History
After the New Black Comet's destruction, Eclipse the Darkling and the eggs of the Dark Arms had escaped the explosion and were heading straight to the Red Mountain Zone. After crash landing, Eclipse realized all but four eggs of the Dark Arms were crushed from the attempted-landing. He had then trained and raised the remaining four Dark Arms–Blurk, Cyzer, Cregal, and Rhygenta, feeding them with Angel Island natural berries. Eventually, Team Dark–Shadow the Hedgehog, Rouge the Bat, and E-123 Omega–traveled to Angel Island to find and destroy Eclipse. With the help of Knuckles the Echidna, Rouge, Omega, and the Rad Red himself traveled to Red Mountain Zone to search for Eclipse. Eclipse, however, eavesdrop on the three heroes, and after hearing Shadow being name dropped, he immediately went to the Shrine Isle to get his revenge on Shadow.
