Dark MegaGem

In book 6, MegaGem hires Dark MegaGem as captain. MegaGem becomes 2nd in command, meaning Okasis is now down into 3rd place. 8m8 is so proud of Dark MegaGem (because he saves his life in book 6) and MegaGem because he hired Dark MegaGem. Surely nobody said some utterly fearless member would come?
