Gordon is a red, bat-winged creature who faithfully accompanies the demon child Ackman on soul-collecting missions. His primary task involves gathering the souls of humans killed by Ackman into jars for sale to the Dark Lord or Great Demon King, forming a central economic aspect of their activities. While consistently depicted with red coloration and bat-like wings, visual portrayals show variations in exact hue and wing size across different sources.

He appears in all official adaptations of the series: the original manga, the 15-minute animated film, and multiple Super Famicom and Game Boy video games. Within these games, Gordon participates in narrative interactions, engaging in playful banter with both Ackman and their rival Tenshi-kun, an element noted as contributing to the adaptations' charm.

Available materials document no significant background story, origin details, or character development for Gordon. His portrayal remains focused solely on his operational role in soul collection and his dynamic with Ackman throughout all media appearances.
