Question: Does it immobilize Crota or Oryx? The answer is no; because they're gods and that's clearly going to not do much in the way of slowing them down. And seeing as how Goku is a LITERAL god as of DBZ Battle of Gods/Dragon Ball Super, its not going to touch him either. And it drains Super energy because it's draining a Guardian's Light; depriving them of the ability to use said Light in a powerful way, like manifesting it into a Nova Bomb or Golden Gun
