Spike

Spike is a bird from the Angry Birds episode, Bully Birdy. Spike was known back in Squawksburg as a bully who hurt, stole from other, and was an overall bully. When he moved to the Angry Birds' field, he decided to bully the other birds, mostly Bubbles, the Blues, and Stella.

His special ability to blow spikes around his body in defense, hence his name.
