- see Robin
An upbeat young clone said to have had human DNA altered in order to mimic Kryptonian abilities created by the Cadmus Institute. One of the three founding members of Young Justice. He started out with Tactile Telekinesis as his only superpower but slowly began to develop more of them with age. He is best friends with Tim and Bart and eventually starts a long term relationship with Cassie.
Kon started out his career working for Cadmus as a Hawaiian superhero housed by the organization. After a number of changes for the worse in the company he was invited to live with the Kents in Smallville and modified his costume to a more sleek look with fingerless gloves instead of his bulky red ones.
Following the dissolution of Young Justice he joined the Teen Titans along with the rest of the "core four" (Cassie, Tim and Bart) and learned that instead of being a human clone with modified DNA he was actually a clone made using the Kryptonian DNA of Superman and the human DNA of Lex Luthor.
The yellow eyed impulsive speedster and grandson from the future of the Silver Age Flash, Barry Allen. Imp is one of the three founding members of Young Justice, and the youngest and most cheerful member of the team with perhaps the oddest thought process.
He lives with and is mentored by the Golden Age speedster Max Mercury (Quicksilver) who acts as a Parental Substitute for Bart.
The Adorkable Plucky Girl daughter of museum curator Dr. Helena Sandsmark and president of the Gateway City Wonder Woman Fan Club who was granted powers by the Greek gods in recognition for her bravery after she "borrowed" the magical Gauntlet of Atlas and Sandals of Hermes from her mother's exhibits to help Wonder Woman out in an emergency.
Wonder Girl was one of the first six members of Young Justice joining at the same time as the two other girls in the original six, Secret and Arrowette. Cassie became the second leader of the team following Robin leaving the position after the team lost their trust in him when Batman's plans to take out the Justice Leauge came to light. She is the only member of the "core four" not to have their own solo series.
In her earliest appearances she was easily mistaken for a ''boy'' out of her Civvie Spandex costume with her Boyish Short Hair and preference for comfortable baggy shirts and long cutoff jeans. Over the course of the series she is gifted a pair of vambraces by Donna Troy which she adds to her costume along with adding a pair of red pants in place of the bike shorts she started with. She stops wearing her black wig as a part of her Wonder Girl outfit as she grows her natural blonde hair long enough to put in twintails as she becomes more confident in her role after being acknowledged by her predecessor. She changes her costume again after becoming the leader of Young Justice, wearing a black sleeveless turtleneck with the =W=emblazoned across the chest with red boot cut jeans which have white stars down the outer seams. At this time she also starts letting down her now much longer hair keeping it out of her face with her goggles.
Following the dissolution of Young Justice she joined the Teen Titans along with Kon, Tim and Bart and learned that her disappeared dad is Zeus. This revelation that she is a demigod means her powers were actually inherited and had been sealed in an attempt to give her a normal life before she jumped at being a hero regardless.
