The Rise of RizeGreymon!

In the past, Merukimon tried to take infant Keenan away from his adopted, Digimon mother, Frigimon, but she refused to give him up. Over the years, Keenan grew up happy under Frigimon's care and with Falcomon as his best friend. When Kurata, Spencer, Sampson, Yushima, and the others first came to the Digital World, they were attacked by Digimon. Really, though, the attacks were essentially Kurata's fault because he provoked the Digimon. Kurata opened a Digi-gate so he and the others could escape, but Spencer stayed behind to fight SaberLeomon. He was willing to risk his own return in otder to make sure his teammates could go back home. Spencer wound up in a battle with Merukimon. He finally convinced Merukimon that his team wasn't invading the Digital World but instead had come to study it and find a lost human child, Keenan. The mention of the boy made Merukimon realize Spencer was telling the truth. He broke off the battle and gave Spencer information on how to find Keenan. After his initial disastrous trip to the Digital World, Kurata returned to seek revenge against the Digimon. Armed with plenty soldiers and brutal weapons, Kurata's troops viciously attacked the Digimon - and deleted their data forever! Frigimon was among those who were destroyed. Keenan took the loss of the Digimon he considered to be his mother very hard. He became a warrior and vowed to defend Digimon against the hated humons. In the present, Kurata unveils his latest invention, Gizmon-AT. It's intended to finish the job he started years earlier. He wants to wipe out all Digimon! Marcus vows to stop him.
