The two Cybeasts of Cyber City are immensely powerful Cyber Beings who are the main focus of the sixth Battle Network game. There are two Cybeasts in existence, Gregar and Falzar.

Gregar was created when an accumulation of bugs gathered in a single place, giving birth to a Multibug Organism, a similarly to the artificially created Gospel. It immediately went on a rampage after its creation, tearing apart and devouring all a manner of programs and Navis with his claws and fangs. It has been stated that it was able to shake the entire Net simply by roaring.

To counter this, Mayor Cain's ancestor created Cybeast Falzar in hopes of destroying Gregar. However, the authorities lost control of Falzar, leading it go on a similar rampage. It scattered data all over the Net and shredded programs with its massive wings and talons, bringing shame to Cain's family (and thus directly leading to the events of the game).

During their final clash they opened an enormous chasm into which they fell below, never to be seen until the events of the game where they are revived by Yuika and her navi Circusman.EXE in the name of Neo WWW. Circus Man manages to capture one of the Cybeasts, but is forced to flee before the might of the other Cybeast, forcing Mega Man to seal it within himself upon realizing that he couldn't defeat it. However, the beast would not remain contained without a fight, causing the hero to lose control on several occasions and nearly leading to his deletion on said occasions. They are finally deleted during a clash with MegaMan.EXE, Iris.EXE, and Colonel.EXE at the Neo WWW HQ, but not without casualties as Iris and Colonel sacrifice themselves to destroy the Cybeasts when the Cybeast Mega Man confronts attempts to possess him one final time.
