Iron Man’s Glowing Chest Plate Is Nanobot Housing After Iron Man 3, Not An Arc Reactor
rather of officiate as a normal bow reactor , the dresser - bit display inAvengers : Infinity Waractually house a collection of nano - particles , which permit Stark to befit - up effortlessly and in a matter of seconds , without the hassle of put together ungainly pieces of armor .

Ironheart’s Suit Is Also Powered By An Arc Reactor
phase angle 4’sBlack Panther : Wakanda Forevershowed that the Ironheart suit created by Riri Williams are similarly powered by arc reactors . Riri build her first suit on her own , a rather crude model that provided the most basic defense , firepower , and flight of steps speed , though this demonstrated the first appearance of her unique heart - shaped arc nuclear reactor . merge with Stark ’s spark nuclear reactor engineering science , Riri then cooperate with Shuri , the MCU ’s new Black Panther , using vibranium to create the Ironheart Mark II armor , which was strong enough to keep Namor ’s forces occupy .
How Else The Arc Reactor Could Appear After Iron Man’s Death
retaliator : Endgamemight have marked Tony Stark ’s net adventure as the MCU ’s Iron Man , but his bequest will live on thanks to his creative thinking and technological mind . Arc reactor technology will sure as shooting continue to be relevant to the MCU , as there are many narrative grounds why the arc reactor could become a fundamental piece of applied science again . Two of Marvel Studios ' upcoming projects are do to build on Tony Stark ’s bequest by focusing on Iron Man - adjacent bomber .
