-- -Lunar Knight talking to Batman

Jimmy was born to a very poor family in Gotham with a loving mother and an abusive father. When he was just 7 years old his father shot his mother and then shot himself. Leaving Jimmy alone to fend for himself in the harsh world. With his knowledge of the streets, Jimmy managed to survive and go to school in the harsh streets of Gotham. Along that time he befriended a young boy who was also an orphan by the name of Jason Todd and they became best friends. At age 10 he met a man who simply went by the name of "Bone" who became his adoptive father. Bone was a Street Fighter who knew several different forms of Martial Arts, he taught Jimmy these martial arts and soon brought Jimmy with him on the Street Fighting scene. Jimmy then became a street fighter by age 11, able to beat grown men in combat because of his training with "Bone". Bone taught Jimmy both unarmed and armed combat. Being able to defeat almost any foe that was thrown up against him. However at age 16, Jimmy also lost Bone, as Bone was killed by the same man who got him into street fighting. Jimmy then met Batman, who helped him track down the man and bring him to justice. Batman saw the boys fighting skill and considered him to be the next Robin, however he also saw that Jimmy was too unstable and needed to find his own way. At first Jimmy became a young Assassin, wielding a sword into battle. He later realized that killing people is the way he would become just like his father and the man who killed Bone. He then became a young hero wielding a sword, staff, and various other weapons. He decided to call himself "Lunar Knight". After catching Batman's attention once again he was offered a spot in the Young Justice League and he took it.

Meeting The Team

Jimmy was brought into the Young Justice league after the death of Wally West. When he first entered and they asked for his name he just kept saying to call him Lunar Knight. This caused a conflict between himself and Superboy which led to an argument, which led to a fight. The fight ended up with Lunar Knight being the victor. Nightwing then broke them up and said that the last thing they should be doing is fighting amongst themselves.

Lunar Knight's first mission

Reunion with Jason Todd

After hanging out with Dick and Connor, Jimmy decided to go along home to his apartment. Along the way he saw a street gang being brutalized by the man known as Red Hood. Jimmy put his hood on and went to stop Red Hood. This led to them getting into a fight, after a long battle Jimmy kicked the helmet off of Red Hood to reveal his old friend, Jason Todd. Jimmy, shocked and surprised to see that Jason was still alive tried to help Jason but Jason rejected him and kicked him the face, Jason then left the seen. Leaving Jimmy in the alleyway.


Jimmy is exuberant, brash, inattentive, and heedless to formality or social standings. Jimmy can be sardonic, rude, and abrasive to anyone who he dislikes. He is also quick to anger, stubborn, and never misses a chance to use as much vulgar language as possible. He's hot-blooded, arrogant, brave, and strong. But Jimmy is highly optimistic person, choosing to think positive and upbeat. He is an upbeat and brash person, and although he is simple minded at times, he has a strong sense of justice. Nero is really competitive and loves to compete. He's simple minded and determined. Simultaneously, his flaws lie in his temper and impulsive nature. However, Jimmy is very quick to anger, he is short-tempered, aggressive, blunt and stands his ground, characteristics that had mixed in his fighting style.

He can be arrogant, confident, and cocky as proven in his battles. When blinded with anger, he lets go of all reason and focuses on venting his anger,as shown when he tries to fight someone of Batman's caliber. His words have bite, and he isn't afraid to speak his mind. He's also shown to be very rebellious and also pretty lazy. He's very honest, sarcastic, laid back and has a somewhat go with the flow personality. Jimmy also possesses an indomitable force of will; in situations where most others would give up and resign themselves to defeat or imprisonment, and in situations where he is severely outnumbered and outgunned, he always forges on, never loses faith in himself and never quits or submits. However, this can also lead to him being on the brink of death against more powerful opponents.

Jimmy has a lot of self-confidence and possesses a large ego to match it, making him sassy, cocky, quick-witted and sometimes overconfident in his abilities. He has a lot of attitude, shows a lot of sarcasm through his gestures and has a narcissistic tongue. He often jokes around to light the mood, but will also take any opportunity to taunt and mock his opponents, and takes many of the lesser situations he faces lighthearted. He is also not generally modest when it comes to his abilities and is very proud of his skills, smug and a showoff.

Jimmy's personality is a juxtaposition of kindness and ferocity. He is extremely benevolent and firmly stands for freedom, but he is never the one to rest in the face of injustice or oppression. Likewise, Jimmy is shown to have a remarkable capacity to forgive, forgiving Superboy after he had tried to kill him . Nero has been shown to enjoy music, but seems to have an special interest in rock music. Furthermore, it is displayed in many of his fights that Nero likes break dancing, as when he fights in hand to hand combat he will often windmill to attack with his feet. He also will often break dance when he wins in a fight.

He's a workhorse training alot so he can improve his abilities, but he's obsessive, which can make him clumsy at times. However, Jimmy is far from perfect. His short temper has been shown to get him into alot of trouble, his impulsive nature has made him fall for traps and tend to blurt things out as soon as they pop into his head as shown by when he say's "Sometimes my brain doesn't know what my mouth is saying.". He feels responsible for his friends and anything bad that happens to them. He will risk his life for his friends and even a complete stranger, this has almost gotten him killed plenty of times. Because of his adventurous attitude he cannot stay still for very long saying it "Makes him all fidgety". His overconfidence, light-heart,and adventures nature can cause him to get on his friends nerves.

Despite being a hero and a member of a branch of the Justice League, Lunar Knight will kill if he must. Though he prefers not to, if there is little other options, he is the first to suggest killing. This causes him to get flack from members of his team and at one time got him kicked out of the Justice League. He even attempted to kill the Joker, when Batman's specific orders were to not kill him.
