Ep. 20: El terremoto de MetalGreymon golpea mientras Tai y Koromon regresan a Tokio

After a night of formulating a rescue plan, Matt, T.K., Mimi, and Joe distract most of Etemon's forces while Tai and Izzy infiltrate the pyramid to save Sora. As Izzy and Kabuterimon hold off Etemon, Tai musters his courage and saves Sora as she was about to be killed after Datamon created a subservient clone of her so that he can use Sora's Crest and Biyomon to destroy Etemon. As the DigiDestined escape the pyramid and he gets attacked by Etemon, Datamon activates the Dark Network to absorb the data of anyone caught its gravity: including himself and Etemon. However, Etemon survives yet fused to the Dark Network from the waist down as he intends to use his power to wipe out the DigiDestined. When Tai and Greymon stand up to Etemon Chaos, the former's crest causes Greymon to digivolve to MetalGreymon to fight him. The battle ends up opening a portal that sucks in Etemon Chaos while transporting both Tai and a regressed Koromon to Tokyo. (Source: Wikipedia)
