ALL NOVEL 
A man from Earth was reincarnated as a Viking in Ragna village in the world of How to Train Your Dragon and through a few traumatizing events, he grew up to become a dragon killer and an enemy of Hiccup Haddock and his friends despite having enjoyed watching the films as a child and that's not all, he also gained an ability alongside his reincarnation which is destined to take him through not just the HTTYD world but other worlds as well.

3. The MC will travel to various worlds both books, movies and anime.
4. There will be a little romance and there will be no permanent partner who he brings along with himself in his eternal journey
5. The MC will experience a slow/medium growth rate in power and won't always be OP.
6. There will be a lot of killing (Gore as well if i can describe it well enough)
