ROBIN

For many years, Richard "Dick" Grayson was Batman's sidekick Robin.The name "Robin the Boy Wonder" and the medieval look of the original costume were inspired by the legendary hero Robin Hood, as well as the red-breasted American Robin, which continued the "flying animal" motif of Batman. Young Dick Grayson was born on the first day of spring. His mother nicknamed him "little Robin". Dick Grayson was a twelve-year-old circus acrobat, the youngest of a family act called The Flying Graysons of The Haley Circus. Dick joined the act at a very young age, having been trained in acrobatics from birth.

The formation of the Teen Titans mainly happened due to the sidekick's mentors making them feel lesser of themselves, which they quickly knew wasn't right about them. Together, they cured the heroes from their mind control; later, their mentors (Batman, Flash, Aquaman, and Wonder Woman) supported the idea of the teens becoming a heroic group, the Teen Titans! Dick became the leader of this team.
Dick continued his adventures with Batman, and began attending college at Hudson University. Robin started to take on solo missions as well, and found himself to be a capable crime-fighter in his own right. Shortly afterward, the mysterious Raven summoned Dick Grayson, and several other young heroes, to form a new group of Titans. Robin again resumed leadership, and moved out of the shadow of the Batman.
Dick rediscovered his self-worth among the Teen Titans. Batman, however, was less than pleased. He informed Dick that if he no longer wanted to be his partner, then Dick would have to retire as Robin.
Dick Grayson has almost reached Batman to a point and is believed literally and figuratively to be his successor. Dick Grayson possesses the peak human strength of a man that has intense physical workouts at the height and weight of 5'10" 175 lbs. He is able to lift at least twice his own body weight; enabling to press lift 350 lbs.

SUPERMAN

Superman is one of the most powerful beings on the planet Earth, an alien immigrant named Kal-El from the planet Krypton who was raised in Smallville, Kansas to become an American super-hero. Raised with high moral ideals, he uses his incredible strength, speed, flight and various other powers to fight evil and protect the innocent. In his civilian identity he is Clark Kent, a mild-mannered reporter working for the Daily Planet in Metropolis. He is a founding member of the Justice League of America and a charter member of the Legion of Super-Heroes in the 30th Century.
Superman's enemies would include both the supernatural and the science fictional. Lex Luthor is probably his greatest foe. Arguably Superman's greatest foe, however, apart from Lex Luthor is Brainiac.
Superman is commonly seen as a brave and kind-hearted hero with a strong sense of justice, morality and righteousness. He adheres to a strict moral code often attributed to the Midwestern values with which he was raised. His commitment to operating within the law has been an example to many other heroes but has stirred resentment among others, who refer to him as the "big blue boy scout." Superman can be rather rigid in this trait, causing tensions in the superhero community, notably with Wonder Woman (one of his closest friends) after she killed Maxwell Lord. To protect his secret identity, Superman has constructed a persona in his civilian identity as Clark Kent. To the world at large, Clark is a mild-mannered and clumsy person. Only Lois Lane, his wife, knows that this attitude is just an act.
Some of Superman's notable ability are the following: Superhuman strength, Invulnerability, Superhuman Stamina, Flight, Superhuman Speed, Superhuman hearing, smell, sight, super scream, Super breath, Heat Vision, and X-ray Vision.

BATMAN

Batman is the superhero protector of Gotham City, a man dressed like a bat who fights against evil and strikes terror into the hearts of criminals everywhere. In his secret identity he is Bruce Wayne, billionaire industrialist and notorious playboy. Although he has no superhuman powers, he is one of the world's smartest men and greatest fighters. His physical prowess and technical ingenuity make him an incredibly dangerous opponent. He is also a founding member of the Justice League and the Outsiders.
Bruce Wayne swore an oath to rid the city of the evil that had taken his parents' lives. He spent his youth traveling the world, training himself to intellectual and physical perfection and learning a variety of crime-fighting skills, including chemistry, criminology, forensics, martial arts, gymnastics, disguise, and escape artistry.
Batman's presence in Gotham City generated a new breed of criminals, no longer the simple thugs and gangsters involved in Gotham Organized Crime, but more dynamic personalities.
Batman, in most of his incarnations, is a dark and grim hero with a personal vendetta against criminals.
Traumatized by the death of his parents, Batman has sworn to rid Gotham from the criminal elements that took his parents from him. He is very paranoid and obsessive, which often makes it difficult for him to trust other people that aren't Alfred, the Robins, or the Batgirls.

Despite this, Batman has proved to have a great love for humanity, which was instilled by his parents. His father was a doctor, while his mother was a crusader against child abuse. Indeed, Batman's oath of vengeance is tempered with the greater ideal of justice. He refrains from killing, as he feels this would not make him any better than the criminals he fights. He is also a very prominent member of the Justice League and the founder of the Outsiders.

To protect his secret identity, Batman has constructed a fake persona he can use in his civilian identity. To the world at large, Bruce Wayne is a self-absorbed, irresponsible playboy and philanthropist. Only his closest allies know that this attitude is just an act.

The Bruce Wayne/playboy aspect of his character is a facade, while the masked and particularly dark, grim vigilante is marked as the "true" man.
