The Mutant Chicken Leader is quite "dopey" and did not have much of an intellect because he couldn't be let out in the daylight until the time was right, and when Dr. Animo talked about giving him a name, then said "Impossible", the Mutant Chicken Leader thought he was referring to him but rather he was referring to Ben and his team breaking in.
Powers and Abilities
The Mutant Chicken Leader has sharp claws. He can also fly to escape from enemies. Like the rest of his species, he needs heat to survive.
He can easily be defeated if he is frozen.
