Altered States (2) - S2.E24

The violent combination of Metabee and Warbandit's Medaforce blasts shakes the whole stadium, as, far beneath the arena, Rokusho and the Phantom Renegade discover that the Rubberrobo Gang's hideout has been beneath the Medadome all along. They discover a massive resonating antenna, and the Phantom recognises the truth, racing to tell Doctor Aki while Rokusho takes on a team of Whitesords.

Warbandit and Metabee, meanwhile, appear caught in a state of suspended animation, and, in a dream state, deep in the recess of his own mind, Metabee sees a world devastated by war. Victor and Ikki bring their Medabots around, but the strength of their robattle spirit is affect both their medals, and the medals of all the other Medabots around them - and the Phantom Renegade suddenly appears to explain why! The entire stadium is a gigantic resonance device, harnessing the energies of the rare medals and spreading it's effect to all the medals within.
