Please at least include a none of the above option.
I'm a grown man with a fantastic car, lets at least see if we can have a name I'm not embarrassed to reference.
Of the 5 listed, you have 1 comic book reference, 2 gangster references, 1 uses the word jihad which is considered offensive in many circles for a variety of reasons, and a Rugby reference which just about everyone is going to be confused about. Of the ones you list the comic book one is the least objectionable, but at the same time, people will expect a dark knight group to be about something else.
I suppose it's possible I'm alone in this. Maybe I'm just showing my age and what you really want is a tongue in cheek group that specifically targets younger kids. If so my apologies.
