1 of 31Kate McKinnon (2012-present)
McKinnon made a splashy debut playing Penelope Cruz in a hilarious Pantene commercial alongside Sofia Vergara. Although McKinnon has made a name for herself impersonating stars such as Ellen DeGeneres and Billy Jean King, she is also responsible for strong original personalities like the drunk Sheila Sovage. Her camaraderie with fellow new cast member Cecily Strong harkens back to the days of Amy Poehler, Tina Fey, Maya Rudolph and Kristen Wiig.
