I'm not entirely sure what 'the nothing wolf name neverending story' specifically refers to. It could potentially be a very unique or made - up concept. Maybe 'the nothing' is some sort of abstract idea, the 'wolf' is a character or symbol, and 'name neverending story' could imply a story that has an infinite or unending nature in relation to a name.
The name of the wolf in the neverending story is Gmork. This wolf is not just a simple animal in the story. It has a significant role in the plot. It is like a symbol of the dark forces that are trying to destroy the magical world of Fantasia. The character of Gmork makes the story more exciting and full of tension as the heroes have to face this dangerous adversary.
