I is a stern, parent-like figure to the lowercase variables in their home. They treat their variables as their students, taking in lowercase variables that have lost their way in life, and despite being strict, they're a very loving parental figure that wants the best for others. They seem to have a desire to appear youthful, despite being over 6000 years old. They tend to replace "me" with "i" when speaking. Adult, they/any.

Q was first presented as very shy and introverted. However, after noticing Soup the Cat, Q became more open-minded. As of now, she's more snarky and irritable, at least when it comes to T, but she's still caring. She's in a romantic relationship with R. Adult. She/they.

R is a relaxed, slow-moving, and quiet variable. On occasion, they appear to have a smug side and get easily annoyed when it comes to T, showing there might be some rivalry between the two. They're generally chill and calm, not wanting to cause conflict or get into trouble. Adult. He/they.

S is an energetic and playful variable. They pertain an excitable and curious personality, seemingly a very happy-go-lucky character. However despite this, they can also be seen easily giving in to peer pressure. Adult. They/them.

T is an egocentric and bold variable. They attempt to take a leadership role amongst R and S, silencing any criticism given to them quickly. They don't appear to be intimidated by the possibility of consequences, often rushing into their decisions and blaming others when things go wrong. They are extremely impulsive. Adult, he/they.
