Digimon Adventure tri.
Hearing of the possibility of a Digital World reboot and the Digimon would lose all their memories in such an event, Izzy creates the backup field as a counterplan to save the Digimon's memories. When the countdown for the reboot initiates during the battle against Meicrackmon, Izzy makes the backup field appear inside the Digital Dimension and instructs Kabuterimon and MetalGreymon to put all other Digimon inside it. Eventually, Tentomon is left as the last Digimon to attack their comrades and Izzy orders him to enter the cube. Tentomon refuses to be the only one to be saved and digivolves to HerculesKabuterimon ina an attempt to save everyone. However, he takes too long and fails to save anyone from the reboot.
