Most fans already knew for a fair while that Hawkman and Hawkgirl were to be a part of The CWs shared DC universe as they get set to make a big splash in Legends of Tomorrow, but we didnt know whether they would just debut in that show or make an appearance in either The Flash or Arrow first. As it happens, Kendra Saunders popped up earlier in The Flashs Season 2, but it was when she was trying to find her inner Hawkgirl that things got a little more complicated. During the Arrow half of the Arrow/Flash crossover event, Kendra is now finally on board with who she really is. Setting up a master plan involving Green Arrow, The Flash, Hawkman, Black Canary, Speedy, Diggle et al, all Kendra has to do is become Hawkgirl. Only she fluffs her lines at the most vital of moments, giving fans (and her fellow heroes) a major surprise. With Kendra bottling her big moment, her and Hawkman are quickly killed before the whole plans falls apart and the other heroes, not to mention Central City, are vaporised. Well, apart from Barry Allen, because he can run really, really, really fast.
