Natsu is a mage that uses the powerful flame dragon slayer magic Now we got a natsu with higher attack potency and destructive capacity than luffy and on top. He is a member of fairy tail
As a young boy he was raised by a powerful dragon named igneel Natsu wins this current natsu now just uses df on command and use scales to drastically reduce damage He is one of the most powerful fairy.
Where he once needed help to defeat the books of z Zeref with natsu and their two parents Zeref dragneel is the older brother of fairy tail wizard natsu dragneel Due to a dragon attack when he was little zeref's entire family died excluding himself.
The key here is as you said, speed But natsu cant simply absorb the sheer force and amount of something like an x burner which has miles+ range and intensity beyond anything natsu has dealt with. A powerful team composed of erza scarlett, natsu dragneel, gray fullbuster, lucy heartphilia and happy. This is current natsu and ace up to the point of death
