Raptor

Youth + Becoming Raptor
Raptor's true name and background is hard to pin down. But what is confirmed is he was part of the Circus. And at one point had a very close bond with Dick Grayson's mother, Mary. At some point, it isn't clear when, Raptor turned to crime. Slowly building a very well known reputation as a man that could get any job done.

Batgirl & Nightwing
Raptor accepted work in Gotham City, working under Scarecrow. Helping to keep a strong grip on Scarecrow's newly established turf, where he was developing new drugs. When Batgirl and Nightwing came around to investigate, he warned them to stay away. Telling them, he was on their side before fleeing after a brief skirmish. A few nights later he confronted Batgirl on her own. This led to a very intense brawl between the two. The brutal confrontation ended in a standstill, Raptor fleeing on his aircraft. But Raptor made his distaste for the wealthy and powerful clear in this encounter. Arguing about the way the Bat Family ignores the poor and needy until they need saving.

During a drug deal between Scarecrow and Sal Maroni, Batgirl and Nightwing bust in, attempting to take down each crew. During the course of this, Nightwing is almost shot by Scarecrow. Raptor jumped into the path, taking the bullet for Nightwing. The duo saved Raptor from there carrying him out. Bleeding heavily, Raptor told them to use his gauntlet, Suyolak to help him. Nightwing realized Raptor was a former circus performer then, deepening their bond further. Nightwing took Raptor to his home to recover but Raptor slipped out prompting Dick to look for him.

When Nightwing found Raptor, Raptor attacked him. He'd become more and more angry with the fact Dick Grayson was taken in by Bruce Wayne. This led to Raptor making his move to take revenge and free Dick from this perceived prison. Raptor kidnapped Bruce Wayne from a press conference when he couldn't fight back. Raptor had deduced Bruce Wayne's double life when looking deeper into Dick Grayson's own life. He held Bruce captive at the old circus grounds. Batgirl and Nightwing appeared to save their mentor. During the course of the long fight that ensued, Lucas Fox appeared to help the duo. Eventually, one-on-one, Nightwing was able to take down Raptor.

Before being transported to Red Sun Prison, Raptor spoke with Dick one last time. Confessing his desire to save him and his love for Dick's mother. Raptor also reported he had incapacitated Scarecrow as promised. Scarecrow's warehouses exploded in the distance after this revelation.
