Kestrel
Kestrel is a demonic villain who serves as a major antagonist in the Hawk and Dove series, a powerful agent of chaos opposing the avatars Hank Hall and Dawn Granger across their adventures.
Emerging from DC's late-1980s Copper Age revival, Kestrel made their mark with a debut in the very first issue of Hawk and Dove in 1988 — a collector-significant launch that set the tone for the series. Over a compact but memorable run through the early '90s, Kestrel carved out a niche in DC's universe as a recurring presence in the world surrounding Hawk and Dove, sharing pages with Hank Hall, Dawn Granger, and the enigmatic Flaw. It's a tight, focused corner of the DC cosmos, but for fans of that edgy Copper Age energy, Kestrel is exactly the kind of character who rewards a deep dive into the long boxes.
