<!-- Xros Heart United Army has reached the final land, Bright Land. sends to scout up ahead while they make their way to the tower. Sparrowmon returns, telling them an invisible force blocked her from getting up close and there's something else they need to see. They follow Sparrowmon, and find Digimon stuck on iron spikes, and head to one of the Digimon,. and try to get the spikes off Turuiemon, but he tells them that the spikes were forged by  and that they can't get it out.

Mikey asks the trapped Turuiemon if Apollomon is the Death General, Turuiemon confirms this. A beam of light appears, with and  coming out. Turuiemon tells Xros Heart to run, but they stand and fight. Sethmon calls for Bright Land's army to fight the rebels. Xros Heart fights the army, so Christopher DigiFuses and  into MetalGreymon. Xros Heart easily defeats the army, and Marsmon wonders if these are the people Apollomon is looking for. Sethmon calls for Apollomon, who appears and DigiFuses him and the army to become Sethmon Wild Mode.

Shoutmon mocks Apollomon for not showing himself. Shoutmon and MetalGreymon evolve into OmniShoutmon and ZeekGreymon, who then double digivolve into Shoutmon DX. Apollomon hurls his iron spikes to trap Shoutmon DX, and Sethmon attacks. Shoutmon DX easily destroys his spikes and counters Sethmon's attack. Sethmon decides to attack again, but Apollomon stops him and allows Xros Heart to gain audience with him. He orders for Marsmon to show them the way. Nearby, and  watch the battle.

In Apollonia Tower, Marsmon leads the way, while Xros Heart follows. Shoutmon gets tired and slips off the staircase, but Marsmon saves him from falling down. He tells him that if he fell down he would end up in Hell, and Shoutmon is wondering what's with the endless staircase. Marsmon tells them to hurry up and that if they wanted to see Apollomon, they had to walk up.

At the top of the tower, they find a beautiful field, and Shoutmon is upset that Apollomon had this all for himself. Marsmon tells them that the tower takes up the soil and places it up here, and that it came from the devil. Apollomon arrives and tells them trampling on the weak is the Bagra Army's way. Shoutmon is prepared to fight him, when Apollomon tells them of the heros who've fought from country to country. Apollomon knows who they are, and he reveals that he's actually a Digimon of Justice, shocking everyone. Apollomon asks them to join with him to fight against Bagramon and stop his plan, D5.

Ewan is busy waiting below the tower. At the top, Mikey asks Apollomon if he's actually been hiding his true nature from Bagramon. Apollomon confirms this, and tells them he's been accidentally made a Death General, but he hasn't forgotten who he was. He tells Xros Heart he has been waiting for heros to defeat Bagramon. Shoutmon asks him why he's treating his people like this, and Apollomon tells them he did it to prevent Bagramon from suspecting any good from him. Apollomon explains to the group that he's aware its sinful, but he doesn't want his people to be killed. Apollomon then tells the group that once there is enough negative energy, D5 will begin.

Apollomon waits for Mikey's answer. Mikey notices Apollomon has put a bandage on his right arm and that it is being deleted very slowly. Mikey then tells him to wait, and asks Christopher and Nene if they should help him. Christopher refuses, stating that he wants the Code Crown back so he can revive {{c|Deckerdramon|fu}. Mikey believes that Apollomon is telling the truth, so Christopher asks Nene. Nene says if D5 is real, if they work with him it will be helpful, but begins to wonder if he's lying. Christopher believes that Nene is just saying no and tells Mikey that its 2 to 1.

Inside the tower, Apollomon punches a wall in anger, believing that he asked too much for them to believe him. At the same time, he changes color. At the bottom, Damemon worries Apollomon is taking too long and that they should go up, but Ewan tells him to wait. Ewan then sees Apollomon, who kills Marsmon and has a different look. Up at the tower, Apollomon goes back to the kids to wait for their answer. Christoper has MetalGreymon attack Apollomon, and Mikey gets worried. Apollomon tells Mikey he'll withstand his attacks until he can trust him.

Shoutmon tells Mikey that he believes Apollomon is telling the truth. Mikey DigiFuses Shoutmon,, and  to become Shoutmon 4X. Shoutmon 4X grabs MetalGreymon to make him stop attacking Apollomon. MetalGreymon tells Shoutmon to stop restraining him, and Mervamon grabs Shoutmon 4X, telling him to calm down. Mikey tries to restrain Christopher, but he overpowers him and sends him flying. MetalGreymon uses "Giga Destroyer" and Mikey is in the attack's path. Everyone is in shock, but Apollomon grabs Mikey and protects him from the attack.

Christopher asks Mikey if he's ok, and Mikey tells him he is. Apollomon's bandage falls off, showing his wounds. Mikey asks him why he has those wounds, and Apollomon tells him that he did it out of atonement for punishing his citizens. Christopher then believes Apollomon, and he thanks him for believing in him. Rumbling is heard and Tsuwamon arrives with Ewan. Apollomon wonders how they got in, since even with DarkKnightmon's power they wouldn't be able to reach the top floor. Ewan tells him that he invited them in, and Apollomon refuses to believe what he's saying.

Ewan then remembers he forgot to tell the true Apollomon his other side, and tells him he also killed Marsmon. Apollomon still refuses to believe it and something manifests at Apollomon's head. The manifestation covers Apollomon's right side and introduces himself as Whispered. Ewan tells the other side that Whispered is a program that was dormant and placed by Bagramon and DarkKnightmon incase Apollomon didn't listen to them, and that he was trying to make a secret rebellion. Apollomon refuses to believe what Ewan is telling him, but Whispered tells him its true. Whispered then takes over Apollomon, and Mikey calls out for him and to fight back. Apollomon apologizes to Mikey, telling him he never knew of Whispered and that Christopher's suspicions were true. He tells Xros Heart that if they have to, they should kill him.

Shoutmon X4 tries to attack Whispered but is repelled. Whispered then traps them in a barrier, and Shoutmon X4 tells Mikey they need Shoutmon X7. The Digimon defuse, and Mikey tries to digivolve Shoutmon, but fails to. Christopher grabs Mikey and tells him what he's doing, but it's too late and Whispered sends them down to Hell. Shoutmon wonders if they're going to Hell, and Starmon confirms this. Mikey thinks to himself that it's his fault due to not evolving Shoutmon to fight because killing Whispered would kill Apollomon.

Tsuwamon, Ewan and Whispered look down at the hole. Ewan asks Whispered to join him into fighting Mikey and his group, and Whispered agrees with him.
