No idea..he genually seemed like a good guy..and i thought I remembered Adrian getting attacked at some point..and is vigilante a bad guy..? Or is he just going after Oliver cuz he believes he failed this city? Prometheus knows Oliver is the green arrow..so why work so hard to keep him in office? Why cover up the the fact the arrow killed that cop? It makes sense he knew exactly what happened if he was Prometheus..but why go through all that trouble to make the arrow look bad only to help cover it up..? At this point i don't understand his motive..

Maybe Claiborne's son

LoL I had the same theory on IMDb months ago, i.e that Adrian Chase (which per comics is Vigilante) is infact the "Red herring" thus making Chase on Arrow, Prometheus, Vigilante will be a nobody but they threw him in there to confuse us. Its also very likely that Claireborn's son is Chase but he had a mental breakdown, was sent to an asylum from which he escaped, killed "Adrian Chase" and took his place and then played a "long game" just so that he can take his revenge on the Green Arrow

Prometheus then who the hell is Vigilante? I'm pretty sure they're pulling a Zoom and Vigilante is the Real Adrian Chase and Prometheus stole the identity, or just someone else. Any other ideas?

Maybe Chase/Prometheus has multiple personality disorder and was actually fighting with himself up in that roof? lol

Well this sucks. A new character that I actually liked turns out to be the bad guy, go figure.

I'd be surprised if its anyone other than him.

As funny as it might sound I kind of agree with Xcalat3 about the multiple personality disorder. Prometheus and The Vigilante are both Adrian Chase. The fight on the roof was all in his head. How else can you explain his surviving being thrown off the roof.

hmmm good point

I'm in the minority(?) of folks who disliked Fight Club, but, yes, I admit this theory has merit. I just hate the idea of not eventually folding Vigilante into the group. If he's both Vigilante and Prometheus well that's impossible.

LOL Unlikely, remember Chase took the visor fragment of Dinah which made her suspect that Chase was vigilante but Chase knew who Vigilante was so he called him for a meeting and tried to pis him off because he knew if he pissed him off enough, he would try to kill Oliver so obviously when Vigilante was getting ready to sniper Oliver Queen, Chase was standing to his left so he cannot be at 2 places at once, Chase knew that Dinah had taken the Visor fragment off the desk moments earlier, he set up Vigilante cause he knew the GA Team will catch him putting Chase in the clear. Chase is good at anticipating outcomes, he does play a gamble there because there was good chance the GA team would not have gotten in time and Vigilante would have killed Oliver

DC did introduce a brother of Adrian Chase and he had a Vigilante title for a time. But I think screwing around with canon is just a cheap trick and not innovative at all.

yeah kind of sucks they made him the bad guy

Prometheus must be someone related to Vigilante. Prometheus breaks Oliver to confess so he can justify murders carried out by himself and Vigilante. Now that oliver accepted his true self, he can't judge vigilante.

I think Vigilante was someone Chase hired just like that other chick so that he can piss Arrow off, enough to make him kill but he could not and Vigilante was well out of control by that time and he wanted vengeance on Arrow, I personally think either Chase or Vigilante is Kovar's son.
