The earlier quote from theoi.com have helped giving me a better understanding. I’ve been confused and couldn’t understand why would the son of Zeus and Hera (even if as some other versions of mythology says, of Hera alone) could be “ugly”. After all, all gods and goddesses are supposed to be “beautiful”. That’s the other important trait besides being “powerful” that makes them different from man.
So in “MYth”, Hephaestus isn’t “ugly”… he was born small and weak. Abandoned by Hera, but fortunately good old Oceanus took him in and Thetis raised him…. and Hephaestus grew up to become a strong god.
Hephaestus wishes Hera would love him as a mother. Being such a gentle god, he could never bring himself to hate Hera even though she didn’t want him.
It may take a while before I work on a MYth comic for Hephaestus, but I will be sketching him occasionally. ^__^
