Natsu Dragion

Personality
Edolas Natsu has shown to have Alternative Personality Disorder, as he is extremely confident and rude on vehicle, while extremely shy, polite, apologetic, easily scared, and prone to crying when off. He also has a habit of adding "-san" to the names of people he talks to (He calls Wendy "Wendy-san" and Earthland Natsu "Me-san"). The change of personality shocked his counterpart, Earthland Lucy, and Happy the most. Due to the trauma that Edolas Lucy probably had inflicted on Edolas Natsu, he is quite fearful of Earth Land Lucy that even a simple greeting from her forced him to hide behind a rock. However, he did show emotions by blushing after knowing Earthland Lucy's cute personality.

Edolas arc
Just when Earth Land Natsu, Lucy, and Wendy was about to be captured by the Royal Army, Natsu Dragion (ナツ・ドラギオン, Natsu Doragion) showed up in his magic four-wheeler and saved the group from being captured. Revealing that he heard everything from Lucy from Edolas, he offered them to get on the vehicle, and in matter of moments, they escaped the clutches of the Royal Army. Upon reaching the wilderness, where they're safe, he revealed to the group that he is the fastest man in Fairy Tail, nicknamed 'Natsu the Fireball.' He is also the transport magic specialist.

He drives them to the Capital and leaves them remarking that is fearful of what can happen because he is smart enough to know it is impossible to defeat an army with just a handful of people. As they leave, he marvels at his Earth Land counterpart's insane courage.
