Ogralus

is a Water-attributed Boss Yo-kai, and the second boss of Terror Time, a sub-dimension that can overlay over the real world with little warning beyond a countdown, where he and his Oni brethren inhabits. He is one of the Oni who can appear in Terror Time if his brother, Gargaros, is defeated enough times. If Ogralus is defeated enough times, the even more powerful Orcanos will begin to appear.

In Yo-kai Watch 2, Ogralus is now able to be befriended. Like his red-hued brother, his befriendable Yo-kai form retains his elemental attribute and is a S-ranked Yo-kai of the Tough tribe.

Appearance
Ogralus closely resembles his brother Gargaros, being a towering figure with clawed limbs and huge teeth. Distinguishing him from the other oni are his blue skin, red ponytail, and the two straight horns poking out of his head. He wears a grass skirt and carries a massive, spiked club.

Personality
Ogralus is even more ruthless than his brother, often more willing to teleport himself to the player's location, even if the player technically has not been spotted. He will chase down the player with ruthless efficiency.

Relationships
Ogralus appears if his brother, Gargaros, is defeated multiple times, representing an increase in the difficulty of Terror Time.

Abilities and Powers
Unlike Gargaros and Orcanos, Ogralus prefers to fight using his water Elemental Attack, which can prove problematic as many of the game's mascot Yo-kai, such as Jibanyan, Komasan, and Kyubi, are weak to water. He still boasts powerful physical attacks, too.

Origin
See Gargaros.
