Bug is the final boss of Parodius, and one of the few Gradius final bosses in the series who attacks.
Aside from the pitiful defense offered by Jikkyō's final boss, it IS the only final boss in the Parodius series who attacks.
He inhabits The Fortress Of Bug, a base amongst the flotsam of numerous asteroids.
Earthlings of the past were filled with the dreams and hopes, people trusted each other, paid respect to each other, harmonized, made company, once upon a time it was a fantastic planet. In AD 1988, middle of the school entry exam season, people were losing their dreams by global scale. Bug devoured and corroded the dreams and hopes that Tako programmed and gave to the people. And, his appearance was always sudden. Bug is definitely behind this. Bug was approaching the Earth! 
- Japanese people believe tapir eats human dreams. The animal has the nickname "baku", which is almost homonym to bug, hence the boss' name.
