Remus Sanders

Much like Roman, Remus is prone to reckless words and behavior. He himself says that there is no rhyme or reason to what [he] do[es]; [he] just do[es]! He craves attention, and being ignored or (figuratively) dressed down drives him to act even more chaotically.

Overall, Remus is a proudly demented character. His first appearance is defined largely by making the other sides and Thomas uncomfortable by pulling the topic of conversation to obscene subjects such as brutal violence and/or sexual acts.

He's also by far the most physically violent side: while Virgil threatens and intimidates, and Janus employs emotional manipulation, Remus knocks Roman unconscious with a morningstar in his debut, and later assaults Logan with a shuriken and his own teeth. He has no qualms against physically attacking people to get his way, or just because [he's] unpredictable like that.

Somewhat paradoxically, Remus seems deeply offended when Thomas calls him "scary". This suggests that Remus' main desire is for Thomas to implement his brand of creativity, and antagonizing the other sides is an (appreciated) side effect. Or because, as Logan says, the Duke only has power over [Thomas] because Virgil and Patton believe that he does.

In contrast to Janus, who lies almost constantly, Remus is honest to the extreme, going so far as revealing his name the same episode he first appears. This is because he represents pure, unfiltered thought, including the harsh truth.

Remus' speech is peppered with religious references such as Cain and Abel, the tree of knowledge, and even says that [he] was the unloved brother from the Genesis. This is because part of him stems from Thomas' Catholic upbringing and religious guilt.

One of Remus' hobbies is eating deodorant. You can see him doing this multiple times in Dealing with INTRUSIVE THOUGHTS.
