Why is Hades missing an arm?

In Greek mythology, Hades is not typically depicted as missing an arm; however, some modern adaptations and retellings might depict him with injuries or missing limbs for dramatic effect. One notable interpretation comes from the video game "Hades," where characters may have altered appearances or backstories that diverge from traditional myths. If you're referring to a specific narrative or adaptation, please provide more context for a precise answer.
