White Canary is their replacement for Black Canary , and in universe makes more sense . She trained with Nysaa for 3 years , spent 7 more in the League , is a vigilante on her own . Yes but why though ? And if I ' m being honest , you can ' t have Laurel who at this point in show history would have been training for two and a half years yet you can have Mick who has . A flame gun ? Mick doesn ' t even his Chronos training as we ' ve seen given his fight with the ninjas and again , Steel has no type of training at all but has had powers for a week or two . White Canary makes sense to be a part of it but so does black canary if we ' re judging by apparently skill . Vibe has been around for 1 . 4 seasons , Its just now he has actual battle powersYeah but again there ' s that whole issue of him not really knowing what to do with them . I recognize he ' s been there since season 1 but his powers are fairly recent as is him knowing what to do with them . The hawks probably fucked eachother to death . Huntress is in jail . IDK about Lyla but her husband is in jail escapee mode . So ARGUS probably cant help . But I bet a presidential pardon is gonna be when shes back on arrow . Again , the Hawks have lived over 200 lives so really , the show could have had Hawks that were part of the JSA and had them come along as revamped characters when they picked up Amaya . Diggle was also in jail , granted wrongly accused but this is where that whole all hands on deck thing comes in . Argus doesn ' t technically exist and I don ' t think anyone is petty enough to care about one escapee when the fate of the world is at stake . All of argus doesn ' t have to help anyways , just Lyla preferably . Harper Arsenal is Speedy and the Red Arrow combined into one person . Thea is Speedy given a gender change and new back story . Wildcat just disappeared . Roy is just meant to be Arsenal while Thea Queen is not a gender flipped speedy since Mia Dearden , who she ' s based on , was known asspeedy . And even at that , what does that have to do with either of them not appearing in the crossoverpossibly JSA creation since they ' ve been arrow verse characters since the start . Meanwhile , Wildcat is still alive and apparently still in Star City according to Guggenheim . Logically the Justice League of CW should be Oliver Queen , Barry Allen , Sara Lance , J ' onn Jonzz , Kara Danvers , Ray Palmer , FirestormJaxStein , Daniel Jackson . err . Citizen Steel I mean , and VibeI wouldn ' t have minded Oliver , Black and White Canary , Diggle , Arsenal , Speedy , Barry , Firestorm , Ray , Kara and J ' onn , Clark and Vixen Everyone else seems to i nexperiencedunestablished to become JSA members at the very beginning . Like later joining of Jesse , Wally , Cisco , Caitlin , Rene , Rory , Curtis , Monel , James , Alex , Mick , Snart if they ever bring him back , the Hawksif they ever bring them back Steel , and Rip would have been totally acceptable and plausible at that point . Old school vixen doesn ' t make much sense because she has to be returned to the past as some point and I ' m still not entirely sure if there ' s some twist that ' s going to redeem the characters of Helena , Artemis , Julian and Hartley who kind of disappeared , or resurrection of Eddie and Ronnie who some people believe may return as alternate flash characters , especially Eddie
