Prowler serves as a dark counterpart to the “main” Miles Morales from Earth-1610B. He is a brooding, enigmatic, character, having lived through the death of his father, something that his heroic counterpart has yet to experience. He is quite apathetic, as he was not remotely fazed when encountering another version of himself and was casual in talking with him about his life. He also displayed no sympathy towards the fact that the Spot plans to kill his counterpart's father and home, even refusing to let his counterpart go, possibly he wanted his counterpart to have the same pain he went through. Despite this, Miles does seem to love his family, as it's heavily implied that he and his uncle were the ones who painted a giant mural of Miles' late father in his honor similar as to how Earth-1610B Miles and his dad did for their Aaron following his death. On that note, he seems to care for his uncle, signified by how the two seem to have their own handshake and how he supposedly took up the mantle of the Prowler after him. As it's mentioned in the official artbook that Miles is in fact a vigilante, this could mean that deep down he still strives to bring about good like his Earth-1610B counterpart.
