The Chaos Emeralds are mysterious gems of great power, and primarily appear in the Sonic the Hedgehog series of video games, comics and TV shows.
When the seven Chaos Emeralds are gathered, Sonic the Hedgehog can turn into Super Sonic, changing colour from blue to yellow, gaining the ability tofly and of near-indestructability, among other new powers. This transformation can occour to other characters in the series, including Shadow and Silver (both of whom are also hedgehogs).
In the game Sonic Colours this transformation is also accompanied by a repeating jingle.
In the parodies
The only notable time that Chaos Emeralds have ever played a role in the parodies is in FegeleinTheLostTapes' parody Viva La Fegel 2 . It transpires that Fegelein went 'dimension hopping' in search of some antic tools, however, he only found a bunch of emeralds that were 'useless to him', so he gives them to Günsche.
After persuading Hitler to ask him how his day went, Günsche, with the Chaos Emeralds, undergoes a 'super transformation'. Now glowing yellow, Günsche smashes out of Hitler's office with the aforementioned jingle playing in the background. Günsche later repeats the proccess with other unsuspecting people and the loud, reccuring jingle starts to drive Hitler insane, resorting him to shout "To the rant room!" in preperation for another lengthy outburst.
