Deminica

Deminica was a Mary Sue slain by Agents Jay and Acacia. She appeared in a Lord of the Rings badfic notable for being a "Code 18"--including nine Tenth Walker Sues, the highest recorded number.

Character history
Deminica was the lead Sue of the Sisterhood, a group of nine Sues that joined the Fellowship after pointing out that "your hobbits are weak compared to ours" and turned Boromir into a bigot who didn't want any "girls" in the Fellowship. She was an elf who had "yellowish/greenish eyes" and ears "tipped with gold". She may or may not have also been an Istari.

The Sisterhood was composed of "One human, one dwarf, two hobbits which don't come from the Shire, and five elves." In Acacia's opinion, they were "a troupe of fluffy shallow bitches with no distinct personalities, the combined IQ of a raisin, and worse grammar than Gollum," and Boromir rightly wondered whether they could do anything other than look pretty.

The Sisterhood was rejected from the Fellowship at Rivendell, but accepted after they beat up various members of the Fellowship at Lorien.

Character demise
Deminica attempted to defend herself by creating a magic bubble for arrows to bounce off, but Jay (in Istari disguise at the time) used her own staff to break Deminica's shield, and Acacia shot her with an arrow.

The body was thrown into the middle of the ocean as an offering to Ulmo.

Charges
Deminica was charged with "bad grammar, interfering with the characters of the entire Fellowship of the Ring, spending way too many sentence-long paragraphs on your clothes and not one on the Golden Wood, calling it Loth Lorien, and being a Mary Sue, also keeping Gandalf alive, having metal on your ears in a way that defies all logic, and [acting] psychic."
