*Eclipse the Darkling is a major antagonist from Archie's Sonic the Hedgehog comics, appearing as the secondary antagonist of the Shadow Fall arc and then the main antagonist of the Total Eclipse arc.
He is a member of the Black Arms race that was created by Black Death to destroy Shadow. When Team Dark - Shadow the Hedgehog, Rouge the Bat, E-123 Omega, and the Spider Troupe arrived at New Black Comet to destroy it with the Mjolnir-Class Tactical Nuclear Warhead, Black Death spied on them with his "seeing eye", and decided to use the Mobian team as "nourishment" for the small army, while Eclipse wanted Shadow eliminated from their plan.
As Shadow began engaging the Black Arms, he ventured further into the New Black Comet, Eclipse stopping him as he wanted him alive if possible. Eclipse then walks by and introduces himself to Shadow.*
