5) Artemis
Can I go on the record and say that the popular Young Justice character was on my list before the announcement that her character-pseudonym, at least, would be joining the crop of characters in season five of Arrow? Seriously, she was, and now I’m even more certain she should have been one to join the Legends of Tomorrow crew.
There are already too many archery masters on Arrow and, in all frankness, the show is quite obviously far from performing its best after season four’s disappointing and melodramatic second half. More than anything I would be thrilled to see Sara and Artemis interacting together as more practical badasses. It might also be a nice contrast to bring on a character new to the vigilante lifestyle compared to those more accustomed to the fatal risks that come along with the job.
