Zerberker

is a Fire-attribute Yo-kai of the Brave tribe. Introduced as Rank S, he was demoted to Rank A with Yo-kai Watch 2.

The Yo-kai Medallium bio reads; "Legend has it that this Yo-kai leveled an entire village with one tantrum. You'll explode with rage if he's around."

As of Yo-kai Watch 2, Zerberker evolves from Hissfit when fused with a Raging Blade.

Appearance
He looks much like Snartle, with a more reddish color scheme.

Personality
He shows almost only rage.

Relationships
Probably none - He's portrayed as quite a rude person.

Abilities and Powers
He can make others explode with rage whenever he's around. He is also generally powerful, having great strength.

Yo-kai Watch
One way to befriend Zerberker is to complete the post-game quest "An Offered Sword", which is given by the old lady visiting the Fortune Hospital in Downtown Springdale during daytime. Obtain a Betrayed Blade by defeating White Reuknights at Hooligan Road in the Yo-kai World, then go to the graveyard behind the Shoten Temple at night, and give Zerberker his lost sword. He will then fight you and join you automatically once you defeat him.

Alternatively, Zerberker appears in the 7th Circle of Infinite Inferno.

Another alternate way to befriend Zerberker is to use the Crank-A-Kai with a Red Coin.

Yo-kai Watch 2
Fuse a Hissfit with a Violence Sword.
