Slur

Personality: Slur is a cunning, arrogant, and incredibly powerful extraterrestrial NetNavi from the same planet as Duo that respects and serves him with the utmost loyalty, using the technology he provided to test humans and carry out his will. Slur also seems to possess a very high level of arrogance, looking down on all humans and Navis, including Forte, and had deemed them all inferior — even explicitly claiming that Forte was foolish in the two's first meeting. This arrogance is further highlighted by them choosing Navi operators guaranteed to utilize Asteroids either selfishly or with criminal intent, while seemingly ignoring the people fighting to prevent further conflict caused by them.

Appearance: Slur is am extraterrestrial humanoid NetNavi with a cyan body and light green linings on each side. They have red eyes. Unlike most other NetNavis, Slur doesn't seem to have a Navi mark.

Abilities: As a NetNavi hailing from a foreign planet, Slur's powers are heightened above and beyond those of most ordinary Navis and even Duo's Asteroids, being capable of levitating and traveling back and forth through the Past Tunnel with speed greater than the norm, and does not require any external assistance in transcending space-time. They are capable of tearing open portals in the Cyberworld to travel to any desired destination, as well. Slur's abilities can also be exercised from great distances and have been shown to reach Earth from Duo's comet in space. Their defenses are also virtually impenetrable, such as being capable of surviving injuries that would prove fatal to regular Navis, such as a triple Program Advance, a head shot, or a sword to the chest.

Many of Slur's attacks involve a living form of wiring that sprouts from beneath the Navi's sleeves. The wire can be shaped into other weapons — swords, especially — which instantly take on the appearance and density of the object in question. In addition, the wiring can be used to bind, strangle, and electrocute victims and does not necessarily need to be within close proximity, as they frequently conjure some wires out of thin air and sometimes from the Navis themselves, allowing them to be immobilized and easily assaulted.

Another of Slur's abilities involves harnessing the power of an aura. Often, they transform into either a sphere or a sliver of light to ram enemies. They can also concentrate the energy from the aura into concussive bullets projected from the palms of their hands or create a ring of this same force to cause explosions.

Slur is a major antagonist in Rockman EXE Stream. An incredibly powerful extraterrestrial NetNavi, Slur is the herald of Duo and distributes Asteroids to those with vulnerable hearts on his behalf and tempts them to cause chaos in the world as a test of the world's purity. Slur becomes the main enemy of Forte, who wishes to delete Slur to prevent the aliens from destroying the Earth, if only because it would also result in the destruction of Earth's Cyberworld.
