Otis Graves

"You think you stopped us tonight, but the fuse was lit. And it's gonna be beautiful."

- Otis Graves to Supergirl

Otis Graves was a former Cadmus agent, a member of the Children of Liberty and the brother of the late Mercy Graves. After Lex Luthor's arrest, Mercy went to work for his mother, Lillian, at Cadmus and Otis joined with her. After Lillian's arrest and Cadmus's downfall, Mercy and Otis eventually found Agent Liberty and joined the Children of Liberty. Mercy and Otis were both later killed by an alien while attempting to kill Supergirl.

Early life
In 1996, Otis and his family went on vacation to an unknown destination and he was somehow dangerously injured by his sister. So injured in fact, that paramedics had to be called to resuscitate him.

Project Cadmus
After Lex Luthor's arrest, Otis and Mercy teamed up again and the two joined Project Cadmus, run by Lex's mother, Lillian. However, Lillian was later arrested by Supergirl and Cadmus was shut down.

Working with Agent Liberty
When Ben Lockwood was handing out papers to citizens in National City, Otis came across him and applauded him for his views on aliens. Later, Otis and Mercy pulled up next to Ben in a limo in the street. After explaining their plan to track down and murder Fiona Byrne, Mercy introduced herself as well as Otis. The three returned to a hideout where Ben was given a suit to don when working with them. Under the orders of Liberty, the two ambushed Dr. Rohan Vose outside his lab and proceeded to use lasers to slice off his spikes that stuck out of his arms in order to gain access to the lab. After Otis took one he took the other for playful reasons and Mercy criticised him for not acting professional. Just as the entrance to the lab opened, Supergirl smashed through a window but was deafened by a device used by Otis and had her legs handcuffed together by Mercy. Otis then shot her through a window at the end of the corridor and the two entered the lab. However, Supergirl managed to escape from the cuffs as Mercy found the package they were looking for. As the two prepared to leave, Supergirl flew back in but stayed behind in order to protect Dr. Vose from a bomb thrown down by Otis as the brother and sister made their escape. The two travelled back to Agent Liberty's lair and when Otis began playing with nunchucks, one of them hit something and Mercy threatened him not to do it again. When Liberty entered, Mercy told him their mission was successful but when Otis told him that Supergirl showed up she kicked him. Liberty then asked for the EMP and when shown it, he told then siblings to prepare for war.

Later, at President Marsdin's gathering for aliens, Mercy and Otis were instructed to attack it and after stealing uniforms from two D.E.O. agents, they threw the EMP which turned off all the lights in which the gathering was being hosted. After Mercy failed to kill Alex Danvers. the siblings attempted to flee on motorcycles but were followed by Supergirl. Knowing she couldn't lose her, Mercy resorted to shooting Otis in the shoulder which caused him to fly of his vehicle and was sent plummeting down, forcing Supergirl to stop and rescue him. As she did so, Mercy managed to escape. When incarcerated at the D.E.O., Otis refused to answer any questions that agents asked him.

Director Alex Danvers attempted to question Otis on Mercy's whereabouts but he only teased her, explaining that she could be at an Italian restaurant they both liked. However, Alex managed to frustrate Otis by saying Mercy was his boss and she was in charge, causing him to get up and try to attack her but she managed to floor him and asked Agent Jensen to take him back to his cell. After failing to kill Lena Luthor and Supergirl, Mercy was also sent to the D.E.O. in a cell next to Otis. The two managed to escape however, manipulating Agent Jensen into turning on the D.E.O.. The three travel to Agent Liberty's lair and use a device to send Kryptonite into the atmosphere, harming Supergirl.
