Brauggi

Brauggi was an ice construct summoned by Ice King during the events of the unproduced episode "Jake-Less". When Ice King found out that Jake had lost his powers, he summoned Brauggi to attack him and Finn while they were weak. Brauggi was eventually destroyed when Jake, despite the loss of his powers, climbed in through his ear and punched his brain until he collapsed into a pile of slush.

Appearance
According to the outline for the episode, Brauggi is three stories tall and wields a fallen tree like a giant club. He is made out of ice, and shatters into slush following his defeat.
