Can Domino from Marvel be killed?
Well, there obviously is the case in which no human can survive, like a Moon-size meteor hitting Earth. But it's horribly uninteresting how her power works. Like in any kind of situation, she has the top. So even for the above scenario, she probably will be on one of the spaceships that escapes the destruction of Earth. In reality, without erasing her powers, she is pretty much unkillable.
Have you read her comic?
A character named Topaz, suppressed her abilities, and threw her out a window.
