LaserMan.EXE

LaserMan.EXE is a NetNavi operated by Dr. Regal. He is effectively the Navi in charge of Nebula, who was deleted at the hands of MegaMan in his attempt to control the asteroid that contained Duo near the end of MegaMan Battle Network 4. He is an ambitious and dark NetNavi. In the manga, he is a Darkloid, but in the anime, he takes command over them after overthrowing their previous leader, ShadeMan.

Mega Man Battle Network 4
LaserMan was first encountered after Lan wins The Eagle/Hawk Tournament. He prevents Lan from leaving and offers MegaMan the chance to join him. MegaMan refuses and is about to fight LaserMan when one of his friends arrive (GutsMan in Red Sun or AquaMan in Blue Moon). LaserMan then fuses MegaMan's inner darkness with the other Navi, forcing the player to do battle with the DS (Dark Soul) version of the Navi. Then LaserMan retreats, saying the darkness had already grown inside him. Later Dr. Regal jacks him into Duo's comet in an attempt to take over the comet, and when MegaMan and LaserMan meet in the comet's cyberworld, they battle. LaserMan is eventually defeated and MegaMan proceeds into the control area of the comet.

Anime History
Much like his video game counterpart, LaserMan serves as the NetNavi for Dr. Regal, with the additional detail in that he also becomes the new leader of the Darkloids as well after overthrowing their previous leader ShadeMan.

Mega Man NT Warrior
LaserMan is a Darkloid and mysteriously appears along with Dark MegaMan at the end of volume 7. He assists Dark MegaMan in gaining enough hatred energy to allow him to fuse with Bass. LaserMan is later defeated by ProtoMan and consumed by Dark MegaMan after suggesting that they retreat. He never appeared again in the manga. It should be noted that even after fusing with Dark MegaMan, he still lost to MegaMan.

Abilities
LaserMan's battlefield contains a Mystery Data at the lower back corner of his area, whilst fighting his Omega version. This contains a Giga Chip which varies depending the version of the game being played. In the Blue Moon version it's Bug Curse, while in the Red Sun version it's Bug Charge.
 * Super Armor: LaserMan cannot flinch.
 * Cross Laser: LaserMan fires a laser centered two squares ahead. The center square is cracked, and the laser spreads in a + formation. If he fires it into a hole, the laser will not spread.
 * Star Break Laser: LaserMan fires a laser upwards off the screen. Rocks then fall on the player for a set time.
 * Power Down Laser: LaserMan holds out his hand. Shortly after, time will freeze, and he fires a powerful laser down his row. It removes Invis if it connects, but does not pierce it. This attack uninstalls random Navi Customizer parts if it connects.
 * Dark Laser: LaserMan fires a laser, creating a Dark Hole. While the Dark Hole is present, regardless of whether he generated it or a player created it via chip use, his health will slowly regenerate.

Trivia

 * His quote right before fighting MegaMan in Battle Network 4, "Prepare to become space dust!" is the same quote said by Sigma during the final boss battle in Mega Man X4.
