Many Digimon roamed the ocean, from Coralmon, invisible to the naked eye, to Seadramon dozens of meters long, and even Deep Sea Octomon, whose fully extended bodies could fill the hollow of a mountain. Unfortunately, none of these Digimon were truly powerful, nor were there any fearsome Ultimates among them. So Arukenimon used thirty Dark Towers to create three Ultimate Digimon—MegaSeadramon, Snakemon, and Wave Messenger—and shattered the Holy Stones deep beneath the sea.
At that instant, winds rose and clouds churned, and the entire world underwent a tremendous change centered on the Holy Stones. Astral gales shifted endlessly high in the heavens, while dark clouds slowly descended from the sky as though to crush the world beneath them. Bolts of lightning tore across the heavens with the howls of mighty dragons. Just then, a column of smoke curled up from the shattered Holy Stones, propping up heaven and earth all on its own. When the first Holy Stone had shattered, a finger-thick column of smoke had risen as well. This one, however, was as thick as an arm.
BlackWarGreymon and Agumon had finally become good friends. The two Digimon exchanged their combat experience. Most of the time, Agumon talked while BlackWarGreymon listened. Occasionally, though, BlackWarGreymon shared his own insights, and Agumon learned a great deal from them.
Just as the two Digimon were delighting in their new friendship and newfound knowledge, the distant upheaval finally reached them. Under Agumon's puzzled gaze, BlackWarGreymon suddenly stood and flew into the sky. It took Agumon another minute to barely sense the changes far away. By then, every trace BlackWarGreymon had left in the air had already vanished. This was a technique BlackWarGreymon had only recently learned.
