Tock

"You're the Grimm Reaper. And these are the last sixty seconds of your life."

- Tock to Maria Calavera.

History
While most of her past is unknown, Tock and her group were hired by someone (speculated to be Salem to kill all of the Silver-Eyed Warriors that could pose a threat to the Grimm forces throughout Remnant.

Eventually, Tock and her group happened upon a young Maria Calavera, who used her Silver Eye power to kill a Nevermore, and proceed to attack her. While Maria easily handles the others, she struggles against Tock's speed and swordsmanship. Tock relentlessly attacks her, eventually knocking her down and depleting her Aura. Maria gets back up and fights back, and the two's weapons collide. However, Tock uses her teeth and jaws to bite through Maria's defense and headbutt her, breaking her mask and leaving her vulnerable. With a single swing of her sword, Tock violently cuts out Maria's eyes.

Tock proceeds to mock Maria and dodge her attempts to fight back. As she stands over Maria and prepares to kill her, Maria summons one of her scythe blades to stab Tock in the back. As Tock falls, Maria uses her other blade to decapitate and kill her.
