Hunter Base

The Hunter Base (ハンターベース) is the headquarters of the Maverick Hunters organization, founded by Dr. Cain to counter the rising Maverick revolts.

Mega Man X / Maverick Hunter X
Hunter Base is never seen in the original Mega Man X, but does appear in its remake Mega Man Maverick Hunter X. This Hunter Base is located in Abel City. It is never actually seen in-game, but X is in contact with a Navigator stationed there, and there are various scenes from The Day of Σ which take place there as well.

Mega Man X2
Hunter Base appears briefly during X's conversations with Dr. Cain in Mega Man X2. It is where the two meet several times throughout the game to discuss the movements of the X-Hunters and the reconstruction of Zero.

Mega Man X3
In Mega Man X3, Hunter Base is directly assaulted by Dr. Doppler's army and serves as the game's Opening Stage. The attack occurs after X and Zero had already been dispatched to help quell the Maverick riots in Dopple Town, forcing them to make a hasty return. They arrive in the midst of the siege and split up to cover more ground. However, X is captured by the traitorous Hunter Mac, and Zero must save him himself. X then continues and fights Maoh the Giant atop the building.

After X and Zero defeat the eight Mavericks in Dopple Town, they return to Hunter Base, where Dr. Cain tells them he has deciphered the location of Dr. Doppler's Laboratory. Hunter Base is also revisited in the cutscene that plays if Zero is taken out of commission by the battle with Mosquitus.

Mega Man X4
In Mega Man X4, Hunter Base appears as part of the Stage Select Screen. It is also where briefings before important missions such as the final stage occur. In X's story, Double can be seen in the background, and in Zero's story, Iris is in the background.

Mega Man X5
Hunter Base again serves as the Stage Select Screen in Mega Man X5, where various Maverick Hunter operators can be seen in the background. Additionally, it is where the Enigma cannon and the space shuttle are stored, and by extension it is the location where Dynamo challenges the Hunters to duels.

Mega Man X6
From Mega Man X4 to X6 and Mega Man X8, the base appears as the Stage Select Screen. In Mega Man X5 Dynamo attacks the base, and the battles against him also take place inside it. Mega Man X7 features the base during most of its cutscenes. In Mega Man X8, the base also appears at the R&D Lab option menu, as well as during Sigma's reveal cutscene.

In Mega Man Xtreme, the Hunter Base's Mother Computer is hacked and all of its data is overwritten, and the resulting fake data has sent the whole world spiraling into chaos.

In Mega Man X: Command Mission, Giga City's Central Tower is used as a Hunter Base in the battle against the Rebellion Army.

Mega Man (Archie Comics)
The Hunter Base has brief appearances in the comic series, being first seen in one panel from Mega Man #35. It also has an appearance in the special story "The Choice" in Mega Man Issue #50.

Rockman X manga series
The Maverick Hunter Base was heavily damaged when Sigma became a Maverick. A Neo Maverick Hunter Base is built in Doppel Town in the Rockman X3 manga.

Irregular Hunter Rockman X
The 17th unit headquarters is commanded by Sigma.

Trivia

 * Mega Man X is the only numbered game not to show any glimpse of the Hunter Base, which was compensated on its remake.
