"Squeak! This is GREAT! Very funny! The Earth has been severely damaged... Very cool, brother! Squeak! Let's retire all of the Reploids together!"
―Dark Necrobat, Mega Man X5

Dark Necrobat (ダーク・ネクロバット Dāku Nekurobatto), also known as Dark Dizzy,[2] is a vampire bat-based Reploid from Mega Man X5.

Necrobat was a Maverick created by Sigma three years before the events of Mega Man X5, but escaped from his control and remained in hiding since then. Sigma, not considering him a serious fighting power, forgot about him. The Maverick Hunters encounter him in a planetarium somewhere in northwest Sudan while they are looking for a Fuel Tank for the Space Shuttle. However, he proves to be a fighting serious power to both X and Zero, proving Sigma wrong indirectly.


In battle, Necrobat flies about, sometimes teleports, and can summon Batton Bones to attack the player. Like bats, he doesn't like light, and is weak to Shining Firefly's weapons, F-Laser (with X) or C-Flasher (with Zero). It is possible to defeat Dark Necrobat with a single F-Laser by hitting him only with its trail.[3]

  • While he's flying around, he may sometimes dive at the player, grab them and bite the player's character to drain his life energy, like a vampire.
  • If Necrobat is low on health, he will release Sonic Waves up and down the screen. After that, he will use Dark Hold to freeze the player and attack with either a Sonic Wave or Batton Bones. If the player hits Dark Necrobat while he is casting Dark Hold, he will be stunned and drop to the floor.

After his defeat, the player obtains his weapon, Dark Hold.

Production Notes

Developer Comments
"This was also influenced by a certain manga, so perhaps they asked the designer, "Please give him a Bat XXras feel!" (grin) [The character/manga he refers to might be Karas. The name is "Kohmori ??ras," where ?? is one kana blotted out.] However, as you can see from the results, he finished up as a smart design, and I really like it. Just before the game was completed, we discovered a bug that made the Dark Hold perpetually freeze the game. Gave me a real chill. (grin)"[4][5]

Designer Comments
"Being a bat, he was established as draining his opponents' energy, so in short, he was Count Dracula, and I gave him form straight from that. A monster in full dress. He's the only one this game to have the Sigma mark on him."[4][5]

"I shamelessly went for the Count Dracula look here. His right eye is a monocle, and he has a haughty air about him." -Haruki Suetsugu, Mega Man X Official Complete Works, 2009[1]


  • In the initial American release, Necrobat was named Dark Dizzy, after Dizzy Reed, the stage name of the keyboardist of the band Guns N' Roses.[6]
  • Dark Necrobat shows many similarities with Shade Man, a boss of the classic Mega Man series who is fought in Mega Man 7. They're both bat/vampire themed, use soundwaves as an offensive weapon, and have the same life stealing ability, although Dark Necrobat uses it very rarely.
  • His "Dark Hold" (ability to freeze dimensions) is the only special weapon in the Mega Man X series that doesn't have any higher power when X is equipped with an armor that allows special weapons to be charged.
  • In the game, he is the only boss out of the eight to have Sigma's Maverick symbol shown below his health bar.
