I would personally love it if, instead of Hiccup, the movie would be focusing on his son or daughter, years later when he is married too Astrid!

However, I would hope he/she wouldn't suck at training Dragons. Because we then basicly get the first film again, only with training instead of slaying Dragons.

Someone I know once told me his idea of HTTYD3. Of Hiccup's Son sucking at Dragon Training, but then he meets a Night Fury and the Fury leads him to an entire island of Night Furies, where they are Controlled by a Red Death. They slay it, and return the Night Furies to Berk, Where the Son Become's a Hero...

...Sounds familiar?
