Evil shockdad AU idea: Earthspark Bumblebee returns to the space bridge park because he is depressed about continuing to go undercover. He accidentally wakes up Shockwave and the two almost have a fight, until they realize that Shockwave still doesn't have all of his systems working because of his time in stasis, and Bumblebee, unable to take down someone helpless, simply wants to leave and warn Optimus directly, but can't let Shockwave alone and escape.
Bumblebee stays with Shockwave while trying to communicate with Optimus. He doesn't answer him, so Bumblebee gets frustrated and accidentally share too much about his experience "pretending to be dead". Shockwave realizes that Bumblebee has daddy issues. Now he wants to adopt him Manipulate him to use him as a shield against autobots.
I'll probably do more of this evil shockdad AU, idk, I still don't upload the drawings that I made from the other one- (Read the tags btw)
