Hmm biggest headcanon, Hans Full is just offscreen every time maddiman appear in every game yes. He's gonna fix him up and remove all the ultimate weapon stuff so hans can just be 100% in control of his own free will without going beserk, and also this hypothetical friendly form will actually be recruitable someday. But for now every moment the game does not show sad bab being okay and alive, he is just okay and alive offscreen. He is just resting. Madds is still workin on him to fix all the problems and lil dude is tucked into bed two metres away from the plot and this is 100% canon and nobody can prove its not. Hans gets to eat all the icecream he wants while he gets better. Maddiman dragged an old tv down to the secret lab so hans can watch cartoons all day. All the abandoned teddy bears in springdale have been scavenged from the trash and given to our many arms son to hold. And also hold he baby turtle brothers. And he dad read him bedtime story every night.
Canon. It is canon. This is how i cope!
