The Character Anatomy (or Design) in Madness Combat consists of four main body parts; the head, body, hands, and feet.
The head is very simple to understand. The face is represented by a cross, which is a technique often used when drawing to help locate facial parts. For example, the mouth would be at the bottom, the eyes would be at the left and right points, and the forehead at the top. In more newer episodes of Madness Combat, most characters have begun wearing sunglasses or other facial equipment to help identify these points. The few characters to lack the facial cross are Mag Hank, the Auditor, the Mag Agent: V3, and the Sun.
The body consists of a neck, torso, and a waist. The neck however is sometimes shown to be a part of the head and a part of the body (See image on right). This is shown by when enemies have their heads ripped off. It could also be that, the characters do not visually have necks, just as they do not visually have arms.Characters, when wearing clothing such as shirts and jackets, is shown to extend all the way to the end of the body. This is mostly for visual appearance. In Madness Combat 6.5, Deimos is seen wearing a belt at his waist. However, Sanford is wearing camo shorts, which are buckled higher above the regular character's waist. This however again, is all for visual appearance, because Sanford's main clothing item is shorts, the waist was moved up to better represent it. The feet of Madness characters are connected directly to the body. There is no space indicating any sort of legs. Most characters, are shown performing a leaning gesture when picking up certain items that indicates kneeling, although characters do not have knees. In Madness Combat 7.5, Sanford army crawls on his stomach rather than kneeling because it is easier to be seen visually. In Madness Combat 8: Inundation, Jesus appears to fall to his knees after being shot by the Auditor. The hands of characters can be seen "floating" in mid-air. This is because there are no arms seen visually, excluding in Madness Combat 9: Aggregation and Madness Combat 10: Abrogation when Hank has a mutated arm.
It seems that the bodies and heads were just hollow and filled with blood with skin on the outside, but four examples fight this opinion: in Madness Combat 4: Apotheosis, when the zombified 1337 agent's head was sliced in half, a skull was seen with a brain and throat inside, in Madness Combat 7: Consternation, Hank rips off bits of flesh and a heart out of 2 grunts, in Madness Combat 9: Aggregation, the corpse of Jesus showed a skull and a ribcage, but the rest was just red, and finally in Incident: 110A where Jesus exposes, pulls out and destroys a mag agent's brain.
