Here another rough doodle for my new 2021 season of SHADOW-Kaijin for Seigi no Senshi Captain-Japan. This season of kaijin is going to be a mix of one-shot monsters, mass-produced clones, recurring monsters, weapons and whatever else I can come up with since they wont have a theme to them, I'm just letting my imagination run wild with them.

• Yakaishi Aku „KWBO: Yakaishi Aku is a recurring cyborg SHADOW-member based on a zombie & a doppelganger. He is a special mutant in the organization since he has the power to mutate into other SHADOW-Kaijin, either dead-units or even brand-new ones never seen before. He is very cunning, resourceful and powerful by himself in battle.
