Ballistamon's Bad-News: Blast From the Past!

Synopsis
<!-- After finding out that is actually, a weapon created by , Xros Heart is shocked at the news. Olegmon tells them that when they had Zones, he built DarkVolumon in his Gold Zone to make a superweapon. During a test run, an accident occurred and DarkVolumon was sent into some other area. Then someone else changed the wiring to make it forget its purpose.

then recalls when he first met him. Shoutmon was fixing DarkVolumon while Lilymon and Jijimon were watching. He manages to fix Ballistamon, and the two begin to have fun with each other. Ballistamon thanks Shoutmon for repairing him, and Shoutmon asks him if he remembered what had just happened. Ballistamon then doesn't remember but tells him that it really doesn't matter anymore.

Olegmon does another check to make sure his creation only remembers him, and it works. Olegmon orders DarkVolumon to capture, but OmegaShoutmon tries to block him to try to get him to remember his friends. It doesn't work, so Christopher tells Deckerdramon and Mailbirdramon to attack. DarkVolumon grabs OmegaShoutmon, and Olegmon says its a shame to see friends turn on each other. He then calls his two demons out, Sutur and Jörmungandr, who approach the kids. Sutur asks them for a wish, and Christopher tells him he wants to defeat Olegmon. Sutur goes back to Olegmon, and Jörmungandr sends everyone but Mikey flying away.

On Olegmon's ship, Olegmon has hypnotized Mikey's Digimon. Mikey refuses to give in to Olegmon, so Olegmon tells him his chant works on Digimon only. Olegmon tells Mikey its up to him, also saying that he had picked him for a reason out of the the three. Mikey asks him why he didn't pick Nene or Christopher, and Olegmon tells him that he understands friends more better then them, and that friends are valuable. Mikey agrees with him and tells him he's the oddest Death General they've faced, but doesn't accept how he took Ballistmon away from him.

An upset Olegmon calls for two who have another Digimon, and shred the costume, revealing Nene. Olegmon is surprised that she came to help him escape, and Olegmon tells Mikey if he doesn't give him, he'll torture her. Mikey refuses, so Olegmon tells him he'll use DarkVolumon's ultrasound on her. In one of the lower decks, tells DarkVolumon that he's going to test on a human tomorrow, and asks him if he's ready to do it. DarkVolumon tells her he's a servant of Olegmon, so he'll do it. Somewhere else in Gold Land, tells Christopher that they've been blown far away from Olegmon. Shoutmon begs Christopher to fight with him, and after some persuasion by Deckerdramon and Mailbirdramon, he agrees to let him fight.

The next day, Olegmon's crew has tied Nene onto a platform. DarkVolumon is riding on Depthmon, and Olegmon tells him to use his soundwave on Nene. Olegmon tells Mikey that through him, he can turn his chant into a destructive soundwave. He turns it into level 2, and Mermaimon tells Mikey she won't survive at level 3. Olegmon gives Mikey one more chance to be his underling, but Mikey answers too late so Olegmon starts it up. Just as he is chanting, Mailbirdramon drops Shoutmon, who tackles Olegmon.

Christopher lands on the ship and unties Mikey. Mailbirdramon grabs Nene, and the latter thanks him. Christopher asks Mikey if he's a good swimmer, so he reloads Deckerdramon, and due to his weight, it topples the ship, sending everyone on it into the gold sea. Mailbirdramon attacks Olegmon's crew, and back on the platform, Shoutmon is trying to fix DarkVolumon to get him back into Ballistamon. As he is doing so, the two demons, Sutur and Jörmungandr lift Olegmon back up, who thanks them. Shoutmon barely dodges Olegmon's attack, and asks Mikey to DigiFuse him and DarkVolumon. Mikey doubts if he should do it, but he does after Shoutmon tells him to.

In the fused Shoutmon X2, Shoutmon is busy looking for Ballistamon. He finds Ballistamon crying, who tells him that he was meant to be a bad guy. Shoutmon refuses, and tells him that he needed to save him and that they're partners. Shoutmon asks him to be honest, and tells him if he would like to be DarkVolumon or the fixed Ballistamon. Just as Ballistamon is about to tell him, DarkVolumon takes over and the two defuse. Olegmon orders DarkVolumon to attack Mailbirdramon. As he is doing so, Mikey and Shoutmon call for Ballistamon, and DarkVolumon stops.

Olegmon wonders if DarkVolumon is malfunctioning again. Ballistamon tells him he's sick of his chant and punches him, and then picks up Shoutmon, telling him he likes the repaired Ballistamon. Shoutmon then uses his mic to tell the hypnotized Digimon to wake up, and Ballistamon amplifies it. The hypnotized Digimon are then snapped out of their hypnosis, and the kids DigiFuse their Digimon.

MetalGreymon and JetMervamon attack Olegmon's crew, while Shoutmon X4S fights Olegmon. As Olegmon attacks Shoutmon X4S, Mermaimon calls for Olegmon before being deleted. An enraged Olegmon vows revenge on Xros Heart, and the two demons pop up again, who knock MetalGreymon and JetMervamon away. The two demons are then empowered by Olegmon's secrets, and Olegmon wishes for Shoutmon X4S to get sent to spacetime. Ballistamon then defuses, defusing everyone else, and uses the soundwave Olegmon had put in him.

Sutur and Jörmungandr are sent into the spacetime portal, and Olegmon begins to get deleted slowly. Olegmon congratulates Xros Heart for defeating him and telling them friends are important before he dies. A few days later, Olegmon's ship has been fixed. and tell Xros Heart they'll use the ship to help out other Digimon. The ship then goes under the sea as Xros Heart heads to fight the next Death General. -->
