Killed Ice.. ah yes, he can kill all living things and the world they're staying at would just be another desolate floating rock.
"I'm sure I could kill her clothes"
well, sure.. even inorganic things can be killed now.
forget about desolate floating rocks in the solar system, it'll just be a dust cloud.
So that's why the robot was afraid.. even if it was not a living entity, it would just poof hahahha
@Niralam
He pretty much could, that's why even the guardian spirit is afraid of him, considering that a spirit is not even a living being.
But I don't think the concept of time, gravity and causality have any sort of definition for death.. time may stop permanently (or it will create a spatial rift), gravity or the magnetic force will drop to 0 in an area and cause a vacuum or for the case of causality, the effect would be discontinued?
