Frankenturret

"For god's sake, you're BOXES with LEGS! It is literally your only purpose! Walking onto buttons! How can you not do the one thing you were designed for?"

- Wheatley

Franken-cubes, or cube turrets (no official name is given) are hybrids of Aperture Science Weighted Storage Cubes and Sentry Turrets made by Wheatley during the course of Portal 2. Wheatley likely designed them in lack of test subjects, so that cubes can walk on buttons themselves. However, they are shown not being able to do that.

These fixtures feature a modified version of Aperture Laboratories logo, reading "Wheatley Laboratories".
