Irene Adler

A name steeped in mystery, Irene Adler made her comics debut in 1997's X-Men #1, brought to life by Fabian Nicieza, Reinhard Schweizer, and Andy Kubert under the Panini Deutschland banner — placing her squarely in the modern era of comics publishing. With appearances spanning nearly three decades across X-Men and Die furchtlosen X-Men, she's a figure who has quietly endured, sharing pages with heavy hitters like Wolverine, Scott Summers, and Bobby Drake. Her catalog footprint may be compact, but it includes a collector-recognized key issue — a mark of significance that any serious fan will want to take note of.
