Dr. Gero was once one of the greatest scientific minds that the world has ever known. One day, he mysteriously disappeared. Nobody knows what happened to him (maybe someone should ask that Android 20 fellow) but he left his famous and well equipped lab behind. In the back of the lab, an Android Repair Unit can be found. Injured or damaged Androids may come here to repair themselves after losing a battle and reduce their healing time from 2 weeks to 1 week. The unit requires a 250 zeni "donation" to be made before each usage to become operational.
