tearing. In addition, the suit also contains various defense and protection mechanisms layered into the suit's fabric. These protective layers in the Batsuit are necessary since Batman, although strong, powerful, and intelligent, is still a human being with no inherent superhuman powers. The basic version of the Batsuit is insulated against electricity and is mildly fire resistant. Batman utilizes many different body armor designs, some of which are constructed into his Batsuits, and others which are separate. In its most basic version, the suit is bulletproof around the upper torso and back. Other versions are entirely bulletproof to small arms fire, and have advanced flexible armor plating. In the video game, Batman: Arkham Asylum Batman wears a basic batsuit throughout the game but can unlock a new "Armored" batsuit after completing the main story-line. The armored suit is much bulkier and features heavy plate armor on the torso and limbs and segmented armor on the joints and neck. Cape As different artists have taken over the responsibility of drawing the costume, the details of the suit have changed considerably. The original incarnation of the cape was a wing-like structure that may have been inspired by drawings by Leonardo da Vinci. This eventually evolved into a more cape-like design of varying length with scalloped edges to resemble the wings of a bat. The material of the cape has varied with different writers, sometimes being depicted as bulletproof and fire resistant, and other times being made of simple fabric that tears easily and is continuously replaced. For example, in the Batman: The Animated Series episode "Robin's Reckoning", Batman fell through a floor heavily compromised by machine-gun fire and landed badly, hurting his leg. He ripped up his cape and used some pieces of broken wood to make an impromptu ankle splint. He is also commonly seen with the cape able to wrap around his entire body, usually whenever he is standing or sometimes when walking. The cape may also incorporate Nomex fire-resistant/retardant material (as demonstrated in the film Batman Forever and the Knightfall novelization by Denny O'Neil) and a Kevlar weave to slow the impact of bullets. In The Dark Knight Strikes Again, the ends of the cape contained razor-sharp blades which Batman used to slice through several corrupt government officials. Batman's usage of the cape as a mode of transportation differed over the years. A hang-glider version of this concept was
