hes been using it from then

this is why i think dragon slayer magic is some sort of take over he can use lighting moves at will now

2nd generation have mixed skills, but pure/one skill generation which focuses on one substance will be stronger

so far he has only used the fire x lightning roar 1 time since they got back he has yet to use anything else related to the lightning and he did say it wasn't nearly as strong as it was before when he did use it

So?

he can still use it is my point

possibly because he's running out of lightning?
idk maybe he stored some of them inside him but not to a indefinite amount, not like when he eats fire.

I am pretty sure Laxus gave Natsu some of his lighting powers!

well laxus got his powers fromt he lacrima so its entierly possible that natsu has absorberd some of the lacrimas power

In the fight vs Master Hades...Laxus gave some power to Natsu and he said something about it being a gift to Natsu at 6:00

no shit idiot but laxus isnt a real dragonslayer hes fake his power came from a lacrmia

hrm was laxus implying he could beat master hades and the only reason he didnt was because he thought it necessary for someone who is currently part of fairy tale to beat him?

mangas really need to stop with the whole main character being the only one to defeat the boss especially when they clearly state that current allies are stronger than them~!~ fairy tale is a prime example
