Mantasphid Queen

The Mantasphid Queen was the monarch of the insectoid Mantasphids and was significantly larger than the rest. It had decided to invade Myarr for the dung from its animals, and they engaged war with the native humans. She is naturally phospheresant. She craved dung and so wanted to keep hold of Myarr. She made a deal with Ulysees Meregrass to deliver weapons, she refused to pay so he abandoned her. She panicked and asked the Tenth Doctor to negotiate a surrender for her. The Doctor did this and took the blame, he escaped from her lair before he could be arrested. (TV: The Infinite Quest)
