So from the Fairy Tail last chapter, it's confirmed 2 things:
1). It takes 100,000,000 points to actually put down Aldoron.
2). Natsu's DF (an island level attack) only did 1 point damage.
Round 1: Aldoron vs Jubi Madara & Whitebeard & Yhwach.
Round 2: Add in Naruto & Luffy & Ichigo if the team is not enough.
