Connor Walsh -- How to Get Away with Murder
Connor from How to Get Away with Murder. Undoubtably the breakout character from the show. Connor is manipulative, sexually aggressive (in the best way possible), witty, vulnerable, and can insult you better than anyone else.
Elizabeth Lascelles -- Grimm
Elizabeth Lascelles, Grimm. Many fans had been hoping to meet Sean Renard's mother, and Elizabeth Lascelles (Louise Lombard) did not disappoint. This formidable Hexenbiest made a grand entrance by using her magic to save Renard from the brink of death; then, as a favor to her son, she helped our heroes break Adalind's spell that had stolen Nick's Grimm abilities. Elizabeth is powerful as both a witch and a woman: she is what a Hexenbiest should be, putting to shame all of Adalind's petty schemes and plots. Plus, she had some of the best quotes in every episode in which she appeared!
Trubel -- Grimm
Teresa "Trubel" Rubel. Grimm. Trubel was one of the best things to happen to Grimm this year. I mean, who doesn't love a girl who carries a machete around under her backpack? She was a breath of fresh air, having learned the hard way about being a Grimm and holding nothing back to survive. She was straightforward and badass, but still managed to be adorable and endearing.
Joe Caputo -- Orange is the New Black
Warden Joe Caputo (Nick Sandow), Orange is the New Black-Although he might have morally erred in the series finale with Fig, Caputo stepped up at Litchfield to become a hypothetical source of hope among the administration that Piper (and the audience) thought would never happen. It remains to be seen whether he will be trampled by the system like his predecessor, but for now Caputo is riding high and in a show like Orange is the New Black which tugs at the viewer's emotions, Caputo's ascension and (mostly) noble intentions were cathartic this past season.
Skye -- Agents of S.H.I.E.L.D.
During Season 1 of Agents of S.H.I.E.L.D., Skye pretty much served as the audience surrogate and seemed to have little purpose other than to get into trouble and do Computer Things. By the time Season 2 rolled around, however, Skye graduated into a full-fledged agent, beating the stuffing out of HYDRA goons and fending off (and manipulating) the creepy stalker attentions of crackerjacks crazy Grant Ward. Skye's insight was instrumental in figuring out the mystery of the alien writing that was consuming Director Coulson. In the mid-season finale, Skye finally learned the truth about her origins (as well as her real name: hello, Daisy!) and met her homicidally insane father Cal. As if to reinforce her evolution as a character, the episode concluded with her coming into supernatural (dare we say, Inhuman?) abilities, courtesy of the Obelisk/Diviner
Grant Ward -- Agents of Shield
During the first half of Season 1 of Agents of S.H.I.E.L.D., fans accused Grant Ward of being bland, vanilla, boring, and just about every synonym meaning "not interesting." Then The Winter Soldier happened, and it was revealed that Boring Ward was a mole for HYDRA! But the situation wasn't even as simple as that, as Ward wasn't actually loyal to HYDRA at all. He soon grew into a much more complex and unpredictable character, developing an obsession with Skye that hinged on stalker-creepy (to the point where she actually shot him to get away from him), but a large number of fans agreed that Ward was now far more fun to watch.
