From Beyond the Unknown #19

In "Return of the Neanderthal Man!", anthropologist Paul Dover stumbles upon the forgotten ruins of a Neanderthal tribe, only to witness their leader, Ogar, return from another dimension after centuries of exile. Triggered by the glow of a crimson comet, the ancient beings have evolved beyond their primal roots, and now Ogar's return threatens to ignite a new age of conquest. With the fate of Earth hanging in the balance, Paul must confront the super-intelligent Neanderthal warrior before his ancient fury reshapes the world.
