Not to be confused with the Ruby Birthstone.
They seem to look strong and muscular, with their eyebrow bone pointing down as if angry. With long pointed ears for a Rhinoceros avatar and two sharp-pointed horns, the front horn seems to look like a replacement since it has a rope hanging around it; although it could just be decoration. They have four rectangular flecks on their cheek-bone.
- The word Ruby comes from the Latin origin meaning 'red'; their name could also be after the Gemstone Ruby.
- The only references to them in the game are the Ruby Statue and the Bronze Ruby Statue.
