Shardena is a black long-haired female guinea pig. She is the ancestor of Codex, an intelligent guinea pig who created a robot in likeness of himself in Rodents Abroad. Shardena is courageous, skeptical, and antisocial, and likes to only get her way. She likes to stay alone and build things, and most rodents find her stubbornness very annoying. Her nickname for Beirut is 'Belt', because of the orange-ish brown stripe around his waist. She is also very self-conscious about her fur, often complaining if it gets messy or tangled.
