User blog:BlueBarracudaMary/Protagonist, Deuteragonist, Tritagonist, Tetartagonist, Pentagonist, What Comes Next?

There are names for numbered protagonists:


 * 1) Main Protagonist
 * 2) Deuteragonist
 * 3) Tritagonist
 * 4) Tetartagonist
 * 5) Pentagonist

I was wondering what would be the best words for protagonists 6, 7, 8, 9, 10. Can you think of any?
