The devil fruit wizard

Igneel knew that leaving Natsu alone was a bad idea, but he never imaged that his son would stumble upon across a literal tree of supreme power as well as weapons and knowledge from an age long since past.

Now armed with that as well as his own dragon slaying magic Natsu Dragneel is ready to take the world by storm.

Stronger and Smarter Natsu.
