The Final Weapon, Repliforce's flower-shaped colony for their Reploid-only nation.
Final Weapon (ファイナルウェポン) is a space station that acts as the final stage in Mega Man X4, and was intended to be the Repliforce's utopian, orbital colony independent from humanity.
History[]
This flower-shaped space station was constructed by the Repliforce to be their ideal, Reploid-only nation in the vastness of outer space. They built the Weapon after launching a coup d'etat against the human government for Reploid independence, and equipped it with a powerful energy cannon capable of decimating all of Earth with a single shot. Although they only built the destructive weapon in the name of self-defense in case the humans attacked them, Sigma wrested control of it from them so he could use it to destroy the planet.
After X defeated the traitor Double and Zero defeated Iris in the station, X confronted the leader of the Repliforce, General, defeating him in battle. Then, the Hunters confronted Sigma. They defeated him, but had no way to stop the Final Weapon. Luckily, the General came by, and sacrificed his life to save the Earth by slamming his body into the weapon, ending the threat once and for all.
Stages[]
Final Weapon Stage 1[]

The first area is an onslaught of enemies down a tunnel through the Final Weapon. It leads to a room with a battle against the player's operator: Double for X, Iris for Zero. Once the boss is defeated, they do not have to be fought again on return visits to the stage.
Afterwards, there are two paths leading to the stage's true boss, General. The higher path is platforming across spike traps, while the lower path features pits and a Ride Armor Eagle before General's boss chamber.

Death Flower
The Final Weapon appeared in the Rockman X4 manga with a role similar to the game. In the manga it is named Death Flower (デスフラワー), and its energy cannon is named Death Seed Cannon (デスシード砲). Double, the traitor from X's 17th Unit, activated the weapon to fire on the Earth after X defeated the General. Double then engaged X in battle, but was destroyed by X who used a Nova Strike attack with the Ultimate Armor. Then, General, realizing the folly of his ways, sacrificed his life to save the Earth by slamming his body into the weapon's energy cannon.
