@Ikki_Minami_: Black Star cuts Natsu's head off.
I doubt Atlas Flames Natsu's strongest hit can even hurt Black Star.
Black Star takes Natsu's nakama power and cuts it in half. After he is finished with Natsu he will break his back on purpose and continues to beat Natsu to a pulp.
Natsu thought that Gildarts was scary, wait till he sees Madness Release.
Black Star won't need Tsubaki, one kick will do.
