Lord of the Dark Night descended, plunging the entire scene into a mass of dark fog; this is its direct release of the field effect "Nightmare", with an aura and oppressive feeling cranked to the max!
The Lord of the Dark Night is a mythical beast that controls dreams, and its capture method is extremely difficult—it only has a chance to trigger the mythical beast dungeon at a fixed time late at night.
"Ahhh, a mythical beast in the second round!"
"This must be Joker's strongest mythical beast!"
As a very rare Dark-type Paru, the Lord of the Dark Night might have a species value as high as 690, ranking among the top tier deities. However, its HP is lower than a normal Paru's, with all the extra points invested into speed and damage.
Fortunately, the field effect "Nightmare" greatly enhances its evasion rate and also significantly lowers the opponent's attack accuracy, which nearly makes Joker's Lord of the Dark Night invincible.
