Emperor Palpatine and Cersei Lannister
The main trait that both Emperor Palpatine and Cersei Lannister have in common is that they are evil. Being that they are both evil, that leads to them being the main villain in their respected franchise.
They have no regard for anyone other than themselves, and each have done brutal things to innocent people.
For both the Emperor and Cersei, their brutality is a result of their desire for power. Palpatine is the ruler of the entire galaxy, and Cersei is at one point the Queen of the Seven Kingdoms. Both are ruthless leaders who instill fear in their people.
Cersei and the Emperor share a trait of arrogance. They have that arrogance because they believe that no one will be able to stop them, which is one of the key reasons that both characters fell in their stories.
At the same time, Game of Thrones does show a more human quality for Cersei than Star Wars does for the Emperor. Cersei cares deeply for her children as a mother, and wants the best for them. However, that struggle for continuous power leads to her eventual demise.
Emperor Palpatine and Cersei Lannister are both villains, so it makes sense that the two have a lot of traits in common.
