Detective Rosa Diaz (Stephanie Beatriz), Brooklyn Nine-Nine
Next to the strict, no-nonsense Capt. Holt, Rosa is the most intimidating and mysterious member of the team, which also makes her one of the most intriguing. While some might find her anger management issues and complete distaste for smiling off-putting, plenty of others love a tough girl — and they don't get much tougher than Rosa. Although she may be a little icy at first, her co-workers can attest to her deep loyalty and, under those badassleather jackets, a kind person.
