Two of my favourite characters ever. I always thought it would be cool if these two went head to head. Although how that might come about was less certain. Boba Fett would have no place in the Transformers universe, Earth 8162, Earth 2020 or any of the other places Death's Head has been. But Death's Head has been known to do a certain amount of dimension and time hopping on that little scooter of his. So he could conceivably appear in the Star Wars universe. And as we see in the movies robotic bounty hunters are not uncommon there. So which Star Wars environment was most associated with Fett? Cloud City! Boba got his own background so DH got top billing.
In this scenario DH goes to Bespin but arrives too late to earn the 'substantial reward' offered by the Empire for the capture of the Millennium Falcon. Ever the businessman, he decides the most logical financial move would be to 'acquire' Han Solo from Fett and claim the reward offered by Jabba the Hutt. Here we see him stalking Fett on the infamous Platform 327. Boba lies in wait, hovering beneath the platform with his jetpack. As DH approaches he swoops up and ambushes him, getting off a few pot shots. But as fans of DH know 'that armour's too strong for blasters!' Fett will likely have to try something else. My money's on the mechanoid, yes?
