User blog:PurifyingBatter/What should my first fight be?

I have 4 fights, and I'm wondering which one should be the first. Ness vs Batter won't be an option here, as I decided to make that my Season Finale.

So what should it be?

What should be my first battle? Giygas vs Master Hand Spongebob vs Phineas King K. Rool vs Asgore
