The Heart's Bounty Logo


The Heart's Bounty is an Yaoi anime spin-off of the series Sonic Underground.  It was created by the studio BONES and is dubbed by both Funimation and some former 4kids voice-actors. The series is focused on the lives of the original villains in the original show. The Heart's Bounty is divided into two parts consisting of six "chapters" each. The first part focues on Sleet and Dingo becoming a couple and the second part focuses on the return of Naugus. 


Sleet and Dingo, though they worked together, could very rarely stand each other. That is, until one mission began the sequence that would forever change how they felt about one another.
