|~ Cyber Peacock to Zero.|
Cyber Peacock, is one of the eight Mavericks who appeared in Mega Man X4. Once an AI used to protect the network from any and all hackers, he was changed by Sigma into being a hacker himself. He only exists as a Maverick to test X and Zero's strength, much like Split Mushroom. In the end, he too dies.
Peacock proves to be a tough boss, as he teleports around and appears only to deliver an attack, after which he vanishes again. When he appears, he will either do a jumping maneuver or expand his tail's mechanical feathers, which cover a considerable area around him. After taking enough damage, he appears on the center of the arena, after which he puts a target on the player and starts shooting homing missiles which are very tough to avoid. His weakness in the Soul Body and the Ryuuenjin.
