RoyOllie

Roliver is the slash ship between Oliver and Roy from the Arrow fandom.

Canon
Oliver first hears about Roy when Thea tries to get Roy a job at Verdant, in an effort to steer Roy away from a life of crime, but Roy never shows. His life is changed by Oliver when Roy is captured by a man seeking to avenge the murder of his wife by live streaming his execution of people from The Glades. In the broadcast, Roy says his life isn't worth much, but Oliver comes to his aide and saves Roy's life at the last minute. This proves to be a life-altering experience for Roy, who wants to do something with his life and possibly finally starts to believe that he is worthy of happiness.

Roy goes to great (sometimes illegal) lengths to find "The Hood" and Thea helps him, which leads them to Merlyn Group where they bump into Oliver. This is the official meeting between Roy and Oliver, and when they admit to Oliver why they're there, Oliver tells Roy to stop looking for "The Hood" as he'll put Thea in danger. Roy doesn't listen and when Moira broadcasts The Undertaking, Roy stays in The Glades to help people because it's what "The Hood" would do.

INTEL AGENT

5 months after the catastrophe in The Glades, Oliver returns to Starling City and runs into Roy at Verdant when he seeks out Thea, saying "still here?" to Roy who replies "always". Roy still tries to stop crime at night despite promising Thea not to, and has been doing so since "The Hood" disappeared. Oliver realises that Roy has the finger on the pulse on what goes on in The Glades and finally meets Roy as Arrow. Roy is stunned by meeting his hero and The Arrow asks what he wants. Roy kind of stumbles, saying he hadn't thought of it past meeting him, but reasserts his intent to save the city, inspired by The Arrow. Oliver gives Roy the task of bringing him intel in exchange for stopping his nightly crusades and Roy agrees.

After Oliver's rescued by a mysterious vigilante, he asks Roy to track her down and Roy does. Although Oliver takes the (self-titled) "disapproving big brother" tack with Thea, he recognises Roy's worth. Roy continues to be heroic, although he doesn't seek out criminals, such as when he saves Sin's life when she's shot at the Cash For Guns initiative. When Sin approaches Roy about her missing friend, Max, he and Thea try to help Sin find Max, who eventually turns up dead. Roy takes a picture of the body and shows it to The Arrow, who tells Roy to stay away. Roy protests that just providing intel isn't enough for him anymore, when he suspects The Arrow knows something he's not letting Roy in on. In an effort to continually keep Roy away from trouble, Oliver shoots an arrow through Roy's right knee.

MIRAKURU

Thea takes care of Roy in her room, and hides it from Moira who thinks something's wrong with Thea and enlists Oliver to decode. This brings about a hilarious scenario where the group have to tell Oliver that the "crazy vigilante" shot Roy. Oliver is completely unapologetic, pulls the arrow out of Roy and enlists Diggle to patch Roy up. Before he leaves Oliver tries to impart his message — that he wanted Roy to stay out of trouble. The trio of Roy, Thea and Sin don't adhere, however, and ask Laurel for legal help with Max's files. Roy decides to break in and find Max's psych evaluation, but is caught by Cyrus Gold. He is injected with Mirakuru and Oliver revives Roy, telling him he won't lose someone else. Roy awakes and Oliver brings him back to the mansion where Roy's knee has healed completely.

5 weeks later Roy realises that he has super-strength, which freaks him out and he hides it from Thea, until the bomb threat at the Unity Rally where he saves her and Moira by catching and holding a power mast. Thea tells Oliver what happened and Oliver thanks Roy for saving their lives, realising that Roy's powers have begun showing and telling his team they will need to keep a close eye on Roy lest the powers start affecting his mind. Roy decides to test his powers with Sin and the serum affects his mind as he nearly kills a man until Sin stops him. Roy refuses to let Thea and Sin help him and cries alone in despair. Thea tells Oliver that Roy's changing and Oliver seeks him out as The Arrow, asking Roy to let him help train Roy to control what's happening to him, to which Roy agrees.

Fanon
