This is Yeongdeok D.A.E.G.A.E. (aka. Data Augmented Electronic Giganteus Artificial Enforcer).
An artificially made gigantic snow crab that is paired with an AI unit implanted inside the crab. It communicates with the AI to move around. However, this unit was meant to be created as a mass produced military weapon until the project was shut down due to low funds and a lack of investors. This was the only model that was created. With help of the AI, it was able to avoid being destroyed and become a bounty hunter.
