Robin (real name Richard "Dumbo" Grayson) is a teenage superhero and the leader of the Teen Titans. He was originally a child growing up at a circus where his parents, the Flying Graysons, worked, but was adopted by Batman following the murder of his parents. Batman trained him to be a fighter, detective, and host of medium-sized holiday gatherings. He served as his sidekick up to his teenage years where he left Gotham City for Jump City and joined the Teen Titans.
Robin is a vigilant and born leader who knows when to do the right thing due to his training with Batman, thus being capable of maintaining control and order over the Teen Titans. However, these traits can occasionally go to extremes due to his traumatic past with the circus animals and his parents' deaths. He has an extreme sense of pride and ego except when it comes to Batman, who Robin is deeply afraid of, shown when he targeted Mammoth due to his size., and when he refused to let Beast Boy be better at something than him. As a romantic, Robin is nervous about admitting his feelings toward Starfire, but does have questionable traits shown when he was snooping around Starfire's room and going through her drawers. He is also quick to anger when something goes wrong, and also very self absorbed.
Robin's necessity to lead his team led to an inferiority complex due to growing frustration toward the team repeatedly brushing off his orders. His lack of superpowers has caused him to strive to be the best superhero in the world. Skilled in acrobatics and combat due to his training with Batman, Robin is a vigilant and born leader, though this occasionally goes to his head as seen when attempting to control the Titans' daily lives outside of battle.
As seen in numerous episodes, Robin tries to act as the embodiment of perfection, mostly as a hero and a male. He is quick to envy those who behold abilities beyond his own and tries to assure that he's the perfect hero, while the rest of the team is accepting to know that there's someone else who can perform better feats than they. This has led him to acting flawless on many notes and often act as though he is capable of doing things on his own. Whenever someone points out a flaw of his, he is quick to retaliate and this has led the team to not correspond with him.
Robin beholds something of a dictator attitude on some occasions and is often hard to reason with. No matter how one of the teammates tries to explain it, Robin makes it his effort to stick with his strategies and plans. This can be seen as both a good and bad thing. The good about it is that it proves Robin's leadership to the Titans but it also proves how stubborn and short-minded he can be. He is also obsessed with popularity and this obsession can ward off a few of his sanity, sometimes scaring his teammates.
Robin wears a domino mask (which are actually glasses) over his eyes. Under the mask is his true appearance, which is a exaggerated, "handsome" face. He wears a red suit with two small yellow stripes and an R symbol which represents his name. His sleeves, as well as his gloves and tights, are green. His shoes are about knee high with the leg portion colored black and the actual shoes colored grey. He has a yellow utility belt around his waist and also wears a cape which is yellow on the interior, but black on the exterior. Robin has peach-colored skin and spiky black hair.
Robin has no superpowers, a trait he feels makes him inferior compared to the other Titans. However, he does maintain an assortment of talents due to his training.
Acrobatics: Robin is skilled in acrobatics and is capable of performing flips and jumps even on a dangerous mountain terrain.
Hand-to-Hand Combat: Robin is also skilled in close combat and uses his size and slim figure to defeat powerful and large opponents like Mammoth.
Staff: Robin's Penguin based staff is his prized possession, which he sees as the most powerful of weapons. The staff itself has many abilities such as an electric claw which he uses to shock his opponents.
Accessories: Robin has many weapons stored on his belt such as birdarangs, grappling hooks, and smoke pellets which he uses to give himself an advantage in battle.
R-Cycle: Robin has a motorcycle at his disposal which he sometimes incorporates into battles.
His first attempt was a lab accident, taking Robin's vigilant and powerful genes to a normal robin. The robin turned into Super Robin, whereas Robin himself became a robin-human hybrid.
His second attempt was a form of Robin with powers of telkenisis, freeze breath, extreme speed, and laser eyes, which were all given by Raven. With these abilities, Robin stopped all world problems, thus, disbanding the Titans. His life is ruined by the cause of his powers. At his elderly age, he dies with the realization of the powers being a curse.
Nightwing is a mature and older Robin. He had a wife and and a child in Staring at the Future, however, in Sandwich Thief, he was seen as a bachelor. He has a darker voice, longer hair, and a blue suit.
Robin now has a super power to blow incredible whistles that act like Raven's dark magic.
Robin's rivalry with Kid Flash plays as an irony because the two were friends in the Golden Age comics.
In most of the episodes shown, it kind of portrays Robin becoming Nightwing when he is at least middle-aged or in his late twenties to his early thirties, especially taking consideration to each episode showing a futuristic appeal.
As seen in the majority of episodes, Robin appears to suffer with some form of dementia, noted by how irrational his behavior can be sometimes and given how some of his teammates even recommended calling a doctor or calling him crazy.
It's more than likely that this dementia is only minor, despite its advances. Reason being is because Robin can operate functionally on some occasions and even retain some sanity. However, the episode Yearbook Madness hints that later in life, Robin loses grip of his sanity and commits crimes, probably if he doesn't try to get help.
Raven and Robin are the only two characters in the show that have bird names and start with the letter "R".
