Blackfire (real name Komand'r) is the firstborn eldest daughter and princess of the long-dead King and Queen of Tamaran and the older sister of Starfire and Wildfire. She is the former Grand Ruler/Empress of Tamaran and serves as Starfire's arch-nemesis and an enemy of the Teen Titans.Blackfire is shown to be a tall, beautiful girl. Blackfire has tan skin; angular, dark-violet eyes; and small, rounded, violet eyebrows. She appears to be wearing black eyeliner as well, or it could be that her eyelashes are naturally very thick. She also has shiny, straight, waist-length, black hair with short bangs. Compared to Starfire's outfit, Blackfire's outfit acts more like full-body armor with a black crop top, mini-skirt and thigh-high boots. But this is considered as Tamaran's prisoner uniform, similar to the one Starfire wore in the episode Go!.Even though Blackfire is Starfire's older sister, the two are polar opposites as Blackfire is grim, cunning, deceitful, immoral, sadistic and unremorseful who also has the optimum qualities of a villain. The two almost never get along well, except when Blackfire tricks Starfire into thinking she's being nice. Blackfire is constantly trying to, in some way,do away with Starfire, first with getting her arrested and then trying to marry her to an ooze alien. Blackfire loves fighting her sister and rubbing the fact that she is older and stronger in her little sister's face. The two of them are poster children for sibling rivalry. She has a very sarcastic sense of humor and always hurts Starfire's feelings. Blackfire is also quite vain and loves telling stories about herself. Blackfire is also quite pretty, and she knows it and uses it to her advantage when around boys. This is seen in the second episode, "Sisters" when she developed a crush on Robin upon meeting him and tried to gain his attention and affection, but this could also have been a ploy in further isolating her sister from her friends. Blackfire is vengeful, ruthless, and treacherous as she has never appreciated Starfire and has always bullied her since their childhood. She also doesn't regret denouncing Starfire for being her biological sister. Furthermore, Blackfire is manipulative, willing to pretend to spend quality time with Starfire, only to betray her sister by allowing the Tamaranian Drones to arrest Starfire as a means to escape her imprisonment. She never realizes her crimes until she has to face the consequences, namely when Starfire punished her twice
