Kelsey Leigh

Bursting onto the scene in the landmark Avengers #500 — Brian Michael Bendis and David Finch's seismic 2004 story that shook the Marvel Universe to its core — Kelsey Leigh is a Modern Age figure whose debut couldn't have been more dramatic. Her story winds through the pages of New Excalibur and The Avengers, placing her in remarkable company alongside icons like Captain Britain, Iron Man, and Captain Marvel. Though her catalog footprint is relatively compact across an 18-year span, the weight of her debut issue alone marks her as someone worth seeking out — Avengers #500 is one of Marvel's most consequential single issues of the modern era, and being woven into that moment gives Kelsey Leigh a genuine place in comics history.
