A few adjustments were made to the design of the baby in order to project a more robotic aesthetic. Preliminary concepts for the baby, included a chainsaw that was attached to the body after it was conceived. In this new design the weapon is implemented within its design, creating a more streamlined character.

Changes to the storyboard involve the baby becoming damaged as a result of gunfire. The fourth concept is an idea of what it would look like.

The '6' tattoo on the skull is also replaced with hair of similar shape. This is subject to change in accordance to how it looks after it's transition to 3D.
