Princess Komand'r (Blackfire) is a Tamaranean like her younger sister; her physiology is designed to constantly absorb and control pure ultraviolet radiation into destructive and powerful bolts of energy which she calls "blackbolts." The radiation is then converted to pure energy which enabled her incredible feats of strength, speed, durability and the like; all on par or possibly greater than those of Starfire, having fought and bested her many times. This is not the case for flight, however, as she suffered a sickness in her youth which stripped her of this ability, but she found other means of circumventing this handicap. Being of royal blood and having fought in many wars, Komand'r also boasts impressive mortal combat skills superior even to her sibling, be it unarmed or with weaponry on hand, having battled and bested the likes of her own sibling (who is also a veteran warrior) and Thanagarian heroes Kartar Hol, Shayera Thal and Shayera Hol either in single combat or in pairs and win, as well as holding her own against the likes of a weakened Starro in his humanoid form (with some assistance from Starfire). Having undergone the same experiments conducted upon her by the Psions, Blackfire too has the ability to release her absorbed energy into incredibly powerful blasts called "starbolts". Hers by comparison, however, are considerably stronger enabling her to overpower her sister's starbolt energy. For a time Blackfire was stripped of all her powers by Hawkman using the same technology the Psions used in their experimentation upon her. Even without these strengths Komand'r is still a political activist and capable leader, being Queen of Tamaran she has access to a great many facilities, be it governmental or military in nature. Like any good politician, Blackfire is a skilled manipulator, able to utilize fear and misdirection to her advantage; even forging alliances with others despite her incredibly sociopathic nature.
