Spunt those rebels!

The Suns of the Song (aka Suns of the One Song) are rebels whose goal is to break up Omni, the governing body that oversees the omniverse. 

The rebels have claimed responsibility for the Kappa Kidnapping in which half of the residents of the Omni academy (including students and stipes) were abducted while on a field trip in the Kappa Dimension. Intelligence suggests all of those kidnapped are safe and alive, currently stranded in Oblivion.

The standard disguise of the rebels is a shaggy orange cloak and golden face mask depicting the sun.
