It was developed by Tesla Leicht Institute, and is a remodeled Grungust (Type-1) that features increased armor and strength.

The transformation mechanism has been omitted since this unit is equipped with the Tronium engine which allows it to fly. It also features the Gravicon system, which is also in the Huckebein MK-II.

Although it's a prototype, it exceeds the Grungust (Type-1) series. Its nickname is "black."
