What do YOU think would make a good Nocturne Ultimate Skin?

Topic.

I think a Nocturne ultimate skin needs to be created in S7.

This is a thread to post your ideas on what YOU think would make a great Nocturne ultimate skin (3250).

You dont need to have pictures or a long typed out concept. Just pitch some ideas and if I can I will try to build on them and possibly do some artwork on them.
