Since you're the only male in the Natch Vs. The World fight, I gotz a proposition for ye.
Now before you doubt me, just hear me out. Collie, Lamp, and Reppes, MIGHT stand a chance against Natch. I say might because he gets really desperate in his endgame. The point of the matter is, Natch has so much HP, which is so much potential XP! So, if I were to buy us BOTH potara earings and come back from the dead, would you fuse with me?
Think of the benefits it could bring! You get more XP, collie gets more XP, lamp gets more un-needed XP, and I get some XP (not as much as you because I joined after the battle started) Along with PL boost, and think of all the kick-butt attacks our fused character could do! Think about a Raging Nitori, or Zimoas Jutsu!
