being a "hero" dad is not as straightforward (bowser x luigi)
33 parts Ongoing bowser tries his best as a father. He may not be the "hero" in his story, but to his kids, he's the "hero," so when his kids go missing its his job to be the "hero" and talk to his enemy's, when they dont see anything out of the same old or have "no one new" as daisy said, so when the the wairo bros sees them entering the mushroom kingdom he has to find a way to get them back, so he has one person who would not just fob him off there's and ask his help, which is humiliating, maybe even more then going to peach or maybe even mario himself..
Luigi was always playing in his brothers shadow. He didn't mind, but.. this was his chance to do something himself.. and who wouldn't help a father whose kids have run away for no good or clear reason.. even if it's bowser.. He will have to uncover years of issues and lies and problems within the koppa Kingdoms beloved royal family... and not fall in love with the head of it all...
nothing could go wrong... right?
