Quote from DeltaForce502nd:
Mecha Ridley takes 30 missiles, 10 for the glass shield and 20 to destroy the body(or 6 super missiles) [...] 100% run with 30 for glass shield and 60 to destroy body(or 18 super missiles).
Mecha-Ridley actually takes 28 missiles (10 for glass shield, 18 to destroy itself) and both of those are tripled in 100%
