The Batsuit has been repeatedly updated in order to reflect advances in technology. Originally the costume contained no protective armor since the creative talent felt that it made Batman seem too powerful to see him shrug off bullet hits. However, the real world advent of various forms of personal protective materials like Kevlar and the realization that being shot while wearing such protection still should be avoided, has led to the costume being re-imagined with varying forms of bulletproof protection which employs the aforementioned use of the suit's chest symbol to lure shots at the armor's strongest point. Despite the armor, Batman almost always evades gunfire and is very rarely actually shot. After recovering from his spinal cord injury (the result of Bane's attack), Batman reinforced the armor with a material to dampen shocks and impact, along with a spinal brace, to protect himself from such abuse.

The Beyonder transported Spider-Man along with other heroes and villains to Battleworld to take place in the Secret Wars, an intergalactic battle between the world’s greatest heroes and villains. During the battle, Spider-Man’s suit was badly damaged and he needed a new one. Peter came upon a strange machine that produced a black substance which slithered over him and covered his entire body. This new black and white costume, similar to Arachne's costume, replaced his old costume. Once the heroes won the battle, they were all transported back to Earth and Spider-Man kept on wearing the suit because it enhanced his strength, speed, and agility. He would start experiencing odd signs of fatigue and became even more concerned when he discovered that the suit produced organic webbing. He took the suit to Reed Richards who told him that it's actually a living alien symbiote, which can only survive by bonding to a host and draining their life-force away. Reed used a sonic emitter to separate Peter from the suit. Spider-Man was now without a costume and Johnny Storm, as part of a practical joke, gave Peter an old Fantastic Four costume with a paper bag for a mask and dubbed him the Bombastic Bag-Man. Admiring the black suit's design, Spider-Man's then-girlfriend and crime-fighting partner the Black Cat made him a cloth version of the black costume which he would start using for a time. The symbiote made its way back to Peter and attempted to permanently bond with him, but Peter used the sounds of a church bell to seemingly destroy the suit. It survived and found a host in Eddie Brock to become one of Spider-Man's deadliest and most recurring foes, Venom.
