Superman Adventures #39

Both Superman and Supergirl find themselves bound by writhing mechanical tentacles on this striking January 2000 cover, their attention fixed on a mysterious silhouetted figure crackling with eerie yellow energy. The tagline "A Ghost from Supergirl's Past!" hints at something deeply personal for the Girl of Steel, giving this animated-style adventure an unusually charged emotional undertone. With clean, expressive linework by cover artists Bret Blevins and Terry Austin, this issue from Evan Dorkin and Sarah Dyer's creative run looks like a compelling blend of sci-fi threat and human drama.
