Brainwalker

The Brainwalker (ブレインウォーカー), sometimes spelled Brain Walker, is an enemy character from the 2014 Strider, appearing initially as a mini-boss encounter and later as a recurring stage enemy.

The Brainwalker is a large walking turret, a complete weapon system designed by Professor Schlange as part of the "ZAIN Project v2", created in his pursuit of the "perfect" warrior. As an upgrade of the project's initial version, the Brainwalker's decision-making is driven internally by using a human brain[1], harvested from the citizens captured while attempting to escape Kazakh City. As the brain loses the person's sense of "purpose", the Brainwalker is forced into fighting out of pure instincts. The end result is a four-legged cybernetic organism with a large brain and a singular focus on offense.
