Billow, a pirate of the Neimoidian species and male gender, engaged in acts of piracy. Poe Dameron managed to seize one of Billow's illicit cargos. Pursuing him to Takodana, Billow faced Dameron in combat, ultimately suffering defeat due to the assistance of BB-8. He was the pilot of a V-wing starfighter.
The character of Billow made his debut in the comic strip "Trouble on Takodana," which was included in the publication LEGO Star Wars 55.
