Princess Komand'r, also known as Blackfire on Earth, is a supporting antagonist in Cartoon Network's Teen Titans. She is the older sister and arch-enemy of the the Titan member Starfire (Koriand'r) and Wildfire (Ryand'r) and the eldest child and daughter of King Myand'r and Luand'r. She strives to rid of her sister by any means necessary and does everything to destroy her sister's confidence. However, Starfire officially disowns her sister upon learning Blackfire teamed up with Madame Rouge to shapeshift into hers and Blackfire's brother .
- It is revealed in the Teen Titans Go! Comics that Blackfire sold her sister to the Gordanians. This eventually led to Starfire's escape to Earth and her eventually meeting Robin, Raven, Cyborg and Beast Boy. This caused the group to form the Teen Titans as they defended Jump City from the alien invaders while saving Starfire. This means Blackfire is indirectly responsible for the the team's formation and the events of the TV series.
- She is the only arch-enemy of a Titan to not be the main antagonist of a season. Slade, Brother Blood, Trigon, and The Brain were the archenemies of Robin, Cyborg, Raven and Beast Boy and the main antagonists of the first two seasons, season 3, Season 4 and Season 5.
- Had a sixth season been produced, Blackfire could have been the main antagonist, as it was also going to involve Starfire.
- She is also one of the two arch-enemies to be related to the main Teen Titans team, more specifically being Starfire's older sister. The other includes Trigon, who is Raven's father
