Does Wendy eat air to help her with her power? Since she's a Dragon Slayer, she needs to eat her power to help her. So, if she ate air around non-polluted areas, she could use her wind power more often than Natsu or Gajeel. As said, if she were able to perform this eating process it would be pretty amazing.

So, does Wendy eat air to help her with her power?
Yes, Carla said so (From Fairy Tail chapter 136, &quot;Coffin&quot;)


Natsu : The &quot;Sky Dragon Slayer&quot;. What does she eat?
Carla : Air
Natsu : Is it delicious?
Carla : Yes...
