The known members of the Grösse family are all bosses with an affinity for heavy armor and dual Chain Guns. All of them drop gold keys upon death. In fact, apart from appearance and sounds created, their game mechanics are identical. Gretel Grösse appears to be very nearly a palette swap to Hans, having a nearly identical appearance save for color changes (and chest and abdomen differences). Trans Grösse, however, was created at a later date and is more unique. Whereas both Hans and Gretel hold their heads high with pride, Trans walks with a scowl, his head dipped in fury.
