Batman

Batman, otherwise known as Bruce Wayne, is a crime-fighter from Gotham City who rose up to fight criminal essence that plagued the municipal.

Alfred Pennyworth
Alfred Pennyworth is Bruce's legal guardian, and the two have a lingering trust with each other. A former member of MI6, the British Secret Service, Alfred retired from the world of espionage and took a job as a butler and bodyguard for Dr. Thomas Wayne and his family. After Bruce's parent died, Alfred promised to watch over him, and has kept his promise for years. After Bruce took on the life of a costumed crime fighter, Alfred took on the role of a friend and confidante to his employer, helping track down leads and examine evidence from the Batcave while Bruce worked in the field.

Although, they were not always able to see eye-to-eye, mostly in regards to Bruce's double-life as the Batman. Alfred is very protective towards Bruce and he was not comfortable with the fact that Bruce felt his duties were to protect Bruce Wayne and not his alter-ego. Alfred openly voiced his disapproval regrading the matter to Bruce, on several occasions, though was never able to get through to him. However, their relationship strengthened when Alfred was accidentally captured in Bruce Wayne's place by Professor Pyg and Mister Toad. In the aftermath, Bruce came to the realization that Alfred couldn't protect him without protecting Batman, too. As Alfred's leg injury heals, he, being incapacitated and knowing he won't be around forever, employs Japanese warrior Tatsu Yamashiro to take over his role as Bruce's driver and bodyguard.

James Gordon
Batman's relationship with Gordon is on sour and extremely unfriendly terms. Gordon is distrustful of Batman, believing that he is a criminal. Though the two are on the complete opposite sides of the law, they stand for the exact same thing: justice. Batman is far more willing to work with Gordon than vice-versa. The night when Magpie is captured, Gordon catches up with Batman and they have a brief conversation. Batman queries how sending Magpie back to Blackgate Penitentiary is justice; Gordon brushes off his concern in a show of indifference, but rationalizes that it is the law. Batman asks, if he is captured, will he suffer the same fate. Gordon replies that he will indeed, though some other time.

Thomas and Martha Wayne
Thomas and Martha Wayne were Bruce's parents who died early on in his life, being shot in an alleyway right before him. Their death had a profound effect on Bruce and is the reason he became Batman.
