The instant Groudon and Kyogre appeared, piercing alarms rang out inside the Hoenn League building in Ever Grande City.
The sudden commotion immediately drew everyone's attention.
"What happened?" a League official demanded.
"Reporting, sir! We've detected massive biological signatures in the waters south of Sootopolis City. We suspect Legendary Pokémon have appeared."
The League official's heart sank, a terrible premonition coming over him.
South of Sootopolis City... wasn't that where the top-tier mystery realm was?
Legendary Pokémon had actually appeared there!
The League official dared not delay and immediately reported all the information to his superiors.
With such a major incident unfolding in the waters near Sootopolis City in the Hoenn Region, the Hoenn League wasn't the only one to detect it.
Biological signatures that powerful immediately drew the attention of all the major Leagues.

"Those two have actually come out!"
"The moment they meet, they're bound to fight. The fallout alone could do serious damage to the ecosystem. Should I intervene?"
After giving it some thought, Zygarde decided against it.
Not long ago, it had sensed Rayquaza undergoing Mega Evolution. It would leave those two to Rayquaza.
In the fathomless waters of the Kanto Region.
A large white bird opened its eyes, excitement filling them as it sensed those familiar presences.
"Another good show to watch."
"No, no, this is a little too far away. Not a good viewing spot. I need to get closer."
Lugia acted at once, beating its wings and speeding toward Hoenn's ocean
