>>8881886The 86 characters were at least explored pretty well in the UK comic. Since it got started very late into MOTUs lifespan it was always advertising what was new on the shelves and mostly focusing on the 86-88 period. Rio Blast had a proper introduction episode and then a full origin, and Snout Spout got even more.
He had first an introductory episode that fully explored his tragic origin (largely the same as the She-Ra episode but more detailed), then he had another feature story (pictured) where he had to choose between returning to his normal, pre-cyborg self and saving He-Man, and then he was one of the core characters in a few adventures like the memorable Prison Star story. When the comics swapped to doing reprints of the German Ehapa material he became just one in the crowd again though he at least kept appearing.
