Funnily enough, Fun Pub was able to do that because the toy itself had no bio of its own.Exactly. I'm being a bit of a continuity nerd with his inclusion here. I only bought King Atlas because of that story.
There was one written, but for reasons unknown, it went completely unpublished. Had it been, it would have established King Atlas as the same character as G1 Dai Atlas, making "King Atlas" Dai Atlas's official Hasbro English name, like how Hasbro renamed Stepper "Ricochet". But of course, this didn't happen, and King Atlas became his own dude and a Cybertron character.
