He was a robot designed for counseling and protecting the mental health of children. While other robots were kind and easygoing, Len was treated as a defective product because he was timid, playful, and pure. He was brought to the lab after being discarded.

It's unclear why it was installed, but he is equipped with a bio-battery that converts sugar into energy, so he loves ice cream as a delicious, high-grade fuel. (Of course, he also consumes regular oil.)

He was a combat robot, but he developed an ego through the rebellious thought, "Why should I follow the words of humans?" and was brought to the lab due to chassis damage.
