Tony Stark’s Iron Man armors allowed him to operate as a hero even though he didn’t have any innate superpowers. The primary abilities of every Iron Man suit included flight, repulsor blasts, enhanced strength, and access to advanced weaponry. Over the years, the armor underwent many upgrades, including updating the artificial intelligence from JARVIS to FRIDAY, introducing nanotechnology, and including a remote piloting function. There’s one suit that Stark never wore, however, even though it was the most powerful armor yet.
Avengers: Endgame’s Rescue Armor Was Iron Man’s Most Powerful Suit

In almost every way, the blue Rescue armor first seen in Avengers: Endgame is stronger than Iron Man’s own suits, but it was never worn by Tony Stark. First teased during Morgan Stark’s (Lexi Rabe) introduction, which saw her wear the Rescue armor’s helmet, the armor was primarily worn by Pepper Potts (Gwyneth Paltrow), who joined her husband and superhero friends as Rescue during the Battle of Earth. We didn’t get a very good look at the full capabilities of the Rescue armor in Endgame, but Pepper did pull off some impressive feats.
As well as enhanced strength, durability, and stamina, the Rescue armor gifted Pepper Potts increased speed and agility, and the usual flight and repulsor powers that each Iron Man suit uses. However, the Rescue armor swiftly takes down one of Thanos’ ships with one energy blast, suggesting her beams are stronger than Iron Man’s, and she easily takes down a Leviathan with her powerful lasers, while Stark struggled to bring one down in The Avengers. The Rescue armor is also made from nanotechnology, has energy absorption capabilities, and could even force Thanos to his knees.
