The king of hearts is sometimes called the “suicide king” because he appears to be sticking his sword into his head. However, it is debated whether or not the sword and hand holding it actually belong to the king, due to a different design pattern that could indicate someone else stabbed him. The king of hearts is the only one of the kings without a mustache, whereas the king of diamonds is the only king not depicted carrying a sword, wielding an axe instead giving him the card playing nickname “the man with the axe.” Additionally, the king of spades is the only king looking to the right.
The most common name for King of Hearts is Charles (presumably after Charlemagne).
