How it should have went
omg the nine tails is like breaking the whooole leaf village cuz some bro in a mask. Kushina was tired and maybe even dying since she just gave birth to a baby named Naruto, that's also when the mask guy stole the nine tails from her. Minato was trying his best with the mask guy but to truly win they had to get rid of the nine tails. Kushina remember that the nine tails is allergic to wood, so she threw many wooden spoons at it and when it was down she ran up with a frying pan attack and knocked him far away. The masked man left as well since kushina also frying pan'd him as well. So Kushina and Minato didn't die that day and they where able to grow naruto on there own.
the biggest difference was Kushina became a bigger hero then minato and know totally wore the pants of the family ;)
