In the Fantastic Four 2015 movie,
Von Doom gets stuck on Planet Zero because he falls into a pit of green neural goo. He says as it is happening that the goo and the planet are alive. Then we see him next a year or two later (earth time) and he has strong telekinetic powers, among other changes. He has also gone from simply being disaffected to becoming sociopathic and hell bent on destroying the earth.
What happened to Von Doom? What did he fall in and why did it change him?

I am adding a follow up to the answer below as an edit so that I can conceal the spoiler. I would think that there would be interviews with writers and producers about this because:
a planet with no distinction between biological tissue and its physical surroundings would be a really cool selling point. The planet is a living entity. It has neural tissue that looks like green molten lava. Biological tissue blends with everything, including rocks, fire, etc. The longer an organism stays there, the more of the planet blends into them. The Four each got pieces of it because they were only there for a while. Von Doom got more of it because he was there for longer. It seems like the green neural lava bestows more of it because the Four changed the first time when it was there but did not change when it was concealed during the second visit. So we are talking about the anatomy and physiology of a living entity in the form of a planet that blends with any organism that reaches its neural tissue.
Haven't there been any interviews discussing this with writers and producers?
