Chaos Emeralds

Chaos Emeralds were a set of seven emeralds containing a high level of power that originated from Sonic's dimension. They came in Blue, Cyan, Green, Yellow, Red, Purple, and White.

After the events of the first Genesis Wave as well as Sally sabotaging the Genesis Wave Generator, the Blue Chaos Emerald somehow ended up transported to the Amazon in Earth 20XX, Mega Man's realm. Flash Man, a Robot Master on patrol in the area, uncovered it. He then brought it back to his master, Dr. Wily, and reported his findings while the latter argued with Ra Moon about his desire to create a Met with a rice cooker function. Wily initially thought it was a sapphire, although Flash Man replied that the spectral analysis on the gem indicated it was a beryl, with Wily commenting he wasn't a geologist anyways. He also tried to have it analyzed due to Ra Moon commenting that it had a high power output. He initially thought it was a new variant of the Energy Elements, although the power output caused the scanner to blind Wily and Flash Man. He later was contacted by Dr. Eggman (who had been tracking down its location since its disappearance), and then formed an alliance. Upon using the Genesis Wave to rewrite reality not only on Mobius, but also in Mega Man's dimension, the two doctors proceeded to locate the remaining Chaos Emeralds. The Roboticized Masters Knuckles Man, Rose Woman, Shadow Man, and Tails Man, alongside Metal Sonic, were later dispatched to Mega Man's dimension to rob the bank of its Chaos Emerald. They met some resistance against Mega Man and Proto Man, although they ultimately escaped due to Metal Sonic's interference. The Roboticized Masters save for Tails Man later returned to the Skull Egg Zone to report the success of their retrieval of the Chaos Emerald while Wily and Eggman watched Sonic the Hedgehog and Mega Man fight each other. Later, Silver Man and Blaze Woman returned with the Green Chaos Emerald. They then used it to power the Genesis Wave Generator in order to become demigods of time and space. Later, Sonic and Mega Man (the latter via the Rush Super Adaptor) then entered into their Super Modes and managed to stop Wily and Eggman, with Mega Man's dimension returning back to normal.
