21 parts Complete First story of the series of "Bat Boy Wonder".
"Reaching her side he stopped abruptly, gaping the tiny baby that was resting peacefully in her arms. Offering the child to Bruce, Diana smirked at his dumbstruck expression. Bruce held and studied the tiny human. With a small head of ebony hair messily contrasting the child's red blanket, Bruce had no trouble guessing the child's mother.
Hearing a small giggle coming from his arms, Bruce looked down. Bright cerulean eyes stared back up at him. The exact same color eyes Bruce's mother had. The same shade of blue that Bruce saw in the mirror."
Wonder Woman and Batman had been dating - or rather seeing - eachother for sometime.
That was until Diana left.
She left with the reasoning of helping her people, but a year later Bruce found out that it was the other way around as her people helped her through her problem. Her pregnancy.
It is the story of Richard Thomas Wayne as he goes through childhood and grows up.
