Serleena is one of the non-playable characters in Lego Dimensions 2: The Rise of Enoch, from the Men in Black franchise.
Serleena Xath is an extremely evil alien who will kill without mercy. She is known to insult her allies and enemies alike, constantly telling them how pathetically useless they are. With the exception of Zed because she clearly has a crush on him. She usually prefers to eat anyone who stands in her way, though killing them by other means, such as using her tentacles, tends to be favorable as well.
