The cyclopean Deltabeast holds a particular honour (by the standards of Planet Doom); while other robeasts had previously pierced Voltron's armour or come close to severing one of his limbs, the Deltabeast actually succeeded in doing both. With the unholy guidance of the Witch Haggar, it actually severed Voltron's right leg! This robeast appeared primarily in the thirty first episode The Sincerest Form of Flattery, with a brief cameo before being rebuilt into the Omegabeast in the thirty second episode A Transplant for Blue Lion.
