Prime Hiruzen/3rd Hokage. #Soloed
In my power I declare that Udon is not the biggest fodder of Naruto.
No one holds the title "Greatest fodder", but the 3rd Hoekage.
Here he is soloed, #Mangaphax
"Sexy no Justu!!"
Now before you argue this is a running gag, may I remind you the effects this had on a god?
That's blood from Naruto's punch/Justu, or she's just smilingLol
And lastly if you still think Prime Hiruzen stands a chance, take a peek at these.
A bigger pervert whom is more vulnerable to Sexy no Justu.
And just who has Udon been training with?Lol
But here's a bonus.
Naruto and his brother from another mother, too similarLol
