Peter was intrigued, what if he became the symbiote itself?Despite the fact that the symbiote itself is dangerous and malevolent to a fault he decided that instead of having another presence in his head, he would be the presence in the head of his host instead.
With that he began typing, adding in special genetic codes into his new previewed self that he wanted to.
He made his new form to be immune to the classic symbiote weaknesses, such as fire, sound and electricity.
Added in is also the sustenance of living without a host, procreation, and spawn docility.
But then he thought of something, does he want to be a normal symbiote?
No.
He thought of having another participant in this merge.
Eddie Brock himself.
He added it, and he saw the preview.
The image showed the full 3D CGI form of this new being, just as vicious as Venom had been, but Peter's presence in the merge toned it down.
This new being had the power to shift from vicious to normal.
If he didn't want the teeth and tongue he could just think of it.
And the merge with Eddie brought some addition to his personality.
Peter is more dominant he made sure of that, and Eddie made the new being so much more powerful, the strength and confidence it bring could make his life more interesting.
He thought of Aunt May and MJ, thus he made MJ his human lover, and Aunt May his human caretaker.
He also made his body be able to shift into a human visage, allowing him to blend into human society and keep his alien secret from MJ and Aunt May.
