The Robo-Rat is the third boss in Super Battletaods, who is controlled by Scuzz to rid off the Battletoads. As the toads engage in battle against Scuzz' robot, the Dark Queen watches the battle in a holographic form, and laughs or taunts the toads every time the robot attacks them. After the Robo-Rat gets destroyed, the Dark Queen's hologram vanishes into nothingness, ending level 3.
His arsenal includes twin energy ring beam guns,able to shoot lasers from his very eyes, internal air conditioner, piston kicks, belt o' grenades and a nice little rat named Scuzz inside.
These are the four phases of the Robo-Rat.
