Sypnosis
After traveling to Earth, Digimon pirate Mermaimon abducts a Digimon wizard named Hitazumon to use his magical key to go to Muranthias & free her fiance AncientVolcamon. The DigiDestined aren't about to let this happen, & so they upgrade to Turbo Digimon, since the Zeo Digimon won't be enough to take on AncientVolcamon. Meanwhile, practicing for a martial arts tournament, Cody injures his back, & later sends Trevor in his place to become to the new member of the DigiDestined & help the team on Muranthias, where they use the Turbo Digimon to destroy AncientVolcamon. An infuriated Mermaimon swears vengeance on the DigiDestined, & returns to Tokyo to terrorize it with detonators & evil Digimon.

After the defeat of AncientVolcamon, the older DigiDestined graduate from high school & resume their normal lives, but are attacked once again by a vengeful Mermaimon & her forces & an endless supply of detonators & evil Digimon that threaten the citizens of Tokyo.

A new twist into the story involves Seraphimon & Kokuwamon returning to Seraphimon's home dimension, thereby relinquishing the mentorship of the DigiDestined to the spectral Ophanimon (who is suggested to be Mermaimon's long-lost twin sister) & the street-talking Tentomon.

The DigiDestined are then joined by Shepherdmon, an inter-dimensional police Digimon who brings with him the "Millennium Message", a pivotal story arc which foretells the later events of Digimon In Space. The four older DigiDestined are then retired from duty, "Passing the Torch" to four new DigiDestined - A.J., Marcus, Holly, & Maya, while Trevor remains partners with Ballistamon.

The mysterious Lowemon, whose identity is never revealed & whose powers originate from Seraphimon, arrives on Earth in the nick of time. Mermaimon's brother Havocmon arrives, bringing with him a new Space Base for his sister & Machinedramon which steals TurboOmnimon. Lowemon, who becomes Maya's love interest, gives the DigiDestined new Rescue Digimon, & the DigiDestined later manage to retrieve the Turbo Digimon as well.

However, the end of the series brings tragedy & devastation as RescueOmnimon is self-destructed on A.J.'s command in a failed attempt to destroy GoldGargoylemon, TurboOmnimon is in turn destroyed by him & the Turbo Ram is rocketed into GoldGargoylemon's mouth, finally destroying him. Mermaimon & Sheperdmon leave for the Seraphimon's home dimension, which has fallen to evil forces (which later turn out to be D-Reaper & the United Alliance of Evil). Alone, the DigiDestined then find their Power Chamber under attack by Mermaimon's forces & are unable to prevent their base from being utterly destroyed, right before Mermaimon is summoned by a messenger from D-Reaper (who has captured Seraphimon) to leave Earth for the Cimmerian Planet. The DigiDestined are left with no choice but to follow in hot pursuit in a NASADA space shuttle, sans Trevor, who chooses to remain on Earth with his father.
