Looks like Natsu's flames can burn away the enchantment from jACKAL. Wonder if it works on the other Tartaros demons. Wonder also if Natsu's flames might cure Laxus, since they are both dragon slayers.
Is the former council member an Exceed?
But anyway this chapter was pretty much expected, the only thing left now is for Jackal to get knocked out cold but it would be better if he doesn't go down without a last resort curse/attack like Tempesta. It would be cool if he self destructs I don't want him to get captured, Tartaros are already looking weak if Natsu captures him it would make this whole ark lame for me.
So far this arc started pretty awesome then went downhill with Natsu being immortal n all with his Friendship POWERS! I would of preferred for the plot sake, that Natsu had to decide between Lucy or Wendy. That would of made it interesting again for the sake of the Plot. I would like Natsu's character more if we knocked down, made feel like he was an ant. Then became determined to find ways to improve. Also Tartaros seems super weak. :/
