The Palpatine Bros. are the brothers/clones of Sheev Palpatine, aka. Darth Sidious.
All of the bros helped Michael Rosen form The Rosen Meme Empire in the 1970's. They also attempted to kill Harrybo, Cheese, The Angry Video Game Nerd, DashieXP, Robbie Rotten, and Jack Black in Tokyo when they tried to overthrow Michael. Later, they joined up with Tulips to take down the rebels, and forced them into another dimension.

The red Shiv Palpatine loves spinning, as it's a good trick. He attacked the rebels while they were in a car, but got put in a net by Robbie and was put in jail.
Later, in 2018, Shiv helped Michael Rosen defeat a crazed Tulips, who had consumed a plank of Skywood, giving him superpowers.

The yellow Shave Palpatine is the master of screech, earraping his opponents. He attacked the rebels on a plane, but got blasted by the Angry Video Game Nerd.
