Ep. 48: Suppression Army plans disrupted by Georg's return and Ra Kan's sacrifice against Bio-Tyranno.
Aired on March 12, 2006

48
The Suppression Army intends to reveal machine pilots to Digald soldiers to turn them against Jiin, but Georg attacks before completion. Zairin, sharing rebel ideals, helps transmit a message to Digald troops. Bio-Tyranno and Bio-Tricera launch an assault, prompting Ra Kan to order a retreat while he remains to confront Georg. Ra Kan deliberately allows himself to be wounded to penetrate Bio-Tricera's defense shield. He then executes a kamikaze attack, destroying both himself and Georg in the process. This self-sacrifice eliminates the immediate threat posed by the enemy forces and their mechanical allies during the conflict.
