Starshrike can beat her wings to fly very quickly, and can emit a powerful sonic beam by screaming.

History

Starshrike is the successor of Shrike among the Cadre. As discussed in the main Cadre article, our hypothesis is that the Cadre recovered Shrike’s bracers after her death during a Suicide Squad mention then gave them to a new recruit, granting her the same powers and physical alterations.

Unlike the successors of the original Shatterfist and Fastball, Starshrike adopted a slightly different name than her bracers’ previous owner.

She was first seen when the Cadre worked for Doctor Polaris, then betrayed him when they realised what his plan was. Starshrike was also seen hanging around a bar for alien bounty hunters - presumably she and other Cadre members present were looking for work. 

When the US government started kidnapping super-criminals and vanishing them, Starshrike was among the motley crew that sought Sanctuary with the Justice League. She thus apparently avoided being deported to an alien planet. When Libra created the Society - a grand alliance of super-criminals with mystical overtones - Starshrike was among the first wave of recruits, perhaps for protection.

The Peregrine quandary

A character named Peregrine, identical to Shrike and Starshrike, appeared in 2007. Who she is is unclear. It might be a continuity error, an alternate identity used by Starshrike, Starshrike having changed her name, a successor to Starshrike (who’d thus have died off-panel)… a complete coincidence, or something else.

Peregrine had been a victim of a criminal surgery ring forcibly removing organs from superhumans and grafting them on clients. She had been captured and her wings amputated, and was treated in a STAR Lab medical unit headed by Dr. Jenet Klyburn. Peregrine was suffering from severe phantom limbs issues, making her violent.

Klyburn, who was treating other victims of the organs thieves, worked with Dr. Mid-Nite (Dr. Pieter Cross) who dismantled the criminal ring. Peregrine’s wings had been sold to a fashion model named Angelika. Like most sold organs, the wings were causing Angelika severe health issues and were likely to kill her through either tissue rejection or immunosuppressant abuse. What happened after the organ-legging ring was taken down is unrevealed. Dr. Klyburn and Dr. Mid-Nite presumably had Angelika’s stolen wings removed to save her life, and grafted back on Peregrine.

Trinity spotting

During the Trinity events, the DC Universe experienced complex reality shifts. Early on a mobilisation of superhuman defenders took place in the US after Europe vanished behind a magical force field. Starshrike publicly joined the effort, patrolling the skies and coasts.

Starshrike was not seen since, including in Cadre appearances - it is possible that she reformed after the Trinity crisis. Perhaps Dr. Mid-Nite’s efforts to save her inspired her.

Description

The stuff on Starshrike’s head is sometimes depicted as feathers and sometimes as hair, and their colour varies. Perhaps she has learned to alter her physical mutations using the bracers because she doesn’t want to look too much like her predecessor. She was once depicted wearing Shrike III’s costume, which we assume was a continuity mistake.

Personality

Starshrike comes across as a serious and realistic professional. She knows when a battle is turning south and when to retreat, and she does her homework before an operation.

In fact she seems way more sensible, reasonable and intelligent than the rest of the Cadre, and may well have decided to drop them and do her own thing.
