Ben, Gwen, Kevin, and George try to stop Dagon's resurrection, but first, they must defeat the demon's herald: Vilgax, now merged with a Lucubra and is much stronger than ever. To make matters worse, Dagon releases a wave that transforms everyone on the planet into an Esoterica, save Ben sinhala cartoon, Gwen, Kevin, George, Julie, and Ship. Gwen is briefly turned against her allies due to her previous psychic enslavement by a Lucubra, but Kevin is able to restore her human mind. Unfortunately, the combined efforts of Vilgax and a possessed Gwen manage to break the seal, releasing Daigon at last.
