Professor

The Professor (real name unknown) is the main antagonist for much of Rockman.EXE Beast+. A strange and mysterious man, the Professor was once a researcher for the WWW who left when Dr. Wily disappeared and was thought to be dead, starting his own research lab. He hopes to leave his mark on the history of the cyberworld, and as such extracted the Beast Factor from the Super Cyber Beast after it was destroyed and evolved it, turning it into a beastized virus that can form in the real world. He is behind the cybernetic plants infesting the real world and Zero.EXE is his subordinate.
