Tobias Erin "Toby" Rogers, also commonly called Ticci Toby, is an enthusiastic member of Team Operator, as well as a fairly skilled fighter. His main offensive weapons are twin hatchets, but he has also been known to use fire-based weapons.
As a child, he was bullied because he had motor tics (alongside several mental disorders), hence the nickname's origin. After many years, Slenderman began following Toby, who was strangely unaffected by both the Sickness and Sigma Radiation. Eventually, Toby started refusing things, then eventually gave into the voices inside his head, and murdered his father. Brutally. In an attempt to escape, he set his entire neighborhood on fire, but was caught in the flames and had to be rescued by none other than the Tall Man himself.
After some time as a Proxy, Toby started killing in a brutal manner. Nobody really had any idea why, he just did. After a while of doing that, he was approached by Alex, who (after nearly getting cleaved in half) managed to convince Toby that there was something better in store for him if he decided to go with him. Toby went, and saw that his "Father" (Slenderman) was there too.
He also happens to suffer from bipolar disorder.
