List of Pantheons

Pantheon Guardian
Pantheon Guardian (パンテオン・ガーディアン) is a standard Pantheon with an electric club. In the "Find Hidden Base" mission from the first Mega Man Zero game, where Zero fights against Blizzack Staggroff, they are green and their eyes are used as spotlights to detect intruders. 

Pantheon Hunter
Pantheon Hunter (パンテオン・ハンター) is a standard Pantheon equipped with an arm cannon. It is the simplest, in design and function, of the Pantheons and has its first appearance in Mega Man Zero's introductory sequence. This one fires three shots in a row. 

Pantheon Ace
Pantheon Ace (パンテオン・エース) is a pair of flying Pantheon sub-bosses. They are the first of three bosses Zero must face in the Neo Arcadia Shrine stage, first appearing as statues. They are slightly faster and more lethal versions of the Pantheon Flyers, but only take few hits to kill. The only real danger during the fight is the spiked pit in the center of the room. They are the only kind of Pantheon seen with visors instead of one cycloptic eye.

Pantheon Aqua
Pantheon Aqua (パンテオン・アクア) is an aquatic Pantheon from Mega Man Zero 3 that shoots harpoons that shoots in 8 directions like metal mans metal blades in Mega Man 2  

Modified Pantheon Aqua
Modified Pantheon Aqua (改造パンテオン・アクア) is the sub-boss of Childre Inarabitta's stage, Oceanic Highway Ruins. It's a Pantheon Aqua modified by the Dark Elf when it tries to attack it.

The power it received causes it to morph into a form similar to Elpizo's second form in Mega Man Zero 2 (and shares similarities to Copy X's Seraph form from the first game, fitting due to being a mass-produced copy of X), and may have been driven insane, as it destroyed one of its own kind without reason (though the other Pantheon Aqua being destroyed may have been an accident). It also gained the ability to speak, since it lets out gremlin-like cackles and mutters phrases spoken by Copy X's Seraph form in an extremely high pitch. The Modified Aqua uses its sharp claws to shake the walls of the room, causing chunks of the ceiling to rain down from above; fires a pink, sweeping laser from its eye; shoots five, flaming harpoons in contrast to one normal harpoon; and tries to grab Zero and drain the life force from him. After its defeat, Zero receives the Cyber-elf Kynite.

Pantheon Base
Pantheon Base (パンテオン・ベース) is a green Pantheon from Glacier Le Cactank's stage, Snowy Plains. It uses a flail hammer and rides a hovercraft. Zero can also use its hovercraft after destroying it. Respectively, they look and attack like Glacier Le Cactank, and only appear in the Snowy Plains, implying they might be his own personal Pantheon guards.

Pantheon Bomber
Pantheon Bomber (パンテオン・ボマー) is a Pantheon that throws bombs from the broken windows of Deathtanz Mantisk's stage, the Old Residential Area. They will go back hidding behind the windows if their target is not around.

Pantheon Core
Pantheon Core (パンテオン・コア) is the boss of the "Destroy Train" mission in Mega Man Zero. It's the core of the train, located in the engine chamber. It attacks with a flamethrower and tries to smash Zero into hidden spikes on the ceiling by lifting the floor. If the player has a high rank, it will also use Brain Pressure. The Cyber-elf Totten is gained from its defeat.

Nickname: 頭脳特急 (Zunou Tokkyuu, Brain Super Express)

EX Skill: Brain Pressure (ブレインプレッシャー)- The Pantheon Core will slowly move forward to smash Zero while it's attacking with the flamethrower and 1 or 2 of the floor segments up.

Pantheon Fist
Pantheon Fist (パンテオン・フィスト) is a Pantheon with large fists from Mega Man Zero 3. Their punch can push Zero off an edge. It is possibly an upgrade of the Pantheon Warrior. Their fists have thrusters to make their punch stronger and faster (since there might be a clue that the fists are heavy due to its' speed on moving towards zero).

Pantheon Flyer
Pantheon Flyer (パンテオン・フライヤー), is a flying Pantheon equipped with an arm cannon like the Pantheon Hunter. It can fly to the background to evade Zero's attacks.

Pantheon Hammer
Pantheon Hammer (パンテオン・ハンマー) is an armored Pantheon equipped with a flail hammer and a shield. The shield can be removed with the Chain Rod. Most only throw their flails at Zero, but some, if given enough space, will actually charge to attack him. Their attack behavior resembles the Hoganmer's from Mega Man X. 

Pantheon Hopper
Pantheon Hopper (パンテオン・ホッパー) is a Pantheon from Mega Man Zero 2. They crawl towards Zero and leap to attack when close. 

Pantheon Launcher
Pantheon Launcher (パンテオン・ランチャー) is a Pantheon from Mega Man Zero 2. It has a giant cannon that shoots several large energy spheres in a row. 

Pantheon Warrior
Pantheon Warrior (パンテオン・ウォーリア) is a Pantheon from Mega Man Zero with a large fist. It uses the thick armor on its fist to block shots, and charges after Zero on sight.

Pantheon Zombie
Pantheon Zombie (パンテオン・ゾンビ) are dead Pantheons summoned by Anubis Necromancess. They can't inflict too much damage, but they can trap Zero long enough for Anubis to attack him. 

Pantheon Corpse
Pantheon Corpse (パンテオン・コープス) is a broken Pantheon found in Fenri Lunaedge's stage, the Hibernation Chamber. Scrap elves can revive them. It acts similar to the Pantheon Zombie and the Pantheon Guardian. 

Unused Pantheons
In the book, Mega Man Zero Official Complete Works, there are sketches of three Pantheons that were not used in games:
