Seasons & episodes

The NetSavers and Lan's friends have devised a plan to bring ProtoMan back from the darkness with a VaccineChip. Luring him into a trap at a deserted hotel, the plan is put into motion, but the chip fails. Chaud performs CrossFusion with Dark ProtoMan to try and cure him, sending the two into a world of memories where they battle with the darkness. The darkness is eventually alleviated, but Chaud and ProtoMan are both hospitalized after the battle.

Revived, ShadeMan plans to get revenge on Dr. Regal. First, he captures Rush and uses his technology to appear in the real world without the aid of a Dimensional Area. He goes on a rampage through DenTech City to find Dr. Regal, but Lan intervenes. However, once Dr. Regal appears, he unveils a tower of Dimensional Area Converters and covers the entire planet.

Dr. Regal uses a Dark SynchroChip to fuse with his NetNavi, LaserMan, and then proceeds to rip ShadeMan to shreds. Then, giant-sized LaserMen begin attacking cities throughout the world. Lan uses DoubleSoul during CrossFusion to fight Regal, but it zaps his power. CrossFusion ProtoMan reappears to help fight, but Regal proceeds to attack the Sci-Labs. However, the pleas of the NetNavis' souls (powering the Dimensional Area Converters) revives Lan and he achieves FullSynchro, completely destroying Dr. Regal. With peace restored, everyone watches a night sky of shooting stars, including Ms. Yuri who claims "As one chapter ends, another one begins."
