McKenna Hall

Detective McKenna Hall is a former police detective of the Star City Police Department. She is an old friend/the ex-girlfriend of Oliver Queen, an old friend of the late Tommy Merlyn, a good friend of the late Laurel Lance and the sister of an unnamed woman. When Oliver needed help to track down the maker of Vertigo, he went to her for the police's file on the Count. Shortly after, McKenna and Oliver started dating and began a romantic relationship. At the same time, McKenna was chosen by Quentin Lance to be his partner in uncovering the Hood's identity. However, her police career was halted when she was shot by Helena Bertinelli and became temporarily paralyzed. Due to this, McKenna had to move with her sister to Coast City, which she claimed has the best physical therapy facility in the country. Her relationship with Oliver subsequently came to an end, though they presumably remain on good terms.

Early life
McKenna was a close friend and fellow partygoer of Oliver Queen and Tommy Merlyn. She once got herself and Oliver banned from the club Deville for taking off her clothes; she claimed there were no signs around which stated she couldn't do so.

While Oliver was supposedly dead for five years, McKenna became a police detective with the SCPD. Through her job, she became acquainted with Laurel Lance.

Relationship with Oliver
Oliver encounters McKenna at the SCPD. Happy to see each other again, Oliver notes his amazement that she has become a cop. He talks to her trying to find info about the Count. McKenna gives him what little information the police have on him. Later when Oliver is doing a deal with the Count, McKenna along with Quentin Lance disrupt the deal with the Count escaping. At the Queen Mansion, Quentin and McKenna confront Oliver about the incident with her revealing that she spotted Oliver at the scene. When the Hood nearly overdoses the Count, Quentin and McKenna arrive with Quentin telling him that his actions prove that he is what he always thought he was; a murderer. McKenna contacts Oliver the next day and tells him the news saying it was good seeing him again.

Oliver flirts with McKenna to implant a chip on her phone to eavesdrop on her conversations about the Dodger and also at the same time asked her out. They went on a date which was going well until McKenna unintentionally mentions his life on the island. McKenna then got a call regarding the dodger and had to leave the date as awkward as it is. Although the new spark of the romance still ended well for them in the end.

Oliver and McKenna continue their possible relationship and even talk about fitting it in both of their busy lives. When McKenna says she is willing to do it, Oliver was delightful.

Reluctantly breaking up with Oliver and moving to Coast City
As Oliver's club Verdant is opening, Oliver asks McKenna to be his date for the night. McKenna and Quentin arrest the Huntress as she fell for the trap they set which was sending two empty vans, making Oliver and Helena believing one of them carried Frank Bertinelli. McKenna and Quentin ask Helena who the Hood is, she tells them it's Oliver but the two don't believe her. During Helena's pursuit for her father, McKenna calls for backup and approaches Oliver and McKenna. McKenna tells both the Hood and Helena to hold their ground and surrender, but Helena fires her shotgun at her. Though McKenna was wearing a vest, she was still harmed by a bullet, as she became temporarily paralyzed. She tells Oliver she is leaving the city, though Oliver says he will follow her, but McKenna tells him to stay.

Personality
McKenna is a very honest person and is very passionate about her work as a police detective. She is similar to Quentin Lance at first, believing in law and order; therefore, McKenna is against the actions of Oliver Queen (under the persona of the Hood) despite all the good he has done for Starling City.
