Polar is a wordless action comic that uses a minimalistic and direct style inspired by movies like Le Samurai, Tokyo Drifter and Point Blank, as well as novels like The Killer Inside Me and The Eiger Sanction. Polar is also a tribute to artists like Jim Steranko, Jose Muñoz, Alberto Breccia, Alex Toth and Frank Miller.
The main character is Black Kaiser, an international hitman born in the same titled graphic novel, published by Planeta-De-Agostini in Spain and Italy in 2010.
