Beros

A green hooded cape marks Beros in the field, red arrow fletching pinned to its left side. Mint coloring runs through both her cropped hair and her keen eyes. The lower half of her face stays hidden behind a mask, and her frame is that of an athlete.

Her gray sleeveless combat suit follows the same pattern worn by Rogone and Sidero, though the mask is hers alone. A white quiver rides her back, holding whatever she intends to fire. She finishes the outfit with heavy cream boots, a burgundy glove on the right hand, and matching material wrapped around the left index finger.

Humarise doctrine sits at the center of everything Beros does. She accepts Flect Turn's goal of erasing Quirks from the world and will endanger bystanders or kill outright to move it forward, untroubled by the wreckage. Because a Quirk manifested in her too, she frames her service as penance, pledging loyalty and her own survival alike to her master's cause.

Betrayal earns nothing from her. When Sidero gave himself up and offered the Heroes information in trade for his life, she answered by shooting at him.

Beros enters events chasing Alan Kay, who has fled with a briefcase holding the master key capable of disarming every Trigger Bomb Humarise planted, the single threat to their plan. Flect Turn sends her to retrieve it and end him. She runs him down on a motorcycle and puts arrows through his car until it wrecks. Her Quirk, Longbow, reshapes her left thumb and pinky into the ends of a bow; she guides whatever she looses so it homes on a target, with force enough to punch through a vehicle, but she cannot produce her own ammunition. The case falls from the highway and is swapped by accident with one belonging to Rody Soul, whom she watches disappear into the subway.

Cracking the case open in an alley, she finds stolen jewelry instead. Flect orders her to keep hunting and repeats that surrendering her life is her sole route to atonement for the sickness of carrying a Quirk. She resumes the chase after Rody and Izuku Midoriya, opening fire from a distance while police pursue the pair. Izuku evades her with Blackwhip, saves Rody, and gets away with the briefcase again.

Rody later tries to hand the case to the authorities so he can get home to Lala and Roro, the younger siblings waiting on him, only for Rogone to decide the young man knows too much and move to silence him. Izuku intervenes, Beros arrives shooting, and an arrow meant for Rody hits Izuku in the chest, blunted by the phone in his pocket. A smash attack drives her back. Days on, at the Klayd border, she and Sidero strike from a helicopter, Sidero feeding her his Iron Ball Quirk as ammunition until the mountainside is torn apart. Shoto Todoroki freezes Rody clear while Katsuki Bakugo wrecks the aircraft with Explosion. Out of arrows and told to come quietly, Beros shuts off her Quirk, recites the Humarise line about humanity's salvation, and steps into open air as the helicopter slams into the cliff and burns. What became of her is left unresolved.
