Blackfire

Blackfire (Komand'r) is the evil older sister of Starfire who makes her first appearance in Mr. Butt.

Biography
Blackfire was always mean to Starfire her whole life, even back when they were little children. When they were five, Blackfire stole Starfire's doll from her. Starfire was always nice to Blackfire no matter what she did to her. At some point in her life, Blackfire got arrested.

In the episode Mr. Butt, she escaped prison and visited Starfire at the Tower saying that her visitation was because she just wanted to see her baby sister. Once Starfire showed the other Titans, Blackfire dressed Starfire up like her and got her arrested. The other titans trained her to become a better sister after this, however, by the time Blackfire became nice, Starfire was too filled with sisterly animosity towards her. The animosity resulted with Starfire engaging in a full-scale assault on her elder sister, even destroying the doll that Blackfire returns to her in the process. She fell exhausted and unconscious from Starfire's endless onslaught, but Starfire assured the others that "they had worked things out."

Appearance
Blackfire is a teenaged girl with dark purple hair that is spiky at the bottom. She has purple eyes and pale white skin in contrast to Starfire's pale orange tone. She swears a black and silver two piece dress with dark purple gems in it.

She also wear long black and silver boots with black flames on the bottom. Though not normally visible, in Mr. Butt, it is revealed that she wears dark purple nail polish and eyeliner. Blackfire can be seen painting Starfire's nails and eyelids respectively in that color.

Her eyes and hands glow light lavender when using her Tamaranean powers of energy projection.

Abilities and Powers
Like all Tamaranians, Blackfire is capable of flying faster than light itself (an ability she did not possess in the DC comic books). Her powers are also strengthened by her emotions and feelings. She is evidently much stronger and more experienced than Starfire. Her other extraterrestrial abilities include:
 * Superhuman Strength
 * Superhuman Agility
 * Superhuman Durability
 * Superhuman Endurance
 * Superhuman Reflexes
 * Enhanced Stamina
 * Expert Martial Artist: Unlike Starfire, she is quite skilled and experienced in high-levels of alien martial arts.
 * Enhanced Combat
 * Extended Longevity: Like all Tamaraneans, Blackfire can live up to hundreds of years.
 * Outer space Survival Skills
 * Blackbolt Energy Projection: Just like Starfire, she can emit extremely powerful bursts of ultraviolet energy from her hands and eyes, which are pale lavender as opposed to Starfire's bright green ones.
 * Blackbolts: Circular blasts of light purple-colored energy she emits from her hands.
 * Blackbolt eye-beams: She also fires purple laser beams from her eyes.
 * Language Assimilation: She can fluently speak any spoken language via lip contact; practically making her self-taught and more knowledge than Starfire.

Starfire
Blackfire has never liked her younger sister, even as a young child, but in the episode Mr. Butt, she wants to become a better sister after realizing Starfire loved her all these years and broke her heart. She even returned the doll she stole from her as a five-year-old child to show she's really changed and sorry for what she has done. But Starfire still continues her revenge on her. It is unknown what their sisterly relationship is now because Starfire seemed to forgive her even though she knocked Blackfire unconscious from her revenge, stating that they "worked things out."

Robin
Robin is Blackfire's possible romantic interest, although she is mainly attracted to his rear, as she constantly calls him "Mr. Butt" and is shown to focus on it, to which Robin detests. At first, Robin is shown to strongly dislike Blackfire due to her terrible treatment of her sister, Starfire. After Blackfire takes "Sister School" seriously, Robin is shown to be much nicer and allowed Blackfire to call him "Mr. Butt" and showed concern for her after Starfire finished her revenge on her.

Other Titans
She becomes friends with the other Titans and gives Raven a makeover and talks, and gives advice to Beast Boy about sisterly love and makes Cyborg proud of her.
