Algol is a Garban soldier serving under Brighton and a minor antagonist in Chouseishin Gransazer.
Algol was summoned by Brighton and sent to kill Ran, but was foiled by Ruby, who distracted him in order for Ran to get away. He later appears when Brighton brings Ran to him. He prepares to kill her, but then Tenma appears to save Ran and battles Algol. Later, Ran goes out and tries to find Algol so he can kill her. However, Ruby interferes and stops him with help from Tarious and Lion. Algol later attacks the JSDF but is killed by the Gransazers.
