged his own death, making Angel look guilty - whilst at the same time making Connor hate Angel even more. Enraged, Connor sealed Angel in a box and sunk him to the bottom of the ocean.

In the meantime, a seemingly innocent Connor lived in the Hyperion hotel with Fred and Gunn. Upon Angel’s return, relations were still shaky, yet slowly improved. Due to his difficult upbringing, Connor found it hard to develop emotional attachments to people, but he formed a close bond with Cordelia. When a demon known as The Beast rose from the ground in the very same place that he had been born, Connor felt responsible and as fire reigned from the sky, Cordelia allowed him to seek comfort in her. Their night of passion brought forth another strange pregnancy - the arrival of Jasmine, a Goddess from another dimension who seemingly brought joy and hope to all she encountered. Whilst trying to love Jasmine, Connor dicovered that he only felt more isolated than before, and mourned Cordelia, who was in a comatose state. He decided to hurt not only himself but to take others with him. In a final act of love, Angel agreed to take over Wolfram & Hart in exchange for Connor having a completely new life with no memories of his time with Angel.

Unknowing of Angel’s relationship with their son, Connor’s new parents came to Angel for help because of his emerging powers. The demon Cyvus Vail forced Angel to let Connor fight one of his enemies: Sahjahn. Connor agreed to the fight, but was outmatched. Meanwhile, Wesley discovered Angel’s deception and encountered him at Vail’s. No longer trusting Angel, he returned Connor’s memories which enabled him to kill Sahjahn. Connor returned to his family and seemingly out of Angel’s life. Before his final battle with the Circle of the Black Thorn, Angel visited Connor for coffee, where Connor revealed that he knew Angel was his father and was grateful for all he had done for him. Connor also showed up to fight Hamilton by his father’s side. As the Senior Partners begin to exact their vengeance, Angel told him to go home and that as long as Connor was alright the Partners could never destroy him.
