The Saturn Rebels are a gang of troublemakers that killed a lot of people. Many have tried to kill any member of the gang, but they have all failed.
Pluto is the one Saturn Rebels member that is considered defeat, since he has been missing for years, so much so that he was presumed dead.
Their master, Saturn, never reveal his real face, and all we have is this picture of 2020, taken by a hunter who lived in the forest during the pandemic.
We are not sure if it is really Saturn, but, considearting that the members of the Saturn Rebels are generally orange-lined, it maybe could be him.
