According to rumor from 2ch, the villain group, Vaagrus, is composed of the following:
Master Delete- the commander of Vaagrus. A hologram in the form of a "digustingly cute" insect's head.
Sentouin Nanosoldier- The apparent minions for this year. As shown in the promo, purple/silver, and very Hakaider-esque.
Toshin Daikaijin MegaFighter- The apparent monsters for this year. Listed currently are β-１ and Ⅹ-１０ (Beta-1 and Chi-10)
Kyodai Heiki GigaMonster- The apparent giant-sized machinations for this year. Seems we'll be getting something Dekaranger-esque. Separate giant monsters. Listed currently is BlackΣ (Black Sigma)
Enter- humanoid warrior. Looks like George Makabe from Janperson.
