Khakkhara

Appearance
He's a little taller than the average Kommo-o. He has a scar under the first scale of his neck, acquired during a devocalization surgery done to him as a Jangmo-o.

Alabaster
While he's currently angry at Alabaster due to an overspending situation, Khakkhara still feels forever indebted for having his life saved by him. They grew close, but while they're separated, he wouldn't be able to hold a grudge if the two met again.

Zollner
He doesn't know much about her, all he knows is that she worked with Alabaster to free him and other pokémon. While he didn't know that when they met personally, he does also feel forever indebted to her for freeing him from certain death.
