John Welthork (ジョーン・ウェルソーク, Jōn Uerusōku) an Australian member of the Bugs II mission who dreams of one day taking his grandmother on an overseas vacation. His favourite food is fried silk moth. He dislikes banks.
Prior to joining the Bugs II mission, John lived on a farm with his Grandmother, raising sheep as a living. However, an epidemic wiped out their entire flock, forcing John to join the Bugs II program in order to provide for his grandmother. He is first seen on the spaceship Bugs #2, laughing at Shokichi's jokes. Later when a cockroach broke in the spaceship, following captain's order he was able to escape with the rest of the crew, eventually stumbling across the Bugs I ship.
When Thien suggested they examine the ship to see if it still functioned, John remained outside with Redon in order to keep watch. He and Redon were killed by Roaches that had stolen human firearms from the ship and had been lurking under it to ambush anyone that came near.
