From Warren Ellis' Doktor Sleepless comic book series, the Doktor and Nurse Igor plus information about the story's biopunk setting and how stuff might work. This profile was done part-way through the series.
Our old Tony Stark benchmarking notes, though they were our only Tony Stark article for about 20 years, which I'll admit is depressing. We keep them around since it's gonna take a long long while for our chronological Stark writeups to reach the 1990s.
This is classic Thor/Avengers baddie the Enchantress as she was portrayed during the 1960s. A high-level villain with powerful magic, great resources, mighty servants, superior manipulative abilities, etc.
