[Thor: Ragnarok] what would the nerve disturbance device do to beings such as Korg and Groot?

And as a bonus, what would it do to Hela?

Obedience discs are rather powerful. Since not-Korg is already was a gladiator in there, it's safe to assume that they work on him, even though he's made of rocks. And if they work on rocks, they would work on trees too.

In original Planet Hulk obedience discs were strong enough to hold Silver Surfer for a while.

EDIT: and since Hela is stupid powerful only from her connection to Asgard, it's likely they'll work on her as well, as long as she's on not-Sakar.
