"Interesting. Could all these gods be each other's alter egos?" The gods' different identities suddenly made Shen Fei consider that possibility. Looking at mythology and legend, many regions' myths had absorbed and transformed those of other places. He had always been curious about that, unable to understand why it happened—but if they were simply putting on new identities, it made perfect sense.
Just as the Nine-Tailed Fox Daji had become Tamamo-no-Mae after going to Japan. Taigong Wang had confirmed that himself. Then what if other gods—or monsters—went elsewhere? They could simply take on different identities as well. That would make it easier to understand why Sun Wukong and Hanuman, as well as Nezha and Li Jing, had corresponding legends in India.
What had mainly given Shen Fei that idea was his experience in Olympus. Afterwards, he had looked into Greek and Roman mythology in detail, and combined with Caligula's attitude at the time, he could not help reaching that conclusion. After Greek mythology declined, the Greek Twelve Olympians had gone to Rome and continued being its twelve chief gods.
Gods were not immortal. Twilight of the Gods existed in quite a few mythological systems. Naturally, no god would want to face such an end. Even if Twilight of the Gods was inescapable fate, why not change identities? For example, if Greek mythology faced its Twilight of the Gods, what did that have to do with Roman mythology?
Take Zeus, for instance. According to Greek mythology, he was destined to be replaced by the fourth generation of divine kings, just as he had slain the third generation of divine kings and taken the throne before him. To prevent that, Zeus had even swallowed Metis, just as his father Cronus had swallowed his own children. Dragon slayers becoming dragons was hardly uncommon.
