How Would We Handle Characters' Origins If We Took Over Follow Ups?! (Patreon)

Thanks for the question, SCOTT SEVERIN!!!

Throwing The Question To Ya'll: What's your Take On This Question ,people?!

FULL QUESTION IS: 

If you had to utilize a character from a beloved film/tv franchise, would you change that character’s backstory enough to fit the story, going as far as coming up with a new origin altogether? Or would you keep it just like the original version when that character was first created, no matter how ridiculous it was?   

For example: if I got the opportunity to make another Monsterverse film and I had to put Mechagodzilla in that film, I would have to completely change that monster’s entire back story because you would have to keep it believable in that universe but still keep the audience invested. Because if I decided to keep Mechagodzilla’s origin where it was built by humans/alien invaders, a good portion of the audience would question why and some would probably laugh at a mechanical version of a slow, methodical lizard.   

[Btw, my version of Mechagodzilla would be a metallic-alien organism that itself onto a Monarch satellite and reads all of the information it has on Godzilla because he is Earth’s most powerful creature. It then launches itself towards Earth to the Philippine dig site where the bones of the dead Godzilla was in Godzilla (2014) and begins the form itself around the bones and absorbs nuclear radiation within the bone marrow and becomes Mechagodzilla, a cyborg who’s sole purpose is to terminate Godzilla and other powerful threats.]
