During the final fight between 2015's Fantastic Four and Victor Von Doom on Planet Zero Victor achieves to impede all of the Four's attacks. His primary way of doing so seems to be to suffocate them with the rock material of Planet Zero itself, which he can control with his powers. This is how he buries Ben, extinguishes Johnny's fire and holds back Sue in her "forcefield bubble", if I remember correctly.
However, with Reed he merely seems to somehow paralyze him by pressing him to the ground or making his limbs immovable. It nearly seemed as if he made Reed lose control of his very own stretching power. What did Victor actually do to Reed there? Can he even control Reed's power somehow or his very body functions (we certainly saw him somehow "overheat" people earlier)? Or did he just press him to the ground by some external force inherent to Planet Zero or his energy controlling abilities?
