The Blender Dimension is a universe seemingly filled with blenders and nothing else. Due to its deadly nature, anyone who attempts to set foot inside of it is instantly killed, rendering the dimension as a whole uninhabitable and unexplorable except for any potentially native species who would already be acclimated to the harsh environment.
Rick (J-22) went on a rampage after not receiving a promotion at his workplace and feeling less than other Ricks. He stormed the Flavor Core and held Simple Rick hostage, with the demand for an untraceable portal gun. Once received, Rick (J-22) opened a portal and pushed Simple Rick through it to his death, unaware that the dimension was preset for the Blender Dimension.
