Nope, he's alive. He made his first public appearance in weeks just yesterday I think. Just look in the news section of your search engine.

If Kim Jong-Un were to die, power would most likely go to his sister. It would be nice if his brother was able to take over though. He has aspirations to turn North Korea into a democracy.

The OP has seen the pictures as stated in his post. I think he's questioning whether the pictures are really Kim Jong-Un, or a body double/someone who looks like him.

I read around looking for info on what would happen if he died before his kids were old enough to take over - Not a single source mentions his sister as an option for taking over. I wonder if they don't allow female leaders?
