"The Black Arms had been making preparations for the invasion as far back as 2'000 years ago, when the race transported several flying temples to the planet were they had remained becoming ancient ruins. (VG: ShtH) During the Black Arms previous, and most recent visit to the planet, Black Doom met and became acquainted with Gerald Robotnik, who at the time was working aboard his Space Colony ARK to find a cure for the illness ailing his granddaughter Maria Robotnik. During this time, Black Doom agreed to aid the professor in his creation of the ultimate lifeform, Shadow the Hedgehog, to help further Gerald's research, as well as to help Black Doom in his goal to find the Chaos Emeralds, the latter giving his own blood to the creature. The partnership later disbanded when the professor realised the threat his new alley posed to the world. For this reason, Gerald planned to have Shadow and his newly built Eclipse Cannon super weapon to destroy the Black Comet upon it's next visit 50 years from then. This plan was initially forgotten after the professor sank into depression and became unhinged upon the death of Maria and his arrest at the hands of G.U.N. (VG: SA2, ShtH)"@en . "Black Arms"@en .
