As the Disc Zone collapses, Mikey decides to evacuate the Digimon to the Warrior Zone, where they all have a night of rest and recuperation. Shoutmon, still troubled by his own weakness, awakens in the middle of the night, while Wisemon informs Mikey of a disturbing revelation. His warning comes too late, as a copy of Blastmon assembled from shards he planted during the battle in the Disc Zone attacks. Mikey digifusesShoutmon X4 to take care of it, but his attacks are weaker than usual, prompting Beelzemon to swoop in and save them. Blastmon deduces from the Monitmaon that they are in the Warrior Zone, which Mikey expects.
The night after, the Fusion Fighters tail after Shoutmon and Ballistamon and discover that Shoutmon's been training to increase his speed and power. Unfortunately, he isn't advancing as well as he could be, and it is at this point that Tuwarmon attacks them. He creates a local pressure field and fires shots at them, which Shoutmon finds the strength to deflect in order to protect his friends. At the end, Tuwarmon reveals that he was merely helping with Shoutmon's training—and just in time, as Blastmon punches his way into the Zone. Shoutmon X4B comes to face him, but they are evenly matched, with Shoutmon X4B both hampered and strengthened by the need to protect his friends. Nene and Sparrowmon come to the rescue. The results of Shoutmon's training pays off, as he is able to add Sparrowmon to the DigiFuse without strain, forming Shoutmon X5B, who defeats Blastamon and gains Mikey his Code Crowns.
Blastmon retreats and is mocked for his loss at the Bagra Army's Headquarters. Outside, AxeKnightmon meets up with his spy in the Bagra Army ranks: Damemon, who is also Tuwarmon, and tells him to continue his task of undermining the Bagra Army. Meanwhile, in the Warrior Zone, Mikey hears another DigiMelody and calls for the dying Digimon to tell them where it is.

ExVeemon Type: Mythical Dragon Special Moves Strong Crunch X Laser
Mikey: "First off, this Digimon's a Mythical Dragon-type, and he's a pure breed. He has really powerful legs and arms, 'cause he'd rather work out than eat. His attacks are Strong Crunch and X Laser. Yep, it's ExVeemon! How'd you do?" Monitamon: "I guessed it was a pro wrestler with wings! Do I win?"

Monitamon: "It loves muscle training more than three meals a day."
In the Japanese verison, when accusing Shoutmon and Ballistamon of stealing DigiBytes, Cutemon says "There is only one truth!" (真実はいつもひとつ!,Shinjitsu wa itsumo hitotsu!?), which is the signature quote of Conan Edogawa from Detective Conan. Both Conan and Mikey are voiced by Minami Takayama in Japanese.
