Doctor Barus was a Ledosian surveyor who lived during the late 24th century. In 2378, when the energy barrier around the indigenous Ventu on Ledos was released by Seven of Nine of the starship USS Voyager, Barus lead the surveying team to civilize the Ventu and make the best of their land. After he and his team were transported from the planet by Tom Paris aboard the Delta Flyer II, Paris destroyed the shuttle deflector dish that was keeping the barrier open. (VOY: "Natural Law") Barus was played by Ivar Brogger. His costume was sold off on the It's A Wrap! sale and auction on eBay. [1]
