He served as the main antagonist in the Season Six episode "Arrow".
He was portrayed by David McIlwraith.
While attending a fundraiser, a masked vigilante named the Green Arrow Bandit stole a rare diamond necklace off of Martha Kent's neck that Lionel loaned to her. Lois Lane tried to stop him but he escaped and vowed to find the man behind the costume.
At Oliver's Queen Tower, Milo questioned her about the robbery and the Green Arrow but she gave very little details. To his annoyance Lois had tarnished Milo's business in the article she wrote for the Planet.
Later Milo had two of his men abduct Lois from her apartment at the Talon and took her to an abandoned foundry.
Lois' attackers tried to torture her into revealing Green Arrow's identity by submerging her into a tank of water. She thought Green Arrow was responsible for her kidnapping, but Milo appears.
He tells her that she has humiliated him by reporting the thefts, and Green Arrow has ruined his business by stealing from his clients. Lois said that she didn't know who Green Arrow was but Milo didn't believe her and almost drowned her.
Milo instructs them to kill her, but just as they shoot, the bullet is deflected by an arrow. Green Arrow arrived and incapacitates the thugs and Milo. He is presumably arrested.
