Greek gods and their Roman counterparts. Roman gods and goddesses, as compared to their lively Greek counterparts, lacked personality, were never seen in human form, and were concerned with civic duty.
Hiccup is my favorite character. ♡ I wished there would be an episode where Hiccup gets amnesia and the other Riders have to reteach him about Dragons. Of course, it ends in disaster as Hiccup is the best in the Dragon business.
