All three Legendary beasts are revered as the guardians of Crown City. As such, they sensed Crown City was under attack and rushed to defend it when Zoroark was attacking the city in illusions of its destruction under the guises of the Legendary beasts. After reaching Zoroark, who had stopped destroying the city and was recaptured by Grings Kodai, Entei, Raikou and Suicune began attacking her, angry for the destruction they believed she had done.
Zoroark, who was trying to make her way to Zorua, fought against the three Legendary beasts through town, shape-shifting into Entei, Raikou, and Suicune to counter their attacks, but was outmatched by their power; although she was able to hold her own. When the Legendary beasts cornered the slightly injured Zoroark, she unleashed her Night Daze attack upon them, temporarily blasting them away, and continued her way to where Zorua was.
The Legendary beasts caught up to Zoroark near the park and surrounded her to attack again, but she retaliated by trapping the three beasts in an illusion of crystallized thorns. The illusion was quickly broken by Rowena's illusion canceler, and the Legendary beasts were freed, but were still ready to attack Zoroark. The wild Pokémon that took shelter quickly stood between the guardians of Crown City and Zoroark, trying to explain to Entei, Suicune, and Raikou that Zoroark wasn't the enemy. When the misunderstanding was resolved, the Legendary beasts appeared and stopped Kodai from reaching the Time Ripple, driving him away deeper into the Pokémon Baccer World Cup stadium. They later stood by when Celebi revived Zoroark back to life, who was mortally injured by Kodai, and watched as Zorua was reunited with his mother.
When Zoroark and Zorua were on their way back to Unova, the Legendary beasts were seen on a cliff nearby, overlooking the ship that carried the Illusion Pokémon. The three of them roared their final farewells to Zoroark and Zorua, before they departed separately into different parts of the area.

In the games
Three Shiny Legendary beasts were distributed in various countries worldwide to commemorate the movie. All three know four moves they would not normally learn in-game, all hold event-exclusive Berries, and all are three of the few event Pokémon with predetermined Natures (which cannot be changed by any means), with Raikou being Rash, Entei being Adamant, and Suicune being Relaxed. Transferring any one of these allows players to obtain a female Zoroark in Pokémon Black and White.
