Tony Stark’s reason for building Peter Parker the Iron Spider suit in Avengers: Infinity War has been revealed.
For one, the Iron Spider suit featured reinforced web-shooters that are able to regenerate their own web solution, which is something Peter Parker already had in play.
The seeds for the Iron Spider suit were planted after Civil War, which took into account just how powerful Parker’s Spider-Sense is, with a few upgrades.
The Iron Spider suit also features a full life support system, along with a Heads Up Display, aka HUD, in the lenses and overall armor improvements.
