A major recurring villain in the Rockman.EXE series. He is the adopted child of Mr. Wily alongside Ms. Yuri, and was made into a probe for Duo at the age of 15 along with her after a plane crash that only the two survived 20 years before the start of the series, making him roughly 35. He is the operator of LaserMan.EXE, and when merged with him becomes Cross Fusion LaserMan.

Regal resurfaces in the movie. After his defeat in Axess, Regal was thrown into the UraNet along with LaserMan, his body fragmented into bits of data. While there, he discovered the dormant Wily Program and merged with it to become Nebula Gray.
