I have an old Harley shovelhead bike and wanting to do a halloween theme this winter and am looking to get a personalized license plate for the bike.

You can only use 6 letters in my state for bikes so I am asking for your help on picking a plate name.

Some I am considering that are available:

undead
evil 1
horror
skull
Freak
Creep
Mental
Cursed
BadEgg
IMEVIL

I was hoping to land Reaper and do a grim reaper theme but no luck she is taken.
