The Four Guardians, known as the Four Heavenly Kings (四天王 Shitennou) in Japan, is a group of four powerful Reploids that were created from the DNA of the original Mega Man X to serve and protect Neo Arcadia against evil forces.
The group consists of Sage Harpuia, Fairy Leviathan, Fighting Fefnir, and Hidden Phantom. They are the most elite soldiers, military commanders of Neo Arcadia, ruling the city as a council alongside the Eight Gentle Judges and Copy X. Each of them wields one of the Ten Shining Weapons and has an Armed Phenomenon form. They were gathered from various areas to counter the Resistance efforts.
|Sage Harpuia: Leader of the four, commander of the Strong Air Battalion, the air force.|
|Fairy Leviathan: Aquatic commander of the Deep Sea Squadron, the navy.|
|Fighting Fefnir: Valiant commander of the ground troops, the Scorched Earth Squadron.|
|Hidden Phantom: Commander of the Cutting Shadow Squadron, the intelligence unit.|
The original purpose of the Four Guardians was to restore the lands damaged by the war. To perform their duty, they scattered across the world and acted as the controls of a weather-controlling station called Weather Orbit. Harpuia and Leviathan also partnered to help humans repopulate habitable areas, while Fefnir led Operation Scorched Earth. However, when the Resistance was created, the Four Guardians gathered with a common goal: to protect Neo Arcadia and eliminate the opposition, even though their weapons were not made for that purpose. To that end, they took command of Neo Arcadia's armies.
Neo Arcadia era
While the Four Guardians initially have the edge over the Resistance, the situation changes with the awakening of Zero, who, joining the Resistance, singlehandedly defeats the Four Guardians and stops each attempt to destroy his allies. When Zero infiltrates Neo Arcadia itself, the Four Guardians fight the legendary Reploid once again to stop him from reaching Copy X. Despite their best efforts, as well as Phantom's sacrifice, they are ultimately unsuccessful in preventing the fall of Copy X at Zero's hands. Harpuia is then elected as Copy X's substitute while covering up his master's demise.
One year later, Harpuia unexpectedly saves a broken down Zero by taking him back to the Resistance, but he still joins his fellow Guardians to protect Neo Arcadia from Elpizo's Operation Righteous Strike. In retaliation, Harpuia sends a bombardment aircraft to destroy the Resistance, but the attack is stopped by Zero. When Elpizo runs amok with the Baby Elves to release the Dark Elf, the three guardians are eluded by the deranged Reploid and influenced by the Baby Elves to fight Zero, who was in pursuit. Although they are defeated by Zero, Elpizo successfully destroys X's body, releasing the Dark Elf before he is finally stopped.
Two months later, the guardians join forces once again to destroy Omega, who recently returned from exile. However, Fefnir and Leviathan are badly damaged and forced to retreat as Zero joins the fight. Harpuia appears soon afterwards to attack Omega, but the fight is interrupted by Dr. Weil and a revived Copy X, who prioritizes the capture of the Dark Elf. Although Harpuia objects to the return of Dr. Weil and Omega to Neo Arcadia due to their role in the Elf Wars, Copy X justifies that their banishment did not follow official channels. However, the Four Guardians' repeated failures and Harpuia's questioning eventually irritate Copy X, who decides to disband the Four Guardians and transfer their authority to Dr. Weil. When Neo Arcadia's hunt for the Dark Elf results in the destruction of a residential district, an enraged Harpuia attacks Omega, who merges with the Dark Elf and critically damages the ex-guardian. Although Harpuia is saved by Zero and repaired by the Resistance, he decides to continue protecting the humans by himself.
As Zero fights Copy X and Dr. Weil's forces, the Four Guardians are reunited by the original X; after contacting Phantom's soul in Cyberspace, the two approach Fefnir and Leviathan, who remain in critical condition since they were denied repairs after the fight with Omega. Although Phantom stays behind to meet Zero in Sub Arcadia, Fefnir and Leviathan move on to join Harpuia despite their condition, and the three eventually help Zero by attacking Omega together in the final battle. It is unknown what happens to them afterwards, as they aren't seen again. It is believed that they meet their ends from the massive explosion following Omega's demise.
- According to graphic designer Azuma Honda, the Four Guardians were originally supposed to be all blue since they were replicas of X. However, artist Toru Nakayama gave each of them different colors to emphasize their elemental attributes and help differentiate them in the game. Although the idea was initially met with resistance, it was eventually agreed upon.
- The Four Guardians can also be considered the "biological sons" of X, as they were born from X's DNA.
- For some time, the fate of the Four Guardians after Mega Man Zero 3 was uncertain, and the only indication was an image in Vile's Incident of the original X and the Four Guardians during what seemed to be the fall of Ragnarok. However, it was later revealed in an interview that the Guardians had died shielding Zero from Omega's explosion, and that the image in question was just a generous contribution from Nakayama's part. When asked about the timeframe of the illustration, Nakayama expressed that he was unsure, and Takuya Aizu jokingly acknowledged that the timeframe and events of the illustration were a little fuzzy, so they just threw it in there.
- Originally the X-Hunters were called the Four Guardians as well, before a female Counter Hunter and Violen's second form had to be removed due to memory limitations of the SNES cartridge.
