Since DD occupies the same universe, they can always draw from that.
He started out as a guy with a ray gun who robbed people and used the gun to send people to another dimension for a limited time. DD fought him, the ray gun malfunctioned and then he became Death-Stalker and then gained his death touch ability, he gained that ability because his body was out out of phase with out dimension. I think a ray gun that sends people to other dimensions is a bit outlandish for a modern DD film, I wouldn't mind some sci fi elements, but anything that over the top. Bushwacker, Mr. Hyde and Purple Man have sci fi elements to them, but they are a bit more down to Earth then some random rich guy getting his hands on a ray gun that send people to another dimension. Its all about setting the proper tone, I thought the Captain America movie had too many sci fi elements that distracted from the story.
Again Death-Stalker has a lot of set up and he is not a fan favorite like Venom is, so no one will care about the set up with him.
