Boma Doctor Lehda (暴魔博士レーダ Bōma Hakase Rēda, 1-30): A bearded mystic genius with an ammonite-like head and a human face. He is second in command. Intelligent and cruel, he hates humanity and his schemes always involve the use of human deeds against humans themselves and mass killings of humans as well. He is usually portrayed to be the kind of field commander who does not show up often and works closely with Great Boma Emperor Lagorn, receiving less ire and is entrusted with the most dangerous of operations. He is very skilled in witchcraft making him a powerful sorcerer. He was later sent to take care of the Turborangers with the Super Boma Beast when both Princess Boma Jarmin and Dark Boma Zimba died where he almost buried them alive seeking revenge for Lagorn, as he was entrusted. When he saw the Turbo Robo pass by, he used his efforts to lure Red Turbo out to a battle hoping to divide the Turborangers. In that battle, Red Turbo and Lehda duel to the death. He reveals his illusion powers from his cape in an attempt to wipe out Red Turbo even with the ghosts of Jarmin and Zimba. However Red Turbo managed to counter his attacks by slashing his cape, mortally wounded him and performed a GT Slash which inevitably killed him where he exploded violently as he uttered his final words in an illusion form cursing the Turborangers.
Lehda is very skilled in witchcraft and he is armed with the Demoinc Flute Clairvoyance Cane (魔笛透視杖 Mateki Tōshi Tsue) which double also as a flute, which with he plays a tune to summon a tornado that enlarge his fallen Boma Beasts. He has a cape that possesses illusion powers, like summoning the ghosts of Jarmin and Zimba in his battle against Red Turbo.
