UFO Man

The giant hero who has always been fighting in numerous giant extraterrestrial monsters that rampage throughout Japan, until the he accidentally steps on Silk, Vivienne, and Tsubomi. Out of sympathy for the girls (while also blaming the monster for their deaths), he sacrifices much of his power and energy to resurrect the three of them. In doing so, his body shrinks considerably, forcing him to rely on a UFO-like craft to levitate.
