Stannis Baratheon of the house Stannis and the Lord Of Dragonstone, died in the last episode of the 5th season of Game of Thrones.
The king never new defeat and failure. He is a warrior at heart and his strength and strong willpower could be seen in the war against the Lannisters at the Battle of the Black Water.
This tribute video to Stannis Baratheon is so good, you will wish he never died in the series famous for killing all your favourite actors. M&M, the maker of this cool video says, he makes stupid videos in his bio, but we do not think so. :)
