First and foremost, I think we should get it out of the way that the Greek gods you're referring to were what pagans used to worship. Just like how the arabs in the time of the Prophet Muhammad (saw) used to worship idols. Their existence is not real except in fictional books and movies. Believing anything on this planet is near godlike is shirk, something that should be avoided or you will be avoided Paradise. Second of all, Dajjal will only have the power to bring down rain and vegetation because that's one of his deceptions against human kind. The resurrecting part about the hadith is actually shayateen (evil jinns) who manifest themselves into people's dead relatives to fool them into thinking Dajjal is divine. No one on this planet has ever compared to Allah swt. For He is the Almighty "And proclaim: Praise be to Allah, Who has not taken unto Himself a son, and Who has no partner in the Sovereignty, nor has He (need for) any protecting friend through dependence. (17:111)
I hope this answer finds you well. Jazakallah khairen and have a wonderful rest of your day!
