King Claudius

King Claudius is the main antagonist from William Shakespeare's play Hamlet, and its film adaptions. He is the brother to King Hamlet, second husband to Gertrude and uncle to Hamlet. He obtained the throne of Denmark by murdering his own brother with poison and then marrying the late king's widow.

In the 1996 film version he is played by Derek Jacobi.

Trivia
Claudius is just the inspiration for Scar in The Lion King and Hades; all are brothers to a king and uncles of the main character, succeed in killing their brothers in order to take over, and try to kill their nephews, just to make sure they don't take over; however, he doesn't marry Sarabi.

He is also the inspiration for Hades. Both are brothers to a king and uncles of the main character and try to take over their home
