Conklin

Conklin is a mercenary for Baron Reiter's cultivation operation.

Cultivation operation on Lian Yu
After Oliver Queen stopped a Slam worker from running away, Conklin asked if Oliver was going to ask him to surrender, before knocking the worker out. When Oliver asked what the product was, he told him it was a hybrid of heroine and cocaine. Shortly after, a mercenary reported of a whole cake of Slam missing, in which Conklin deduced the runner was a distraction. Conklin told the other mercenaries to round up the workers so they could learn who stole the slam. Conklin told the workers to come clean. As none of them did, Conklin executed a worker. Before he could execute another, he was stopped by Oliver, who told him he has a way to extract information from people. After a woman came clean to stop Oliver from torturing a worker, Conklin pointed a guna t her. Conklin was told by Oliver that Baron Reiter won't be pleased if he learned he had been exterminating his work force. Conklin was told by Oliver that he could take her somewhere on the island where she can't be found. Conklin agreed but sent a mercenary to follow.

When Oliver returned and reported the mercenary had died from a landmine, Conklin became skeptical on Oliver. He asked why none of the mercenaries had died until Oliver showed up. Conklin then asked Oliver to bring him to the woman's body. On the way, Conklin noted that Oliver didn't sound like a man who committed murder for the first time. When they arrived at the cave, Conklin checked the woman's pulse and found none. Conklin told Oliver to get rid of her body as the cave could be useful. Conklin later wandered off and found Oliver's kit supplied by A.R.G.U.S..

Conklin approached Oliver, revealing he was aware Oliver is undercover. Conklin then took Oliver to Reiter. When he tried to report Oliver, Reiter told them there were bigger issues as Reiter had found John Constantine snooping around. When Reiter told Oliver to follow Constantine and obtain what Constantine was looking for, Conklin told Reiter Oliver couldn't be trusted. Soon after, Constantine broke free of his cuffs and Conklin was knocked out by the former.

Conklin voiced his concerns to Reiter for trusting Oliver, although he is a mole. After Oliver departs when he and Conklin deliver food to the Slam workers, Conklin conspires with a Slam worker named Vlad to kill Oliver. Vlad attacked Oliver and tried to drown him, but Oliver started to run to the shore. Oliver then broke Vlad's neck, killing him. Conklin witnessed the whole fight with the Slam workers, proclaiming that he better have a heck of a story to go along with Vlad's body.

Conklin and Oliver brought their stories to Reiter with Oliver arguing that Conklin set Vlad up to kill him as he had it out for him from Day One. Using a "spell", Reiter determined that Conklin was lying and had his men take Conklin away. Oliver was then ordered to whip Conklin for his betrayal, despite the latter pleading and apologizing.

Conklin discovered Oliver and Taiana on the Lian Yu shore after Oliver was injured by a shark while swimming back from retrieving papers from the sunken Amazo ship. Conklin was shocked that Taina was very much alive and remarked that not only was Oliver a spy, he was also a liar and he was going to have fun tearing Oliver apart.

Personality
Despite his sadistic nature, Conklin is quite loyal to Baron Reiter, although his loyalty causes him to behave out of order and make him look like the traitor. This would happen when he convinced a prisoner to kill Oliver and try to frame Oliver when Baron refused to believe he was a mole. This would cause him to be punished severely.
