7. Alfred Is Bruce Wayne's Real Father - Batman
This one's relatively simple, if also not hugely developed as far as the finer details go. Simply, it posits that Bruce Wayne's loyal butler, Alfred, is just too faithful, protective and condescending to be just Bruce's butler, but that his overall manner suggests that, perhaps, he is also Bruce's biological father. Though it's acceptable that Alfred would become attached to Bruce given how long he has been in his service, and the bond further forged following Thomas and Martha's untimely murder, Alfred's often sarcastic attitude to Bruce better befits a disapproving father than a butler in his employ, even as familiar as they are. Of course, the reason this one isn't too developed is because nobody really wants to think about Alfred slipping one to Martha Wayne, because a) that's gross, b) it means that Bruce's mother is a massive slut and c) it completely invalidates the origin story we know and cherish. Still, Alfred would not have been
that much older than Martha at the time of...conception...and they probably would have spent a lot of time at Wayne Manor together while Thomas tended to Wayne Enterprises, so it's entirely plausible, really.
