The armored rat was a large, hard-plated rodent native to the lower and bedrock levels of Coruscant. It had a strong, painful bite and was known to bite unwary beings without provocation. There was a soft spot at the back of its neck, just between the head and body carapace. It may have been related to the borrat.
