Ep. 10: Goodbye Yellow

Goodbye Yellow is the tenth episode of Choudenshi Bioman.

Plot
The Neo Empire Gear are ready with their best weapon yet; a gun that fires beams that completely negate the bio-particles in Bio Robo and the Biomen. The Biomen learn this the hard way when they fight a giant mecha and Mason zaps Bio Robo, leaving it defenseless! The Biomen are soon forced out and Mason tries to zap Red One! Only Mika (Yellow Four) takes the hit and soon suffers great pain. Peebo manages to rescue the Biomen, but Mika is M.I.A. Mika realized the gun already used up so much power, it'll soon be useless! The Biomen find Mika who is unfortunatly dying. Mason threatens the Biomen with the same fate as Mika. Mika, knowing she's dying anyway, pushes the Biomen out of the way and takes the rest of the gun's power. The Biomen avenge Mika by taking out the mecha! May she rest in peace.

Trivia

 * Last appearance of Mika Koizumi as a main character.
 * Yellow Four was never shown unmorphed in this episode due to Yuki Yajima quitting the show (the reasons why are unknown and there has been different theories on this). Also, her voice was dubbed over by an uncredited Mayumi Tanaka as Yuki Yajima had only completed ADR for the first nine episodes.
