Kefeinzel is the flagship of Aveh's border fleet commanded by Vanderkam. It was loaded with many large guns which were very powerful but highly inaccurate. Vanderkam had a bad habit of trying to solve his problems through overwhelming force. This philosophy led to his downfall when the Kefeinzel went up against Fei Fong Wong and his highly agile Gear Weltall. Weltall was able to use its speed to avoid most of the ship's attacks and destroy its main cannon. The cannon's destruction produced an explosion so violent that it actually dealt a fatal blow to the ship and caused it to sink into the sands of the Aveh desert.
