Transmigrated as the Child of Superman and Batman

A homebody was transported while watching a Justice League blockbuster. He thought he'd become a superhero, but what was with ending up as a ridiculously weak white kid? Superman and Batman want to have a child, but... how are they supposed to do that? So they adopt a boy, then argue over whose powers the kid should inherit. Clark: Obviously mine: I can fly through the skies and burrow through the earth. There's nothing I can't do. Bruce: I want my kid in a cool black suit, going with me to cocktail parties and social events. Kid: Dad, Father, cut it out. Superman and Batman: Shut up! Starting today, we're going to train you to become the world's greatest superhero, and teach you how to pick up girls, how to get into bed, and so on and so on. A story about Superman Dad and Batman Daddy taking their son around for trials, where he beats everyone under the sun. Justice League members and even the Avengers make surprise appearances _(:з)∠)_ A feel-good System leveling-up story! Apparently, when the site is busy, new chapters may not show up.
