I'm not sure specifically as I haven't read it. But generally, it might be about a magical world where there are intense battles or onslaughts of some sort, perhaps magical creatures fighting against each other or a group of magic - users facing challenges.
A common theme is the clash of different powers. Naruto has his chakra - based ninjutsu and Skarlet has her own unique powers. Fanfictions often explore how these powers interact when the two characters meet.
Since I haven't read the 'Magic Onslaught Novel', I can't say for sure who the main characters are. But they could be young wizards or witches learning to control their magic during this onslaught.
The unique aspect of onslaught graphic novels is their antagonist. Onslaught is a very different kind of villain compared to the typical ones in graphic novels. He has a complex origin story that ties in with many well - known superheroes.
One great 'age of onslaught fanfic' could be 'The Heroes of Onslaught'. It has a really engaging plot that follows a group of underdog characters during the age of onslaught. Another one is 'Onslaught's Legacy' which delves deep into the aftermath of the events in the age of onslaught and how it shapes the future of the fictional world.
One popular Naruto and Skarlet fanfiction is 'The Unlikely Alliance'. It's a story that brings together Naruto's world of ninjas and Skarlet's unique abilities in an interesting way. The characters are well - written and their interactions are engaging.
Well, the canon status of MK comics isn't straightforward. It might be canon within certain story arcs or universes, but not across the board. Different interpretations and continuities can come into play.
