U-8 (Resident Evil 5)

This massive B.O.W. was produced as one stage of Tricell's Las Plagas bio-weapon research. It integrates DNA from several different species, crustaceans most prominently. Its durable armoured shell was proven in Tricell's tests to withstand even direct hits from anti-tank rocket launchers, but the rapidity of its mutation allows for faults in its armour which can prove to be a fatal flaw. The U in U-8's name stands for "Ultimate".
