Bloodplay has the ability to shrink to around two inches tall. While in this form, she is capable of flight and can produce a small, foot-long red laser, that cuts without cauterising the wound and is quite potent, casually penetrating metal. She can use this laser at her full size, but it is weaker.
It is possible, given her name, that the 'lasers' she uses are actually pressurised blood.
Bloodplay was involved in the attack on the Wardens headquarters by the Simurgh, and was driven raving mad by the Endbringer. She attacked Breakthrough, and was physically restrained by Victoria after delivering severe injuries both to her and Byron.
She was delivered to The Mathers Giant and as a consequence was freed by the Simurgh attack. Bloodplay attempted to find Dinah Alcott inside Grue's darkness and injured Sveta and one of Rachel's dogs. Bloodplay was slammed into the ground by Sveta, and presumably put out of commission.

↑The lights went out, then came back on. In the time they’d been out, a person had moved into the center of the hallway. They wore a costume that was in the post-Gold Morning style, clothing mixed with costume, mostly red. The red was mottled with blood, to the extent I couldn’t tell what was pattern and what was costume.
Open up, I thought. Hatch me out…
I floated to the side, placing the gun on the stairs before crouching on the underside of the gun.
The woman looked at us with eyes that were red from corner to corner. Thousand yard stare. - Excerpt from Last 20.4
↑The woman screamed, struggled against strength that could lift a cement mixer, and then she disappeared.
No, not disappeared. The camera, struggling to keep up with the changes in lighting and other screwy signals, started tracing her in golden lines that lagged behind her as she dramatically changed shape and size.
She’d shrunk, from human-sized to barely two inches tall, slipping from the Fragile One’s grip. I felt her bump into the Fragile One, unable to detect where the forcefield started or stopped, then she closed in on our group. - Excerpt from Last 20.4
↑The range wasn’t much- one foot, but when she shot Byron, she cut through the armor at his forearm and penetrated flesh. - Excerpt from Last 20.4
↑Blood welled at my neck where I’d just stopped the bleeding, and then it foamed. What had been a slash of a non-cauterizing laser or pressurized blood or whatever else was opening up, parting. A dribble touched my armpit and ran down my side, and it stung like a sunburn. - Excerpt from Last 20.5
