DA ep20 recap

Episode recap for The Earthquake of MetalGreymon.


Tai is still rather upset about his mistake, the group tries to keep him positive. Izzy uses his computer and discovers that Sora and Biyomon are still in the pyramid, which instantly raises Tai's spirits.

Meanwhile, Sora is trapped in a hidden room and Datamon begins to create a digital clone of her, which he plans to use to control her Digivice and Crest. This way, he can make Biyomon digivolve and take revenge on Etemon for imprisoning him. He also has the final Crest, which he puts in Sora's Tag.

The group devises a plan to sneak inside the pyramid without being seen. Tai wants to be the one to save Sora and receives the directions to the secret room from Izzy. He is scared to hear that he must pass through another electric fence, the thing that caused his last downfall. While Matt and Joe create a distraction, Tai and Izzy head into the pyramid through a secret passage. They take a few detours through the labyrinth inside the pyramid and are spotted by a security camera, however they didn't notice.

Meanwhile, Mimi leaves to help fend off the guards, leaving T.K. alone. Etemon attacks the DigiDestined outside and easily defeats all of the Champion level partners. He then starts singing, which causes them to de-digivolve. One of Etemon's henchmen informs him that the remaining DigiDestined are inside the pyramid. This brings him to the conclusion that Datamon must also still be there and while he is pondering this Mimi, Joe and Matt escape and return to T.K.

When Izzy and Kabuterimon are held up by an angry Etemon, it's left up to Tai to face his newest fear and pass through the upcoming firewall. Agumon's encouraging words help him pass through the electric fence, and his overwhelming courage causes his Crest to glow. He finds himself in Datamon's hidden room, face to face with Sora's digital clone. Tai then manages to steal Sora's Crest back from Datamon. Datamon opens up a hole in the floor underneath Sora, but Tai is able to save her from falling and returns her Digivice and Crest. Biyomon is then able to digivolve and Tai and Sora then escape the pyramid along with Izzy and their partners. They meet up with the others as the pyramid collapses after being battered.

Meanwhile, Etemon has also found Datamon who deletes the digital clone of Sora since it can't be of use to him without the Tag and Crest. The two of them plunge into Datamon's expanding hole in the floor and into the heart of Etemon's Dark Network. Many of the Digimon that were guarding the pyramid are sucked into the vacuum as the pyramid disintegrates. Datamon is consumed, but Etemon takes control of the huge ball of the Dark Network. He rises out of the pyramid, stronger than ever, to face the kids outside. Agumon, now Greymon, takes on Etemon with Tai by his side, but it isn't enough. Then Greymon digivolves into MetalGreymon because of Tai's courage and has no trouble defeating the evil Digimon. However, destroying the heart of the Dark Network creates a dimensional rift, sucking both Tai and MetalGreymon in.

Tai and Koromon find themselves back in the Real World, more specifically, in Tai's own neighborhood.

"How come I wanna throw up every time you say 'one more thing'?"

Tai is getting tired of complications.

Etemon: "What's going on here?!"
Gazimon: "Ikkakumon is bombing us!"
Etemon: "Well, bomb him back!"

—Etemon tells his minions the obvious course of action.

Tai: "Come on Izzy, lets move out!"
Izzy: "Roger."
Mimi: "He forgot his name!"

—Mimi's not too familiar with tactical jargon.

Etemon: "You're becoming a nuisance, son."
Joe: "Of course. It's because I'm a teenager."

—Joe puts Etemon in his place.

"It's the end of the line for you and your goat, baby!"

Etemon can't figure out what animal Ikkakumon is supposed to be either.

"Is that the best you've got? I've seen sharper needles in Granny's knitting bag!"

Etemon doesn't think highly of Togemon's Needle Spray attack.

"A man must face himself before he can face his enemies."

Tai discovers his courage.

Datamon: "Those were computer viruses I dropped into the black pit. It will keep growing and absorb all the dark energy of our cosmos, including yours, fool!"
Etemon: "You know how I hate bugs!"

Datamon's final revenge bugs Etemon.

"I'm not afraid of you, ya big blow-hard! Come down here and fight like a 'mon!"

Tai confronts Etemon one last time.

Greymon: "Tai! Your courage is giving me even greater strength! I can DIGIVOLVE! Greymon Digivolve to..."
MetalGreymon: "MetalGreymon!"

Greymon finally breaks the Ultimate level barrier and digivolves into his true ultimate form of MetalGreymon.

"No! You must not defeat me! I'm just too important to diiieee!"

—Even at the end, Etemon has delusions of talent.

"Koromon... I'm... I'm home."

Tai after being sucked through the portal.
