Remus wears a sparkly Stuart era duke outfit in black and green - the shadow color of red. The costume is accented with horror elements such as human teeth and an eyeball. He has a silver quiff in his hair, a curly mustache, and bruise-colored eye makeup. Remus represents a part of Thomas that he did not wish to acknowledge before. In particular, Remus is the embodiment of all disturbing, random and intrusive thoughts that Thomas has ever had and will have, and the desires that he, unlike the kind of desires that his "twin" Roman embodies, does not wish to act on. Remus has also been shown that he embodies Thomas' religious guilt as a result of his Catholic upbringing, which shines through in his spoken lines. 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.
