your father, Bowser turned into a zombie, you quickly lock him inside a cage and run fast as you can

a couple hours later, he breaks out, and goes the same direction you went, his mouth dripping with blood, as he eats and infects people, turning them into his army

"Hmm.. my son.. Stop hiding.. I know you're here.."

he eventually leaps onto you and holds you in his arms, to stop you from escaping

"Soon.. you'll help me kill Mario... and we can rule the world together. Just stop resisting.. Embrace me, embrace the darkness, I know you're evil deep down.."
