Rockman X4 (manga)

Rockman X4 (ロックマンX4) is a manga by Iwamoto Yoshihiro based on the game of same name. It was originally serialized in Comic BomBom from September 1997 to August 1998 in 12 chapters, and later compiled in two volumes in 1998. However, as each volume had five chapters, the last two chapters were not included in the compilation due to complications with Comic BomBom, leaving the story incomplete in the volumes. The last two chapters were later included in the 2005 release from Fukkan, which also included new pages to the penultimate chapter, the battle between X and Magma Dragoon.

Story
The story continues from the Rockman X3 manga.

Suspicion
Suspicion (疑惑) is the first chapter from the manga, originally published on September 1997.

The Maverick Hunters are celebrating X's return, with X seeing Dr. Cain and Zero again and meeting Double. However, the party doesn't last long as the nearby city is attacked by the giant Mechaniloid Eregion. X immediately calls out his Hunters from the 17th Unit to help him, and Zero pitches in with help from the 0th Unit. X delivers the finishing blow to Eregion, while Zero saves a mysterious girl who was injured in the attack. Then, Repliforce field commander Colonel arrives and reveals that the girl is his sister, Iris, and thanks Zero for saving her. However, Colonel is suddenly snared with electrical chains from a hunter's gun, and Double from the 17th Elite Unit of the Maverick Hunters runs up to Zero, showing a piece of equipment with Repliforce's insignia on it that was spotted next to the Mechaniloid's corpse, and accuses the Repliforce of being involved. Zero then sternly demands for the Colonel to explain himself. Colonel angrily breaks free of the chain with his saber, and refuses Zero's request to disarm, saying it would be dishonorable to do so for a soldier such as himself. He then leaves the scene with Iris, although he still says he wowes Zero one for saving her.

Uprising
Uprising (蜂起) is the second chapter from the manga, originally published on October 1997.

Fallout continues from Eregion's attack on the city and the suspicion that Repliforce may has been responsible. The number of human fatalities is rising, and public sentiment has turned against the Repliforce as humans are demanding a reduction of their troops. The Maverick Hunters continue to investigate the scene and search for any more evidence to see if Repliforce was truly responsible. Zero, in frustration, beats his left arm against the wall after a Training Room session, rendering it inoperable and needing a metal cast. Meanwhile, Storm Owl and Colonel have a meeting in the Repliforce conference room with the General, planning on what their next move should be. General says that since they have already made a "mistake" once, there will never be allowed to make a second in humanity's eyes.

X meets up with Zero, and informs him that the human government has decided to temporarily disband and disarm Repliforce while the Maverick Hunters continue their investigation. However, the day before that was supposed to happen, Repliforce blimps and airships appear across the sky, broadcasting a message to humans from the General at the Repliforce Memorial Hall. Indigant at being accused of Mavericks after working so hard to support humanity, the General announces they will become an independent organization, and that they have already occupied many areas and main roads to aid in their rebellion. He says they shall fight to the end. This causes the government to declare the Repliforce as Mavericks.

Later, at the Hunter base, Zero is assaulting some fellow Hunters and announces that he is in agreement with the General's philosophy. X threatens to shoot him, but relents at the last moment, giving Zero the opportunity to slash him with his saber and incapacitate him temporarily. He warns X not to get in his way.
