The KG-6 Sleipnir (スレイプニール Sureipunīru?) is one of the main Kataphrakts featured in the ALDNOAH.ZERO television series. It is used by the United Forces of Earth for training pilots in high school, but following Operation Earthfall it has been used on the battlefield. Despite being a training Kataphrakt, it is the signature Kataphrakt of Inaho Kaizuka.
