Legion of Super-Heroes #3

The cover by Curt Swan and George Klein lays out a genuinely tense three-way dilemma: the massive yellow robot Computo the Conqueror has ensnared Superboy with mechanical tentacles, while a bound Triplicate Girl is shown being destroyed in the upper right, and a restrained Lightning Lad struggles at lower right — leaving Superboy agonizing over whether to fight or surrender. Billed as "the electronic enemy programmed to wipe out Super-Heroes," Computo makes for a formidable 1973 villain whose hostage strategy gives this issue an urgency that leaps right off the cover. Jerry Siegel's script and Swan's crisp, dynamic art make this a satisfying chapter in the Legion's ongoing adventures.
