Don't be a copycat. It is very bad to copy or borrow from an established identity. Stay clear of legendary names.
Creativity is a spark of genius.
Over-creativity can cause fire and damage. Don't get too creative. Do not twist, bend, stretch, exaggerate, corrupt or modify alpha-structures to their extremes in naming. It may result in difficult,confusing, unpronounceable and only silly names. Do not short-change.
