Tock

Tock was a character in RWBY that first appeared in "The Grimm Reaper". An assassin, she was an associate of Salem and part of her inner circle.

Tock was a Crocodile Faunus with a shaved head, greyish-green skin, a messy dark greyish-green mohawk and yellow eyes. She wore a dark green collared shirt with a dark brown corset that has a strap attached to a narrow belt around her thigh, black and gray striped trousers and black shoes. In addition, she wore dark brown fingerless gloves and carried a large stopwatch with her.

Her Faunus trait was patchy shady green scales all over her body and face. She had an x-shaped scar on the left side of her head, black polish on her nails and sharp metal teeth with two screws in them.

Tock was cruel, sadistic and brutal. She had no problem using dirty tricks to defeat her opponents. She was also rather arrogant, possibly due to her limited invulnerability. She claimed to be merciful, offering to spare Maria's life if she begged for it. In a dismissive way, she claimed she respected those who fight to the end.

Tock is described as having been proud of herself, especially of her Faunus heritage, to the point of having replaced her original teeth with a set of metallic crocodile teeth to enhance her imagery. Additionally, despite warnings from her master, Salem, Tock never grew to be cautious in regards to using her Semblance before her invulnerability wore off, instead choosing to play with her victims.

Tock's weapons of choice were her Swords. They appeared to be a pair of inner circle golden-hilted cutlass styled swords, with Tock having been shown and skilled enough in swordsmanship to easily fight and keep up with Maria Calavera, an impressive accomplishment considering the latter's own prodigal talents as a fighter. Tock was talented enough to even hold the advantage for the majority of the fight and overpower her.

Tock's Semblance, Invulnerability, gives her the ability to become completely invulnerable for 60 seconds, creating an absolutely invulnerable full body Aura shield that completely shields her from all attacks. Unlike the typical Aura cloaks, Tock's Semblance does not weaken or break while within the set time limit. However, the use of her Semblance causes Tock to shatter all her Aura after the 60 seconds have passed, effectively leaving her completely defenseless and open to being hurt.
