Name: Connor Kent(Krypronian name by Clark-Kon-El)
Superboy
He's a genetic creation constructed by Project Cadmus in a experiment called Project Kr, a process in which they're genetically cloning a weapon that they could use to combat against Superman. It was based on Project Prime, an earlier attempt to clone Superman. Because of the incomplete DNA sequences, "Prime" was deemed a failure, a mistake they did not repeat on Project Kr.
For this new project, gaps in the sequences were filled with human DNA, with classified source as the donor. He was kept in a containment pod along with three G-Gnomes, who telepathically controlled him and educated him with the knowledge of a boy of his physiological age.
He was discovered by Superman, Supergirl, and Lois Lane when they were investigating Cadmus. Head scientist Mark Desmond attempting to stop them by using a vial that caused him to turn into a horrifying monster named Blockbuster. With Superman and Supergirl fighting him they distracted Blockbuster long enough for Lois to free Superboy. When he awoke he became enraged then attempted to attack Lois, she managed to persuade him to help Superman and Supergirl in saying it's what Superman would do. That caused Connor to help Superman and Supergirl defeat Blockbuster and escape the facility as it was collapsing. While outside, Connor looked up at the sky, commenting how it's the first time he's ever seen the stars and the moon above.
Clark convinced Lois that taking him in and helping him adjust would be better than him being taken in by the government. Lois agreed then Clark adopted him and named him Connor Kent, also Kon-El as his Kryptonian name. Supergirl helped him with his powers while Superman helped him adjust to the usual everyday life. There were some good days and really rough days with him. Also, at first, Lois was rather awkward around him ever since their first encounter but in time she cared for him as much as Clark and Lois have. Once the adoption settlements have been arranged Connor is officially a member of the Kent Family, Lois even managed a created background for him incase someone decided to look in his history. John and Martha, when he met the two, liked Connor instantly.
Clark, not wanting him to feel completly isolated from everyone, introduced him to members of The Team. Connor felt a little uncomfortable at first as he never really interacted with anyone outside of The Kents, and Lois and Chloe. He managed to get along well with Dick who was the first among the team to socialize with him when he didn't feel like socializing at the time. He even joined The Team in his first mission against Intergang and fought Amazo, his first tough opponent. After that battle Connor felt that he belong to the team.
While still pretty much the lone wolf of The Team he had his real taste of teamwork when he and his comrads were up against a 5th Dimensional being known as Mr. Mxyzptlk who forced him and the others in a life or death game show like competition. It was then that Connor had eventually gained him his first arch enemy in the Celestial Puppeteer.
Miss Martian is another member of The Team that Connor became close friends with and the battle against Mxy drew the two even closer. So the two ended up having a 'double date' with Robin and Zatanna which actually is a stakeout mission to investigate Intergang. They defeated them and learned the identity of their employer. Brainiac. The four ended up having an actual date after that but Connor and Megan finded the situation a little awkward and peacefully broke it off as they decided they're better off as friends.
In October 27 of 2005 marked the single most important event in Connor's life. Connor was hanging out with Aqualad, and Kid Flash till they're greeted by three members of the Legion of Superheroes, Cosmic Boy, Saturn Girl, and Chameleon Boy. They requested their aid in stopping Brainiac from killing teen Clark Kent thus stopping him from becoming Superman. Took no hesitation on Connor's part to agree. Him, Aqualad, and Kid Flash traveled with The LOS to the past and they stopped Brainiac from killing Superman. Clark even team with them to defeat Brainiac. The LOS collected the fragments of Brainiac then, in a effort to ensure the timestream isn't disrupted, mindwiped Clark. The LOS returned Connor and the others home but not without giving them LOS rings as they're considered honorary members. The battle in Smallville was on Connor's mind. To him it felt great actually teaming with his dad, despite that he's a teenager, and when Megan had returned from her own mission he informed her that he finally found a hero name to call himself. Superboy.
In June of 2007 Connor encountered a visitor who explained was from another dimension and was fleeing from a interdimensional assassin named Executioner. The two of them teamed up and took him down, Connor used his ring to contact the LOS and send him back to his own timeline. When it was all over he introduced the visitor, who revealed herself as Kara Zor El of Earth 2 but also goes by the name of Power Girl, to Superman and this dimension's Kara Zor El. In which Connor teased that Kara has a twin sister now. A comment in which Kara accepted. Him and Power Girl have bonded, infact Connor even developed a protective streak towards her. Which Wally discovered when he tried to make a pass at her. He has learned to tone it down but lord help anyone who tries to hurt her.
Connor had formed a new relationship with Raven whom, like him at the time, was adjusting ever since being summoned. Connor has been helping her with that while Raven in return helped him in protecting his mind from being invaded by psychic attacks.
Connor has aided the team in various missions, either it's on earth, or in space. Gained some new enemies in Project Prime, Kon-Prime, the back and fourth battles with Mxy, The Order of Chaos(A band of mystics working for The GoD), Nyx, and various others. He also had a unfortunate discovery concerning his weakness with magic when battling Nyx. While he lack the full powers of his father and cousins, he only has strength, super speed, super senses, and invulnerability, his past experiences have inspired him to become even stronger and has emurged a different person than the person he was when he first meet the team.
He has even earned himself a reputation when he would do some solo missions. He has helped a group of New Gods known as The Forever People and had aided the LOS in a mission. Also had his first spiritual encounter with the lord of evil himself Trigon.
Note: Connor was traveling with the LOS at the time when Connor was battling Doomsday
He had a face to face encounter with Clark Luthor when he first entered his dimension. Some of the others didn't notice at first but Connor knew the person before him isn't his father and he helped the others fight him off before the actual Clark arrived.
Around 2011 he was there for Dick and Barbara when they're going through the event that led to Joker crippling Barbara for life.
In 2012, just around new years eve, Raven was controlled/manipulated by Klarion and Nekron into releasing Trigon and bringing hell on earth. Thanks to help from Zatanna he helped Raven break free from their control and they joined with the others in stopping what the news media referred to as a Global Apocalypse. After the victory and when the heroes collected themselves during the stroke of midnight both hero teams celebrated the fact that not only they won but ensured the survival of Earth. Connor and Raven concluded the celebration of the new year by embracing eachother in a kiss.
Around 2015 Superboy has gotten a new costume and both him and Raven have gotten serious in their relationship. Superboy is now incharge of training new recruits.
Long ago Connor was just a project in a test tube isolated from the outside world, now he's a member of the most powerful family on earth and a member of the most promising super team the world ever has.

He already has a family and may God help any who threatens to harm them
