Sub Arcadia, known as Under Arcadia (アンダー・アルカディア) in Japan, is one of the final stages in Mega Man Zero 3. It is the underground power plant of Neo Arcadia, acting as a central core for all of Neo Arcadia's machinery.
Description[]
Omega and Dr. Weil supposedly fulfilled Project Elpizo from this location, emitting the Dark Elf's influence over all Reploids. When Zero arrived, Weil ordered the Baby Elves to destroy him and retreated. After defeating the Baby Elves, Zero returns to the Resistance Base to learn that Omega is in Weil's Research Laboratory.
If Zero enters Cyberspace in this stage, he can encounter a secret boss fight with the data of Hidden Phantom. Notably, entering Cyberspace in this level will not cause the players rank to have points removed.
