Suggested by JHG195 It’s a double debut in this match as 2 new dragons enter the fray. Of course, Haku also has his human mode and knows some telekinesis which will help him out. If they both fought in their dragon forms Vermithrax would definitely win so that is why the human form is so important here. It will give him more agility and will allow Haku to block the larger dragon’s fire. It’s a tough fight, but I think Haku’s abilities are developed just enough to win this fight. Haku (Spirited Away) wins.

As someone who loves both the European dragon and the Chinese dragon, the Chinese dragon is far more powerful. It has godlike abilities, can control the elements and can even speak to people in their dreams. Now guess which one Haku is based on?
That’s true as far as the legends go the Chinese one would win, but I don’t think Haku ever got to use the full range of abilities you mentioned. I haven’t actually seen the movie but just from what I read I didn’t see any mention of those powers
