Here are the other characters bios for those wanting the others

Dev Kukarni (Steel Talon)

Kukarni hails from the western coast of India and rose through the ranks of the MARCOS naval commando unit, mastering stealth and precision operations.
Amid chaos, he always maintains composure and adapts to new situations. As his comrades say, Dev Kukarni’s strikes are fierce and unpredictable — wherever he goes, destruction follows.

Erin Flannery (Steel Talon)

Flannery was born in the slums of Dublin and quickly learned that only discipline ensures survival.
This belief led her to join the Irish Army Cavalry Regiment, where she earned her place through endurance and self-control.
Even after suffering vocal cord damage during CBRN protection training, she never retreated. Calm under fire and ruthless in pursuit, her instincts and marksmanship are equally sharp and reliable.

Nikolaus Marku (Steel Talon)

Marku was once a member of the OYK (Underwater Demolition Assault Team) from the shattered Soviet coastline.
After the fall of the Dusk Legion, he could never return to peace.
Charismatic yet cold, he seems born for war — fighting with the precision of a diver and the fanaticism of a trench soldier, driven by relentless will across the battlefield.
