"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 Dizzy, Mega Man X5

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

He 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.

Darkdizzy bites

Dark Dizzy bites X


In battle, he flies about, sometimes teleports, and can summon Batton Bones to attack the player. Like bats, he doesn't like light, and is weak to Izzy Glow's weapons, F-Laser (with X) or C-Flasher (with Zero). It is possible to defeat Dark Dizzy with a single F-Laser by hitting him only with its trail.[2]

  • 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 Dark 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 Dizzy 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.

When playing as X

Dark Dizzy: Squeak! I've been waiting for you!

X: Hey! Can't you understand the urgency of our present situation? There's no time to fight.

Dark Dizzy: Squeak! Who cares?! I don't take orders from anyone! The word 'Sigma' means nothing to me!

X: I'll destroy all Mavericks like you!

Dark Dizzy: Squeak! I'm always ready!

Dark Dizzy: Squeak! I've been waiting for you!

Dark Dizzy: Let's retire the Mavericks! Squeak!

Zero: You're one of them, I'll do you first!

Dark Dizzy: Squeak! This is GREAT! Very funny!

Going by Dark Necrobat, he joins Wind Crowrang in attacking the world of Billy Hatcher and the Giant Egg, but is defeated by its heroes and their new allies from the Sky Patrol.





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)"[3][4]

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."[3][4]

"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]


  • Dark Dizzy 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 Dizzy 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.
