Frankenturret
The half weighted cube half turret creation made by Wheatley in the game Portal 2. After taking control of the facility, Wheatley begins his own testing. Since Chell and Potato GlaDos (aka PotaDos) are on the run and unavailable to use as test subjects, Wheatley must resort to creating his own. So he stuck turrets in cubes so the they could walk by themselves right onto the buttons.
"For god's sake you're boxes with legs! It's literally your only purpose!" -said by Wheatley when frustrated with the frankenturrets.
