Ernie

Ernie was a member of Organization Sesame Street XIII. He wielded lightning and used it to electrocute people that he didn't like. He also had sharp knives for stabbing people.

History
Ernie was assigned to Castle Honeydew along with four other members, including his partner Bert.

Despite being slain by Sora, Ernie later returned as part of the Barney Gang, which ironically enough also included 13 members.

He fought Sora along with Bert and Cookie Monster.
