Stella has beach-blonde hair, biracial skin, black eyebrows, green eyes, brown nose, black shoes and different outfits as mentioned after. In "Hero in Residence", she also wore a long dress and a microphone, along with her guards. In "Giant Consequences", she wore an outfit with purple and gray stripes. In "Jailhouse Block", she has been wearing an outfit that is similar to other associates.
Stella is a rude person who pretends to be nice, and is unfair to the people who work for her. As mentioned by Petra, she's "manipulative" and "pretty fond of herself." She took Petra's sword "Miss Butter" without regretting it. However, Jesse and Petra finds out that she wants to be just like them. Her actions in "Giant Consequences" reveal that she is highly ambitious, believing that the world runs on power. She is also an ungrateful person, choosing to side with Romeo, even though Jesse saved her, if the player chooses to do so, she has been shown to not care for animals, as shown when she threw a puppy in Hero in Residence and hit Lluna in Giant Consequences. However, Stella can be real nice and promised to backup Jesse from Admin Romeo if Jesse was treating her nice and allowed her to join them.
