Enel
After the Space Pirates were defeated, Macro along with the other Spaceys and the ones on the moon become loyal soldiers to Enel.

History
Sergeant Cosmo was first introduced in mini cover-story of Enel's Great Space Operations. One day Cosmo along with the other spaceys and Dr. Tsukimi were watching the moon and eating snacks when suddenly a huge explosion happened on the moon. The explosion was the result of the Space Pirates destroying Enel's ark Maxim. Professor Tsukimi, shocked, swallowed his dumpling without chewing, resulting in him suffocating to death. After burying the professor, the four spaceys traveled to the moon (each one with a balloon) to take revenge on the one who caused the explosion that resulted in the accidental death of their creator. Upon reaching the moon, they find the same Space Pirates that destroyed Maxim, and despite overwhelming odds, they fought the captain of the Space Pirates. In the end, however, Cosmo along with the other three spaceys were defeated.
