Gotham City is a different place in this reality. Bruce Wayne is but a humble middle class child, 11 years aged when his father Thomas is accused of Cooperate Espionage, while really he was approached by his own employer, Jack White the billionaire CEO of White International, to spy on competition through bribery and sometimes extortion.
On the run, and hell bent on proving his innocents, Thomas Wayne breaks into White's office and is caught in the act by White himself Thomas failed to realize White had a sinister side, and there Jack White revealed his wife Martha, and Bruce captured and tied to chairs. White then kills Martha in front of Thomas and in a rage, Thomas attacks White and in the scuffle White sustains injuries to his face, and Thomas is killed in the struggle for the gun.
Gotham P.D. Lt. Gordon had been investigating White, suspicious of his involvement in the Wayne case. Because White's office was bugged a group of G.P.D. officers were on site and find Bruce before White has the chance to silence him. However, this only a slight hick-up in otherwise easily avoided murder charges. White Simply claims the Wayne's had snapped, and Thomas and Martha had dragged there son into their madness while trying to set him up. He plead self-defense.
Jack White, scarred from his encounter with Thomas Wayne got a taste for the theatrical and soon cooperate crime wasn't enough of a thrill. he eventually dons the guise of the Joker, and begins a crime syndicate like Gotham has never seen.
Young Bruce never forgot about that night, and neither did his fathers best and most trusted friend, Al Pennyworth who was a Navy Seal that served with Thomas, now working Private Security in Gotham. He takes in Bruce and through training and study makes Bruce Wayne into the perfect stealth operative. After the reveal of the Batman, Pennyworth then acts as Wayne's home base coordinator. Bruce has chosen the symbol of the bat because he has a fear of the animals from an encounter where he was bitten by a bat in his attic as a small child. He had a traumatic stay in Gotham General Hospital for rabies treatment.
Now, as a young man, Bruce has vowed to put an end to the corruption of Jack White, and along the way becomes more than a vigilante, he becomes Gotham's Dark Knight.
