As a Clone Kid, I Don't Want to Work Hard

One day, the protagonist suddenly transmigrates into another clone of Connor. But he's a slacker, so he doesn't want to fight Superman or take on the Justice League. To make the protagonist devote himself wholeheartedly to helping him, Luthor makes up a story...

Characters include: Luthor, the "kind, long-suffering mother"; Superman, the "irresponsible playboy dad" with an S on his chest; Batman, the "seductive homewrecker"; Connor, the "sweet, naive big brother who always takes someone else's side"; Red Robin, the "scheming villain who dresses as a woman to seduce his brother"; Damian, the "haughty young lady imprisoned in a bat castle, waiting to be rescued"; little Jon, the "foolish younger brother who doesn't realize he's in love with Robin"; the uncle with an IQ problem; and Red Hood, the "faithful wife who remarried," among others...

[An aside:

The protagonist's pairing is undecided. Either way, this is a story of one misunderstanding after another.]

Theme: Mother Luthor teaches you how to make life even better.
