STARFIRE

Starfire is an alien super-hero with powers of flight and energy projection. Born a princess on the planet Tamaran, she escaped execution at the hands of her older sister Blackfire and traveled to Earth. Meeting the Teen Titans, she became a charter member and stayed with the team for most of her career. Her culture's different standards of intimacy cause her to be extremely open and sexually liberated by human standards. She has also been a member of the Justice League, Outlaws, Outsiders and R.E.B.E.L.S..

Presumably because English is not her first language, Starfire speaks without contractions, and misuses idioms (e.g. "Kick the butt!" as opposed to "Kick butt!"). This also may be due to her being Tamaran's princess and future queen--she cannot forget her manners that she learned in the palace. Additionally, she uses several Tamaranian nouns, such as "bumgorf" (parental term of endearment or simply my child or sweetie), "K'norfka" (parent or guardian), and "shlorvak" (dream).

Starfire is naive and somewhat insecure, but her naivete is not to be mistaken for stupidity. It is this naivete that endears her to others, especially to Robin, who occasionally shows signs of romantic interest in Starfire. An alien and an outsider, she is still rather new to Earth and its customs.
Starfire takes friendship very seriously, and is easily distressed when others, especially her friends argue or fight. Like all Tamaranians Starfire can fly up to speeds that are ten times faster than light. Stafire can project bright green glowing circular bursts of "starbolt" energy from her hands (including her fingers). Starfire also has the incredible ability to survive in the vacuum of space without any sort of protection or survival gear. Starfire, like many Tamaraneans, is allergic to Metallic Chromium. When she sneezes, she unleashes her bright green glowing starbolt energy out her nose and mouth which is highly destructive.

SUPERBOY

Superboy is a clone grafted with Superman's DNA (as opposed to a younger version of Superman), who was introduced in 1993. He was created by Project Cadmus to replace Superman following the Death of Superman story, and was artificially aged to mid-teens and implanted with the necessary knowledge of someone his biological age (in regards to general studies, such as math, reading, etc). Before the experiment could be completed (i.e. aging him to full adulthood and implanting him with safeguards to control him), he was freed by the Newsboy Legion and escaped. One of the boys gave him a leather jacket before he set out into the city (having his first brush with being Superman when he encounters Sidearm attempting to rip off an ATM). When Superboy arrived in Metropolis, he went by "Superman" and had no real name. While glibly asserting he was the original Superman, he quickly rebuked any insinuation he was the original Superman. In fact, he told anyone who'd listen that he was a clone of Superman. Superboy loved the limelight, but was not particularly cautious at first. Steel had to have some words with the Kid about not trying to be Superman just for the glory after Superboy's carelessness inadvertently led to the death of a Daily Planet chopper pilot.
Superboy is approached by Supergirl to work with her at LexCorp. Superboy and Supergirl work together to save lives, pulling many people from cars that fell into the river, before Supergirl is left with the unhappy job of telling Luthor that Superboy turned down his offer.
Superboy was a founding member of the team Young Justice, along with Robin (Tim Drake) and Impulse. The team formed after the three boys decided to have a "camp out" in the old JLA Justice Cave, where they encountered Red Tornado (who agreed to keep an eye on them)
Superboy is a clone of Superman and Lex Luthor, as such he is both Human and Kryptonian. This affords Superboy with telekinetic abilities as well as an alien physiology. Although some of the abilities are subject to change due to age and gene manipulation below is a list of exhibited superhuman abilities. uperboy's human DNA was physically altered to allow him not only advanced brainpower but actual telekinetic powers. Visible only in the form of red wavelengths emanating from Superboy and the subject of the telekinesis; his ability allows him to fully lift and manipulate objects in any way his mind can think of. His power is not always on and he must think about each move before he can make it. He's exhibited his telekinetic ability in many creative ways.

RED ROBIN

As a small boy, Timothy Drake attended the circus the night the Flying Graysons were murdered. A few years later, he saw footage of Batman and Robin apprehending the Penguin. Robin performed a quadruple somersault, a rare maneuver that only Dick Grayson and a few others could perform. After learning Grayson was the ward of Bruce Wayne, he came to the conclusion that Wayne was Batman.

Tim continued to follow the adventures of the Dynamic Duo, as well as Grayson becoming Nightwing and Jason Todd succeeding him as Robin. After Jason's death, Timothy became convinced that a replacement was needed. Tim had his doubts about becoming the new Robin, but Bruce told him that he had every confidence in Tim being his new partner. Bruce also confided in Tim that he was looking for someone with smarts, not just guts, and Tim had that and more. All that was necessary was that Tim go through some intensive training before taking to the streets in Gotham.

Much like Dick Grayson, Tim Drake has allied himself with the other superheroes in his age demographic. He mostly worked with the Gotham City heroes, but on occasion joined forces with other heroes such as Superman, the Flash, Superboy (who became Tim's best friend) and Impulse. Tim possesses no known superhuman powers though is suggested to have a far beyond normal mental concentration and mental focusing ability that allows him to think and calculate beyond most human beings. Through continuous intense training, Tim possesses peak level strength, stamina, speed, reflexes and agility for a teenager.
