Blackhole

Blackhole is an Guzzlord owned by Bellinor Nanu, and is a character in Nanu's Revenge and Nanu's Paradise. He is Nanu's seventh known Pokémon, caught in NP and is kept in a Beast Ball.

Description
Blackhole is a large Ultra Beast, but he is 44% smaller than a regular. He is a bipedal creature, mostly black in colour, with bioluminescent blue and yellow markings. He has a massive, cavernous mouth, with two smaller mouths protruding from it. The smaller mouths had teeth and tongues on the insides. His head was small and triangular, with small bioluminescent blue eyes.

Before being captured by Nanu, he was destructive, but it was later learned that Lusamine forced him to do these things, under the threat that she might kill him if he didn't. He greatly calms down, and feels guilty for destroying Alola. He also comforts Gigi, as he is actually a kind and caring Pokémon, despite his large and intimidating size. He is also fluent in the Pokémon language, learning it after living with Lusamine for so long, and is shocked that most of the characters know Pokémon language as well.
