My neighbor's Excadrill has twice now attempted to kill my Alolan Ninetales (he's shiny, pure chance) and his Kantonian 'sister' (also shiny and pure chance) attacked it in defense. Yugi (Alolan) is very innocent and timid. I was also injured by HIS Pokemon while breaking them apart and he was barking orders at it to attack ME. He's going around telling everyone I told Hailey (Kanto) to attack his Pokemon. He's been trying to get at them since they were kits citing their 'tainted' What do I do?
Call the police. Show them records from the Pokémon center and the hospital. Harboring a Pokémon that attacks in non-battle situations is a felony in most regions.
