Ruby is often the voice of wisdom among the young dinosaurs, able to explain matters the others do not understand. She has a calm demeanor and shows kindness and empathy to others. A strange habit of hers is to sometimes immediately repeat herself in a "backwards" way. For instance, she might say as a greeting: "Hello my friends; my friends hello!" She may be considered the "opposite" of Chomper, being female, calm, and more relaxed than him (she preferred to relax in warm mud over playing a sport with him in one episode). She is also older and smarter due to more experience in life.
