Gregar

Gregar is a Cybeast who was born of the same method that made Gospel, which is why they are so similar in appearance. However, the accumulation of bugs was natural and not man-made.

When he was born, he attacked and destroyed the Net and everything in it. As a solution, scientists invented Falzar to fight it. One day when they were fighting, they got close to the Underground, where they were trapped.

Gregar was released by CircusMan.EXE and went rampant. MegaMan.EXE tried to stop him but he had took over MegaMan.EXE through Beast Out. The first time he did that, he rejected the Healing Water and nearly deleted HeatMan.EXE in one shot. Dr. Hikari says after he takes over MegaMan that whenever he awakens, there is a chance that he may take MegaMan over. Were he to take complete control, even if Yuichiro Hikari did everything he could, he may have no choice but to have MegaMan be deleted forcibly. But he didn't, MegaMan obtained Beast Out. He is later placed in a giant Copybot but is deleted by MegaMan.EXE or Colonel.EXE and Iris.EXE depending on which version of the game you play.

Gregar is the final boss of the Gregar version, and its side of the field cannot be Area-stolen. If you happen to lose Area through use of Colour Point or Double Point, Gregar will not move forward. It also appears to be capable of standing over holes. Gregar sports 2500 HP in its normal version, and 4000 HP in its SP version. It is capable of the following attacks:
 * Rubble Rain: Gregar jumps up and two rocks rain down on your area when it lands. After repeating this for 2-3 times, it will follow up with one of the following attacks:
 * Gregar Thunder: Gregar fires its Elec Breath, hitting the front of your area and your current row.
 * Gregar Fire: Gregar fires its Heat Breath, covering the panel immediately in front of it and the back two columns of your area.
 * Tail Vulcan: Gregar readies its tail and fires it up and down your column. In the SP version, this attack also tracks your current column as it is in use.
 * Gregar Wild Rush: Gregar disappears. Then, a 3x3 area just in front of your back column lights up. Its claws will slash that area, while its head will rush down your row. In the SP version this attack will destroy all chips and Program Advances you have loaded.
 * Gregar Rubble Charge: Used only in the SP version. Gregar roars, then charges down its row. Rocks will then constantly fall down randomly on your area, with one always tracking your position.
