Ogralus in Yo-kai Watch 2

By crossing crosswalks correctly by using the buttons enough times, an unknown voice will ask if you would like to fight him. Accept and Ogralus will fight you. He also appears as a boss in the Irate Eight boss rush in Springdale Sports Club which is unlocked after beating Kat Kraydel.

Ogralus can no longer be fought in Terror Time as the oni bat the player away when approached. He however can be killed with items and will drop a large Oni Orb.

In order to battle and befriend him, you will need a key from Mr. E outside of the old house in San Fantastico and link to a copy of Fleshy Souls with Psychic Specters. You will eventually encounter Toadal Dude by a door. If you enter, you will appear in a grayscale version of Fox Shrine Road. Go to the shrine to challenge Ogralus to a fight. Because he is a boss, he does not accept food and can only have a raised befriend chance with the popularity Skill. After battle, he will not walk up to you like regular Yo-kai but instead change his dialogue and give you his medal. If the player hasn’t befriended him, they can repeat the process once a day until his dialogue has changed, or reset if you saved outside of the Highway and keep going until you befriend him. Like other Psychic Specters Yo-kai, he can't be used in Psychic Blasters.
