Malcolm Merlyn

Malcolm Merlyn is the CEO of Merlyn Global Group. He is the husband of the late Rebecca Merlyn and father of Tommy Merlyn and Thea Queen.

Prior to the Series
At some point Malcolm married Rebecca. The two married and got a son, Tommy, in February 1991. He has encountered and befriended Robert and Moira Queen before that, as they have known Tommy since his birth. In return, he has known Oliver since he was born.

In 1998, Rebecca died and Malcolm got depressed. As he traveled abroad to fill the voice, he abandoned his son who got even closer to the Queens during his absence. Sometime in 1999 he has returned and begun an affair with Moira and fathered Thea, who was born in September 2000.

Some time after Robert's death either Malcom or Moira disclosed that Thea is Malcom's child. He has since tried to become closer to her but does not seem to be fruitful so far.

in the middle of the night, in my dreams
In Early 2018, Malcolm discussed Roy Harper's future plans with him. He does not seem to approve of Thea's relationship to him, since he pointed out that Roy comes from a working class family and does not believe he is capable of doing better.

worked too damn hard for this
When Oliver was back in Starling City during late May 2018, Malcolm has trespassed into the Queen's house.

Malcolm visited Lian Yu twice while Oliver, Felicity, Dig and Lyla were staying there. The second time he came around, he brought Damien Darhk along, indicating that they were friends.

Trivia

 * Nobody really likes him, but they're stuck with him.
