Odo

Odo is the chief of security from Star Trek: Deep Space Nine. He is a changeling (a shapeshifting alien).

Appearance
Odo has pinkish-brownish skin, slicked-back, brown "hair", and his "clothes" are actually part of his body but he normally looks like he's wearing a brown coat, a darker brown shirt, brown pants and brown boots.

Personality
Odo has a strong sense of justice, so he disapproves of people breaking laws/acting immorally. He likes his job and is generally very good at it, but dislikes being told how to do it (because he's a rather unconventional security officer). He is also quite serious and aloof, sometimes being rude, especially to Quark, who he even claimed to hate once. He likes shapeshifting and seems to especially like turning into birds, but doesn't like being told what to turn into (he especially doesn't like being told or asked to turn into furniture or food). He and Kira Nerys are sort of dating, but in general, Odo doesn't really see the point in romance. He also cares passionately about order and thinks it's "chaotic" if his furniture is a few centimeters out of place.
