“Earth's Sister Planet!”

In "Earth's Sister Planet!", Superman faces a dire threat from the ruler of a long-lost world once nestled in our solar system—now home to sentient, dominant dinosaurs. With the planet's heir secretly working to protect humanity, Superman must navigate a clash of civilizations while uncovering the truth behind the ancient world's return. Written by William Woolfolk and brought to life by Kurt Schaffenberger’s dynamic art, with colors by Gene D'Angelo and letters by Milt Snapinn, this 1986 classic features a striking cover by Eduardo Barreto.
