| Synopsis | Superboy meets Yango, a gorilla from Krypton, who speaks Kryptonian and possesses the same powers as Superboy. Yango was sent from Krypton to Earth in a parallel ship by noted Kryptonian anthropologist An-Kal to preserve the endless hours of intensive cybernetic brain-programming to prove his unpopular "genetic alterance" theory. An-Kal seems to have also have believed Jor-El's theory of Krypton exploding, another unpopular theory spouted by an ignored crackpot. Yango metes out justice to poachers and the random warlord and Superboy establishes himself as The Super-Ape's ally. Yango has excavated his own Fortress equivalent. |

| Notes | Lettering credit from reprint in Legion Archives. Story includes short retellings of the Legion origin story from Superboy #147 and the Lightning Lad/Lightning Lass/Lighting Lord origin. In the fight to subdue him, Lightning Lord's hair is turned white, as it had already appeared in the adult Legion stories. There is no feature logo on this story, as the feature title varied in the first back-up stories after the series moved to Superboy from Action Comics. |
