As Dr. Toro's elder son, he was formerly on the Blitz Team until Bit joined the group. Having been invigorated by Bit's latent potential as a Zoid pilot and confident that in his absence the team was in able hands with Bit, Leon left the group in hopes of becoming a better pilot. He later becomes Naomi Fluegel's partner. Leon pilots a Shield Liger at the beginning of the series and is later seen piloting a Red Blade Liger. The Zoids he pilots can serve as a parallel to Van Flyheight, Zoids: Chaotic Century's protagonist.
