killersoul

yea and no it seems like a convenient magic to me but just based on strength it's just so-so it can cause mass scale destruction but it's definitely not stronger than gildarts magic

it's a matter of professional matching not just strength he had magic specifically targeted at dragons

is it? it seems like a time loop because he got the system and changed things the current situation happens

I mean without his older brother yes it would be enough but given who his older brother is apparently no it's not

his clothes as a group or concept learned space magic

plus makarov probably wasn't old enough to know the talent of the first generation much less zeref

there's no way zeref is at least 400+ years old as for Mavis she also had something to do with zeref and even then she didn't fully reach that level because of her false death state

other continent you mean and it's likely that they only dare to stay on the other continent for a reason it's probably not that acnologia can't beat them he probably just doesn't know about them at all

not quite it seems more like the mc's change of the plotline due to the ability mentioned in the synopsis

a quest of conquest
