Mazinkaizer SKL (マジンカイザースカル Majinkaizā Sukaru?) is a Japanese OVA that branches off from Go Nagai’s Mazinkaiser, which itself is a derivative of Mazinger Z. The debut episode was both released and premiered on November 27, 2010. The series has been adapted into a novel, serialized in ASCII Media Works’ Dengeki Hobby Magazine, and a manga version available in the mobile phone magazine Shu 2 Comic Gekkin. Similar to Shin Mazinger Shougeki! Z Hen, this series features characters and nods to other creations by Go Nagai.
