Agent X19

Agent X19 was a spy in the employ of Doctor Ivo Robotnik who was sent to the Special Zone to determine whether the Special Zone was ripe for an invasion by Robotnik's forces.

History
Agent X19 was sent to the Special Zone to investigate the possibility of an invasion. While in New Tek City on Planet Meridian, she was attacked by the robber known as Mister Shifter, who pulled a gun on her and attempted to shoot her. However, she was saved by Sonic the Hedgehog, who snatched the bullet out of thin air and defeated Shifter in a fight. During the battle, X19 managed to slip away and teleport back to Citadel Robotnik on Mobius, where she informed Robotnik that the Special Zone forces were too strong for an invasion, and that Sonic was trapped in the Special Zone.

Characteristics
Agent X19 is a red-haired girl who wears a golden loop earring in her left ear. She has peach fur, pink nose and lips, and blue eyes. During her visit to New Tek City, she wore a grey coat with yellow trim, and yellow mittens and shoes with white trim.

Agent X19 is not one of Robotnik's usual cringing servants (like his loyal chief scientist, Grimer), and Robotnik clearly respects her.
