The arm possesses superhuman strength, which it can also manifest through a larger, spectral arm. It is also capable of absorbing items of power, such as the Yamato or Evil Legacy, and manifesting their power.
Throughout the game Nero displays discomfort with his arm, hiding it from other people and even admitting to Berial that "it drives crazy". In the end he comes to accept it, telling God that he had resented the change, but now sees it as a tool to be used against evil. [Source: wikia]
