Libra Scales, known as Libra Balance (リブラ・バランス Ribura Baransu?) in Japan, is the EM Wave Change between Geo's teacher Mitch Shepar and the FM-ian Libra. Libra was the one who combined with Mr. Shepar because he couldn't make up his mind about whether to keep to his ideals of fun learning and get fired or stop his ideals for the sake of his children.
