- Gallon (ガロン Garon )
- The leader of one of Ken-Oh's Invasion Squads (拳王侵攻隊 Ken'ō Shinkōtai ) which occupies Mamiya's village after the destruction of Cassandra. He fights by using a fire-breathing style (similar to parlor tricks) named Katōjutsu (火闘術, "Fire Combat Skills") which involves spitting fire after consuming a whole can drum of petrol. Gallon forces the villagers to be loyal followers of Raoh or else be burned alive on a steel platform. Shortly after, he was killed by Rei when his stomach was sliced open and the petrol leaked onto open flames, causing him to combust.
- His name was first given in the Ten no Haoh manga and mentioned again in the second Rei Gaiden one-shot.
- His fighting style is called Ryuto Kaen Jutsu (竜吐火焔術) in the TV series.
- He may be based on Prince Vultan a well-known birdman from the Flash Gordon franchise.
