The stern and calculating Robin and the cocky and brazen Superboy occasionally compete for leadership; Robin is the one most commonly deferred to, though routinely teased by the others for what they consider his over-pragmatic nature, initially refusing to share his face or his true identity with any of them; a slightly jealous Wonder Girl overcomes her initial distaste for Arrowette and the two quickly become close friends; Wonder Girl's schoolgirl crush on Superboy slowly begins to develop into genuine feelings shared between the two of them for one another; the team as a whole usually find the ability to trust in Impulse in spite of his whimsical character, yielding mixed results in various adventures; Secret, amnesiac to her true identity and history, is accepted for her innocent nature and forms a kinship with Wonder Girl and Arrowette, and later on in the series she develops a crush on Robin.

This man was an aspiring super-villain bent on battling and killing young metahumans for "practice," later revealed to be Secret's adopted brother in her previous life.

Young Justice discovers and "adopts" the Super-Cycle, a sentient vehicle capable of flight from New Genesis which they come to rely as their primary means of transportation.

Writer Peter David, in a column about jokes he was not allowed to do, revealed that he had considered naming the two "Nuck" and "Futz", but had been overruled by DC editors who did not like the combination "Nuck'n'Futz".

It helps stir an already-ensuing media blitz aimed at all young super-heroes turning public sway towards the opinion that all teenage heroes are too reckless and more of an endangerment to society than a protection.

[2] In the aftermath of these events, negative public opinion against the young crime-fighters subsides, and the team reconciles with their friends and mentors in the Justice League and with the government.

The team later make an expedition to outer space at the behest of Doiby Dickles, former sidekick to Golden Age Green Lantern Alan Scott, and former member of Old Justice, to free his previous homeworld Myrg from invading forces.

Robin begrudgingly allows Young Justice to accept Lobo's help in this instance, primarily out of a desire for any chance of evening their odds for success.

After liberating Myrg and returning home (after yet another brief excursion to New Genesis, in which Secret meets and unwittingly strikes up a rapport with the despotic Darkseid), Lobo continues to exercise his presence with Young Justice and participating in their adventures for no real reason that anyone within the group can discern; he is never officially accepted as a member.

The team quickly begins drawing enemy fire; Impulse is left shaken and temporarily traumatized when one of his super-speed "scouts" (vibrational "clones" Impulse learned to make of himself that could function independently for short time periods) is killed in the line of fire, giving the lackadaisical hero a harsh confrontation with his own mortality; Li'l Lobo is all but annihilated by Parademons, ultimately finished off by the Black Racer.

The team finally makes good their escape from Apokolips in the midst of the chaos, with the help of one additional genetically inferior teenage Lobo that had remained hidden from the fight in their spaceship.

Meanwhile, in an effort to help Secret come to terms with her tragic past and assuage her concerns over what she considers her "true nature", Snapper arranges for Suzie to be taken in by the Spectre Hal Jordan in a mentoring capacity.

In the end, Wonder Girl, having blossomed into a competent, level-headed heroine since her more awkward days hiding under her wig and goggles, and also having stuck with the team through thick and thin since close to its beginning, wins the election, and is given full blessings from former leader, Robin.

When Empress's father is kidnapped and murdered by her super-villain grandfather, Agua Sin Gaaz, a prominent and powerful resident of the nation of Zandia, populated primarily with criminals, Young Justice assembles a legion of young heroes from across the DCU to assist in Sin Gaaz's apprehension, including Stargirl, Jakeem Thunder, Lagoon Boy, Kid Devil, The Wonder Twins, and dozens of others.

As Young Justice prepares to boost its image and expand by agreeing to star in a new reality show, Secret learns that her father is to soon be sentenced to death for the murder of her brother, Harm.

When they refuse and later condemn her after freeing her father anyway, a betrayed Secret erupts in a fit of anger, violently attacks her friends, and agrees to leave Earth for Apokolips with Darkseid, at last giving in to his offer of tutelage.

With Secret now in service to one of humanity's greatest adversaries, and now totally in control of her vast power linking her to the abyss, the team apprehensively prepares to face their former friend.

The last page reveals that Slo-Bo, rather than being killed by Darkseid, was instead flung into the far future, where he is (consciously) imprisoned as a statue in the Young Justice of the 853rd Century's cave headquarters.

A casual business meeting with a potential money source and the Titans goes awry when the two teams are attacked by an android (see Indigo) from the future, leaving Empress, Argent, Cyborg and Jesse Quick hospitalized.

Wonder Girl, enraged at being unable to save either of them and particularly saddened by the loss of her friend and predecessor, has come to see herself and Young Justice ineffective as heroes, and turns away from her teammates.

The kids, choosing to shoulder the weight of the responsibility for the fiasco, drop out of communication with one another until Wonder Girl, Robin, Superboy, and Impulse are brought back together by Cyborg, Starfire, and Beast Boy to form the new Teen Titans.

After over a year of inactivity, Lagoon Boy is recruited by Cyborg for his new Titans East roster, only to be severely injured and rendered comatose on the team's first training exercise.

The pair would share stories about how Bart would impulsively make mistakes such as causing an international incident in Gorilla City, failing to realize his teammates were badly-made robots and publishing the team's secret identities in a Young Justice comic book.

[4][5] The first story arc featured the reunion of original team members Robin (Tim Drake), Superboy (Conner Kent), Wonder Girl (Cassie Sandsmark) and Impulse (Bart Allen).

In their effort to find out what happened to him, Young Justice teamed up with Naomi, along with Jayna & Zan from Wonder Twins and Miguel Montez & Summer Pickens from Dial H For Hero (both series also under the Wonder Comics imprint).

More allies were recruited for the mission to recover Superboy, including Spoiler (Stephanie Brown), Aqualad (Jackson Hyde), Sideways (Derek James) and original team member Arrowette (Cissie King-Jones).

The series was part of DC's kid-friendly all-ages line, which also included comics based on other popular cartoons such as Batman: The Brave and the Bold and Ben 10.

Young Justice is briefly mentioned in Gotham Knights, where Tim Drake, as one of the main playable characters, can receive messages from his teammates Kon-El, Bart Allen, and Cassie Sandsmark.

The 1,000,000 issue of the series was a part of the "DC One Million" storyline, which was a top votegetter for the Comics Buyer's Guide Fan Award for Favorite Story for 1999.

Said story involved Justice Legion T, an 853rd Century trio of young heroes: Robin the Toy Wonder (a robotic Robin), Superboy OMAC (One Millionth Actual Clone, a play on the classic OMAC character) and Impulse (a Speed Force-influenced energy being, presumably either personified by the spirits of previous persons who used the heroic name, or else the living embodiment of random thoughts lost in the Speed Force, but most probably a time misplaced Scout of the original Impulse).
