The Altered-Ego Machine is a device invented by the Alchemist. Its purpose is to suck the user's supercharged ego cloud, which converts it into a super monstrous clone of the user.
The contraption is made up of an old-style vacuum, which is attached to a glassed telephone. The vacuum part sucks the ego cloud, and the converted cloud goes through the glassed telephone part. It also seems to be mobile.
It only appeared in Leggo My Ego!.
