Voltes V underwent a heavy repair according to the mechanical scheme dropped by the mysterious red mechanical eagle. When it tried to fire Choudenji Ball, it turned out that the energy of Voltes V was drained to zero because the energy control of Voltes V failed. Once again, the mechanical eagle came to the rescue. To solve the energy draining problem, the mechanical eagle combined with Voltes by "Panel Seven" mechanism and implanted an energy control device in Voltes' back. Now Voltes can use Choudenji Ball at its disposal.
