Soundproof, or something with the same effect
Shadow Tag, or something with the same effect
Scary Face or something with the same effect
Information about Breeding to get the desired moves would be helpful, but simply mentioning a Pokemon that can have the fallowing desired effects:
Immunity to Roar
Immunity to wild Pokemon using Run
would be greatly appreciated. Any Pokemon mentioned to me I'll do the required research myself to see how it's done. I just need to know which one it is. The only requirement is it has to be something available in Gen IV HG.
