StarMan.EXE

StarMan.EXE (NovaMan.EXE in the English dub anime MegaMan NT Warrior) is a NetNavi and member of the WWW.

MegaMan Network Transmission
In MegaMan Network Transmission, StarMan is seen very early on in Global Net distributing the false Zero Virus vaccine which is actually the virus itself. He is confronted by MegaMan, but runs promptly, leaving MegaMan to face a Spikey virus.

He is seen again later in Gravity Area, where he is confronted by MegaMan once again in a boss battle, and is deleted.

StarMan's operator is never mentioned, so it is unsure if he has one.

Starman's personality is very calm, as he always seems on top of the situation despite being caught by MegaMan twice.

Battle Network 4.5
Starman is an unlockable character in the non-canon game Rockman.EXE 4.5 Real Operation.

Attacks
Although his typical strategy is to teleport whenever MegaMan is on the same aerial height as himself, he has a few separate attacks. He has some similar moves in Battle Network 4.5

Star Rain: StarMan will spin quickly and vanish, and star-shaped meteors will appear usually in a pack of six to hail across the field quickly, the only way to dodge is to reach the opposite side of the field that the meteors are hailing. In 4.5, StarMan will charge up energy, then send a star flying down at the opponent. It cracks the panel it hits and confuses enemies.

Star Rain2: Similar to the first attack, but instead of six he fires a wall of 50 meteors.

Star Arrow: StarMan loudly shouts "Star Arrow!" (in English with a thick Japanese accent), upon which golden arrows fly out from 8 directions of his body (Up, up right, right, down right, down, down left, left, up left). In 4.5, StarMan charges up energy to fire an arrow similar to how Roll fires her Roll Arrow.

In the anime, Star Man uses a black hole of sorts to summon all of his attacks, but it's shown he can also fire a Star Arrow "Roll" style as a basic defense.

Chips
StarMan: StarMan appears, executing his Star Rain attack on the area directly in front of him.

Star Arrow: MegaMan can fire a single star arrow forward, it starts slowly and gains speed quickly. Besides being used as a projectile, the arrow can also be ridden as a platform, allowing MegaMan to skip portions of stages.

Trivia

 * The Star Arrow chip is most likely a nod to the Super Arrow from Mega Man 5, as both function in basically the same way.
 * StarMan seems to be based off the classic "Little Green Men" design for the Martians. He also seems to be based on the classic Grey design often reported to abduct people
 * 1) Both have similar color and eye shape.
 * 2) Both are rather small.
 * 3) Both are malevolent.
