The Many Deaths of Marrissa Picard

Marissa Amber Flores Picard is the star of a series of Legendary Badfics in Trekverse.

Character History
Before adolescence, she was already a commissioned officer (in charge of what the Suethor dubbed "the Children's Crew," and an adept (although childish) negotiator. In one fic, she sharked a Klingon and lived to tell the tale.  In another, she successfully negotiated peace between the planets Sobnia, Bresa, and Troac in the Naklab system.

Character Demises
Agent Alec Troven has killed her six times and counting. The Department of Geographical Aberrations took out the Naklab system with a Sun Crusher.
