Okay, Kabuto Rider Henshins.

By the this time, you'll probably begin to think tachyons can do anything. They cannot. They only travel from reality to reality. Anyways, back to the theory.

The belt is a perpetual motion machine- it can never lose energy unless it is discharged. A Zecter is just a mobile container of specialized nanobots. Those are the hexagons you see when a Rider henshins. However, the Zecter would be ridiculously heavy if all of the nanobots needed to cover a person from head to toe were contained within. As tachyons have already been established in the series, the Zecters use the extra energy provided by the belt to super-charge their tachyon generators and create an opening for the nanobots to fly out of and cover the user. The same applies with the other Riders. The armor for Masked Form, after Cast Off, is designed to self-destruct on impact, exploding if it's a Worm and imploding if it's anything else (they'd have DNA scanners built in to determine the impact site). Hyper Cast Off utilizes a tachyon charge which opens up a small rift in the space-time continuum, which will cause the Hyper Form armor to encapsulate the regular Rider Form armor.
