I think it would be cool if people made fan-made heros that are based on gods and deities of different beliefs. For example:
Raijin and Fujin from Shinto (Japanese)
Zeus or other members of the greek/roman pantheon
Ganesha or Vishnu or some other hindu god
maybe Ah-Puch or some other mayan god
Thor or Loki from the norse pantheon.
I hope that people will take these ideas and try to make some good ideas. If you don't know what these deities "look" like, earch up what they look like, also if there are more deities or gods that you would like to make, then go for it! Good luck!
