Eggman

thumb|218px|left|Using cheat codes and cheating devices, the Eggman can actually appear exclusively in the Advance version of the game. It was a dummified monster as well.

As a secret summon, the Eggman is exclusive to the Japanese version of Final Fantasy V, as well as a replacement of a monster for some strange reason. It is originally a guest character from the Hanjuku Hero series. However, the monster itself is extremely weak, even weaker than Goblins.

Also, note the fact that the name is also N/A, because the monster itself is nameless as well. Watch the featured video for specific information.
