Honestly I think using someone elses finisher, like the move and name;.. is a bit disrespectful. I mean by all means, use a finisher that someone else has.. just call it something different that works for your character. I mean, Ally's moves have been like that since 1999. I wouldn't walk over and steal say Nova's moves or something like that, out of my respect for him or anyone else as a writer. To use someone elses move's to me is like stealing their work.
