In Diamond, Pearl and Platinum only, Dialga and Palkia were referenced as "mythical Pokémon" with a lowercase M, seemingly a subset of rather than a distinct group from Legendary; it should be noted that this was prior to the use of the term Mythical with a capital M from Generation V and onwards, and was a translation of 神話のポケモン mythical Pokémon rather than 幻のポケモン Illusory Pokémon, the latter of which is referenced by the currently-used English term Mythical.

The Lake Trio were then created to help control and calm Dialga or Palkia should they be enraged.

Each of the member of the trio have control over their own dimensions. Dialga controls time and Palkia controls space, two aspects of the that the Pokémon world, like our own, is a part of.

In the movie trilogy
Dialga and Palkia debuted in The Rise of Darkrai. In this, their two worlds, the Temporal World and the Spatial World, collided, leading the two to mistakenly believe that they were intentionally invading each other's territory. As such, the two began to violently clash, causing large distortions between time and space in Alamos Town. However, Palkia sustained injury when one of the pearls on its arm was cracked. Palkia then took refuge in Alamos Town and also wound up transferring the town to the Spatial World. Dialga then appeared before it once forced Palkia to reveal itself. The two then violently continued fighting in the town. Darkrai also intervened in their fight to protect the town, and Dialga and Palkia continued to fight with Darkrai involved, causing massive destruction around Alamos Town. However, and  soon activated the song Oración on the Space-Time Towers, which becalmed Dialga and Palkia, prompting them to end their fight. Palkia then restored Alamos Town to its original state, and left right after Dialga.

The same Dialga appeared again in Giratina and the Sky Warrior, along with Giratina. In this movie, it was revealed that the fighting between Dialga and Palkia in the previous movie caused many toxic clouds to appear in Giratina's Reverse World. Giratina, furious at the two for defiling its home, sought revenge on Dialga, attacking it violently near a lake and drawing it into the Reverse World. As the two battled, Dialga attempted to escape, but Giratina constantly kept pulling it in. However, the vortex caused by Giratina abducting Dialga ended up pulling a fearful into the Reverse World on accident. In fear of the situation, Shaymin ended up using, which opened up a portal, and Dialga escaped by locking Giratina into a time loop.

Giratina, seeking to regain its ability to traverse between the Pokémon world and the Reverse World, went after Shaymin. However, Shaymin was under the impression that Giratina wanted to eat it and thus was terrified of it. When Zero appeared, Shaymin forcibly opened up a portal using Seed Flare, in which Giratina broke free from the time loop and regained the ability to traverse between the two worlds. Zero, in his goal to take control of the Reverse World, used a special machine to absorb Giratina's powers, which almost killed Giratina until Newton Graceland hacked the database. Giratina then struggled to stay alive until Shaymin used to restore it to a healthy state. Giratina then helped Ash and Shaymin defeat Zero, and when Shaymin opened a portal to help everyone escape, Giratina restrained Zero's ship and caused it to malfunction. It then helped Ash out of the Reverse World, but then flew away, which Newton Graceland suspected must have meant that Dialga was nearby.

Dialga, Palkia, and Giratina all reappeared in Arceus and the Jewel of Life. When a harsh distortion appeared and almost got and  abducted into the vortex, Sheena appeared on the scene and used her mysterious power to summon Dialga, who arrived and saved Pikachu and Piplup, then destroyed the vortex with. However, its presence drew in Giratina, who was still enraged at Dialga; it appeared from the lake and violently attacked Dialga. Sheena tried to communicate with it, but its rage ended up making the process difficult. However, Ash appeared and called out to Giratina; when it recognized Ash, it calmed down. Then, Sheena communicated with Giratina, telling it that it misunderstood Dialga and it should not battle it. Giratina then returned to the Reverse World in peace. However, another distortion appeared and Dialga ended up being trapped in the vortex. Luckily enough, Palkia appeared and used to destroy this vortex, then bent space around Dialga to get it out of the vortex safely. Sheena then thanked Dialga and Palkia, and the two left in peace.

In this movie, it was revealed that the harsh distortions in time and space, and the subsequent conflict between the creation trio, was caused by the awakening of. When Arceus awoke and prepared to judge humanity as revenge for Damos' supposed betrayal eras ago, Dialga, Palkia, and Giratina all fought to protect humanity from Arceus, with Palkia bending space to restrain Arceus; and Dialga sending Ash, his friends, and Sheena back into time to alter the chain of events that caused Arceus's wrath. After history was changed and Arceus had restored Michina Town, the creation trio parted ways with Ash and, and returned to their respective dimensions.
