Armed Phenomenon

The Armed Phenomenon (アームドフェノメノン) is a transformation in the Mega Man Zero series that allows the Four Guardians to increases their strength. The transformation is reversable, and no known danger has been identified from its use. It usually has an animal motif, and is always completely inhuman and mechanical looking.

Harpuia
After being possessed by the Baby Elves, Sage Harpuia unwillingly absorbs their power and takes on the form of a massive bird-like aircraft. Like regular Harpuia, his Armed Phenomenon form has terraforming capabilities, which gives it the ability to emit electricity and create strong winds. It also has on-board missiles, and often tries head-on attacks as well.



Leviathan
Fairy Leviathan takes on the form of a manta ray submarine. She is much more aggressive, despite having lost much evasiveness due to the increase in size that this form gives her.

In this form, her attack patterns change completely, she can now launch two ice dragons, and they can either chase Zero, or lock him into an ice box that she will later break.

Also, in this form, she can launch ice beams from her forehead that will become ice blocks, and later float away, and shoot ice from her forehead, that will ricochet against the ground.

She can also launch mini torpedoes that follow her through the room and later have a pattern of their own.



Fefnir
Fighting Fefnir takes on the form of a dragon tank. He uses its large size to his advantage, slowly and steadily forcing Zero to keep moving through a hall during his battle in his Armed Phenomenon form. He uses his four cannons to keep Zero on his toes.



Phantom
Hidden Phantom becomes a large bat-like creature. His is the only Armed Phenomenon that is not required to fight in the second Mega Man Zero game, due to his death in the first game.

Similar Phenomena
Besides the Armed Phenomenon, there are also unnamed transformations similar to them.

Copy X
Copy X, the former leader of Neo Arcadia, takes a seraph-like appearance in his second form in Mega Man Zero. Most of his attacks in this game are also given an angelic theme to them, such as his imprisoning halos.

Elpizo
When Elpizo finally released the Dark Elf by destroying the Original X's body, he fused with her and became a more powerful version of himself that looks like a knight. When he was defeated by Zero, he then unleashed the true power of the Dark Elf upon himself, merging with her and taking the form of a dark winged monster. This form bears a striking resemblance in appearance to that of the Dark Elf herself, and in this form, the Baby Elves assist their mother and Elpizo in combat.

Modified Pantheon Aqua
During Childre Inarabitta's stage in Mega Man Zero 3, a Pantheon Aqua is modified by the Dark Elf in an attempt to halt Zero's progress through the sunken city area as she continues her escape. Despite its increased power, it is still only a Pantheon, and is easily dispatched by Zero.

Omega
Omega's second form is a giant Reploid which appearance appears to be a combination of X, Zero, and the Dark Elf.
