Different Dimension Battle IV
The Final Dimensional Duel IV/Alternate Dimension Showdown IV or Form Change of Fury (Japanese: 異次元決戦IV Different Dimension Battle IV or 怒りのフォルムチェンジ Form Change of Fury) is the 434th round of the Pokémon Adventures manga.
With Diamond defeated, Charon begins gloating that his opponent's strength has dropped by one. Charon begins tapping on Pearl's shoulder and mockingly asks if he should capture the currently injured Giratina, finish him off as well, or go and capture Regigigas. Furious from Charon's words, Pearl turns out to attack and states that he will never forgive him for what he has done. Before Pearl can attack, Charon retaliates with his Slowking, sending Pearl flying backwards. Laughing madly, Charon commands Giratina and Heatran to crush and burn Pearl.
Pearl quickly notices that Tru, Kit, Don, Moo, Lax, and even Rotom are all in tears over what happened to Diamond. Pearl tells Diamond to watch them as they go and get revenge for what Charon did to him. Although he knows he might lose, Pearl sends out his entire team and rushes in to battle with Charon alongside Rotom. Charon is shocked to see that they have acquired Rotom as well, but states that the group are just regular Pokémon and have no chance against two legendary Pokémon.
Suddenly, a large quake shakes from behind Charon, which turns out to be Reg, who has returned. Reg places Rotom's five appliances on the ground, and after looking at its Trainer, tells Rotom to use them. Rotom jumps into the lawnmower first and begins attacking Charon with a Leaf Storm as Mow Rotom. Next, Rotom freezes Charon and his Slowking with Frost Rotom's Blizzard. It then quickly changes from Fan, Wash, and Heat Rotom to finish Charon off with Air Slash, Hydro Pump, and Overheat.
Giratina leaps to attack from behind, but Reg quickly grabs it and throws it onto the ground. Reg summons up a gigantic bundle of snow and throws it on top of Giratina and Heatran. Giratina immediately turns into its Origin Forme and takes off into the sky and escapes back into the Distortion World. Charon decides that it's time to retreat and recalls Heatran back into its Poké Ball. Charon flies into the air, dodging Reg's attacks, and escapes into the Distortion World as well. A shocked Pearl notes that the hole has closed and wonders how Giratina changed its appearance.
The Pokémon Association Chairman and Dr. Footstep come running. The Chairman explains that while they were waiting, they had accidentally dozed off and woke up after hearing he commotion. Dr. Footstep immediately begins collecting footprints of Giratina, Heatran, and Reg. He notes that Giratina's footprints show that it is angry at being banished and wishes to causes destruction and dominate. From Reg's footprints, he can only read sorrow. Pearl states that he knows, and reluctantly tries to tell them what happened to Diamond. Before he can say anything, Diamond's body begins flickering and distorting, much to Pearl and the Chairman's horror. Diamond's body quickly disappears in a bright flash of light, leaving Pearl to wonder what Diamond just did.
On Route 224, Marley, with a Gracidea in hand, begins examining Oak's Letter. She states that if what Professor Oak wrote to her is true, then she can meet a certain Pokémon here. She begs for the Pokémon to come out and states that they need its power right now. The Gracidea causes a small bush to start moving. The bush reveals itself to be the mythical Pokémon Shaymin.
