Dusk

Dark Miyabi (who also goes under the name of Dusk) is ShadowMan's operator. In the video games, he is an assassin for hire.

Personality
Dusk is a merciless assassin who will do anything for money. He showed little sadness when ShadowMan was absorbed into the Dark Galaxy.

MegaMan Network Transmission
Dusk had only the briefest of cameos in this game, appearing at the very end after the credits to inform ShadowMan about their new job with Gospel.

MegaMan Battle Network 2
He is hired by Sean Obihiro to destroy Yumland and then Electopia. It is stated in MegaMan Battle Network 5, very few members of Gospel in Battle Network 2 were even aware of his presence. Dark succeeds in the first in destroying Yumland's cyberworld but fails in destroying the Mother Computer and then leaves Gospel.

MegaMan Battle Network 5
In Battle Network 5, he joins Team Colonel to fight gainst Nebula. However, he first insists on testing Lan and leads him on wild games of tag throughout the Net and making him vacuum up all the clouds. After the test, Dark joins the team and helps them defeat CloudMan.EXE. In End City, he challenges Lan and MegaMan for the SoulNet server even though Dark wasn't under its influence. He participates in the raid against Nebula's base and loses ShadowMan to the Dark Galaxy but later gets him back when he returns to help MegaMan. After the battle is sucessful, he leaves Team Colonel, stating that he hoped they wouldn't be enemies in the future. And, so far, that hasnt happened.

He was also mentioned as the master of Dark Scythe in MegaMan Battle Network 6.

MegaMan NT Warrior
In the anime series, Dark had only been mentioned until the Stream series. He was hired by Gospel but only ShadowMan appeared, not Dark. Then he becomes part of the Cross Fusion team in Rockman EXE Stream. He also had cameo appearances during the Beast and Beast+ series.

In Beast+, he is first seen talking to Dr. Wily and putting a rather large bottle of liquor on the table. He is buried along with Wily under a pile of cans while they were sharing a drink. After Dr. Wily realized what Yurika and Captain Kurohige stole from him, Miyabi appeared at the Hikari household to alert Netto of the problem. While there, his gets stuck in an embarrassing conversation with Haruka HIkari (Netto's mother). After summarizing the situation to Netto, he and Shadowman team up with Netto and Rockman to fend of the beast viruses that are attacking R-Circusman and R-Diveman (in the cyberworld).
