Does Natsu Dragneel retain his ability to utilize some of the non-dragonfire elemental magic he eats?

Question

Does Natsu retain his ability to utilize some of the non-dragonfire elemental magic he eats?

Natsu has eaten Etherion, Black Flames, and Lightning.

Does his consumption of other magics give him a chance of possibly calling them up for use in a tough battle?

Answer 1

Natsu's consumption allows him a temporary release of other elements from what he has consumed. It is not a permanent thing. When the energy of whatever he has eaten subsides, the power washes away.
