In Ninja Gaiden II for the Xbox 360, the Nuclear Armadillo is the final boss of the "The Flying Fortress Daedalus" chapter. Early in the "Quickening Devastation" chapter Ryu crosses a lava-waterfall where two of them are waiting but shoot fiery projectiles and later fights those two simultaneously. In Ninja Gaiden Sigma 2 for the Playstation 3, Marbus is fought instead of two Nuclear Armadillos in the "Quickening Devastation" chapter.
