Would it be crazy to headcanon rock Brock as genes bio dad?
Rock Brock is literally the only human in the lost world so he must of came from somewhere, and he's too modern to come from Gunpowder island or Kingsland so Technopolis.He is adventurous, has a curious nature, takes risks and loves to explore.Gene is also the same but on a more sensible, logical and safer side.
Let's say Rock Brock used to be smarter than he is and yearned for adventure and exploration outside of Technopolis. He managed to escape Technopolis, leaving Gene behind. (To make things more tragic it could go a different way where him and genes mom escape together)
Once Dr.X finds out they have left and haven't returned he assumes they have died and Computer Supreme doubles up the domes security, Gene is considered an orphan(Gene would be hella young and wouldn't be able to remember any of this)
Dr.X probably orders some robots to raise gene and checks in every now and then to make sure he is safe but also grows a little jealous when he realises this young dude is growing up to be hella smart thanks to being parented by robots. So when Gene is old enough to take care of himself, those robots no longer have the task of raising Gene, and also Dr.x is scared of Gene becoming the smartest and replacing him in the future to rule over Technopolis. That's when Gene made Lenny to keep him company and have as a friend.
Meanwhile, Gene's bio mom has died in the lost world and Rock Brock was unable to save her, also suffered from a major blow to the head when he escaped whatever situation that was.
Overtime, Rock Brock does lose his smarts and albeit sanity, changing him into what he is today. He has no memory of coming from Technopolis,or genes mom or the fact Gene is his bio kid. He's in his own lost world mentally and physically.
Dr.X is also unaware that Rock Brock is Gene's bio dad as he assumes he died and rock Brock acts way too different now to be compared to the man who he once was before. And he doesn't wanna be the guy to tell Gene his parents where presumed dead or what happened,he may be jealous of Gene's smarts but he doesn't straight out hate Gene.
Whaddya think of this AU or headcanon? I've forgotten what the difference is between An AU and a headcanon but am I cooking with this or should I pack my bags and go
Side note:Deep in Rock Brocks subconscious he knows he once was a father figure hence his "cool uncle or dad like" behaviour around the super 4 or even Franz since they are younger than him but he doesn't understand where this comes from or even fully registers what he's doing.
