Robus is the youngest son of Megan and is part of the guerilla army family on Antilla. Robus is treated like a hardened soldier by older brother Kyle, but is treated with compassion and educated by older sister Miri.
He is instrumental in planting explosives in the depot to throw off the Cylons from Starbuck and Miri's attempt to rescue Robus' father.
Robus stays behind on Antilla along with the rest of his family (TOS: "The Young Lords").
