Masato Kusaka/Paradise Lost

In an alternate story where Smart Brain and the Orphnochs won, Masato Kusaka (草加 雅人) was the main user of Kamen Rider Kaixa (仮面ライダーカイザ) who was a fighter for the Human Liberation Army before being killed by the Lion Orphnoch.

Paradise Lost
In the alternate reality movie Kamen Rider 555: Paradise Lost, Masato was killed by Leo. Keitaro Kikuchi briefly wore the Kaixa Gear by drinking the experimental transformation elixir, 'Transform 1-Shot' (変身一発) and killed the Lion Orphnoch. Due to the elixir, Keitaro was unharmed. However, when the formula ran out, the Kaixa Gear disintegrated instead.
