A nerdy chicken who appears to be scared of any threats and has a huge crush on Yin; but, because she never returned any of his feelings, Coop joined the Night Master in exchange for the promise to have Yin when the world was taken over. He is a minor villain and he is seen with some of the other villains in the Yin Yang Yo! intro in Season 1. Coop gave the impression of incompetence, but in reality, he had powers and abilities rivaling Yin and Yang's; in the end, however, Coop couldn't bring himself to go through with the Night Master's plans and held him in place so Yin and Yang could destroy him. However, like the Night Master, Coop disappeared as well, but returns in the The Pecking Order, stripped of his Night Master energy that spread across the world, possessing all who ingest it until Coop absorbs a large amount of controlled evil, enough to make him a Night Master.

The New Coop

He has the ability to create a glowing orange-yellow, bird shaped battle aura, which he dubs the "Shadow Chicken". While using it, he is powerful enough to defeat even Master Yo. In "Gone-A-Fowl" he starts to lose control of his evil, causing him to become a buff, shades wearing, bad boy version of himself whenever he gets mad, reverting back to his dorky self when made happy. In this form, he gains the ability to infect others with his evil, causing them to become powered up evil versions of themselves, which he first demonstrates on a squirrel (John M. Wellnuts), then some people who were mocking him, and finally: Yin! At first, he only changes when he is enraged, but eventually chooses to stay that way because Yin only likes him when he's a bad boy. He turns Yin evil because she'll only date him evil when she's evil; however, after Yin is returned to being good, she convinces him to get a hold of himself and he changes back, yet scenes afterwards suggest that this isn't the last of Coop's evil side. As of the episode "Shadowcluck", Coop can now use his aura to fight evil instead of serving it, and he is now dating Yin. He also likes corn a lot, which he refers to as "Nummy yummy Corn" and eats it in the same manner as a real chicken. His mother is a publicist. Coop is currently a Woo Foo Knight in a Little Less Training.
