Arco Blathereen

Don Arco was an obese Raxacoricofallapatorian, and the patriarch of the Blathereen Family in the 26th century. After he hid in a toxic dump after being hunted by the Authorities, Don Arco could only breathe in poisonous gas.

Don Arco was behind the plan to turn the Justicia system into a massive flame-thrower, to burn other planets and sell the remains as fuel.

He was foiled, and killed by his relative Ermenshrew Blathereen for giving into the Doctor's demands so easily.

After the Blathereen were defeated the last survivour requested that Don Arco's body be cremated, however the Blathereen leapt into the flames and vanished along with Don Arco's body. It was later revealed that Don Arcos body was used by Ecktosca Fel-Fotch Heppen-Bar Slitheen to hide and with the his Aunt Callis Fel-Fotch Heppen-Bar Slitheen (who was in the body of the Blathereen survivour) escaped the funeral pyre by teleport.
