Marvel Reveals 1 Major MCU Invention Was Completely Forgotten 10 Years After The Avengers Introduced It

Warning! This review contains SPOILERS for Ironheart season 1, episodes 1-3.Marvel’s Ironheart drops a major reveal about an Avengers: Age of Ultron plot point that seemingly went nowhere in the MCU. Ironheart‘s three-episode premiere establishes the first chapter in Riri Williams’ journey as a fully independent hero following her stint with the Wakandans in Black Panther: Wakanda Forever. Riri’s own series gives her the opportunity to meet other important MCU characters.

Ironheart may not feature Tony Stark or any other Avenger, but it introduces Obadiah Stane’s son Ezekiel Stane, who wishes to distance himself from his father’s dark legacy. Riri and Ezekiel form a close bond over their pᴀssion for technology, but Riri’s botched heist mission may put Ezekiel in trouble and break their friendship. Ezekiel’s best invention is a key element in Ironheart‘s plot at the end of episode 3.

Helen Cho’s Age Of Ultron Regeneration Cradle Should Have Been One Of The MCU’s Most Groundbreaking Inventions

Helen Cho’s Regeneration Technology Isn’t Mainstream In The MCU

In Avengers: Age of Ultron, the team contacts the master geneticist Dr. Helen Cho to heal Clint Barton after he suffers life-threatening injuries while fighting Hydra. Cho uses her regeneration technology to patch up Hawkeye’s wounds with biologically-identical organic tissue. Later on, Ultron used Helen Cho’s Regeneration Cradle to create a new body for himself, but the Avengers steal it back and tamper with it, giving life to Vision.

Helen Cho’s Regeneration Cradle could be capable of healing James Rhodes’ spinal injuries

Hawkeye’s healed wounds and Vision’s near-perfect vibranium body prove Helen Cho’s regeneration technology has the makings of a historic invention. If Cho and the Avengers shared this tech with the world, countless injuries and illnesses could be treated, or even eradicated altogether, all within years. Even the most delicate surgeries could be reduced to a simple pᴀss through a Regeneration Cradle.

Yet, neither Helen Cho nor the Regeneration Cradle returned in the MCU after Avengers: Age of Ultron. Marvel Studios completely ignored Cho’s groundbreaking invention as soon as Vision was created, even though it could have come in handy for several characters. The Avengers could have attempted to use Helen Cho’s regeneration technology to save Vision and Iron Man had they kept it at hand. Most notably, Helen Cho’s Regeneration Cradle could be capable of healing James Rhodes’ spinal injuries.

1 Marvel Character Could Answer What Happened To Helen Cho And Her Regeneration Cradle

Helen Cho’s Son Might Bring Her Tech Back Soon

Amadeus Cho in his human and Hulk forms.

In the source material, Helen Cho’s son, Amadeus Cho, is one of the smartest characters in the Marvel Universe. Amadeus first befriends the Hulk and later uses nanotechnology to absorb excess gamma radiation from Bruce Banner in an effort to cure him, which unexpectedly causes Amadeus to become the new, Totally Awesome Hulk. The MCU’s Amadeus Cho must be around somewhere in the MCU, yet to cross paths with Bruce Banner.

The MCU’s current focus on legacy characters provides Amadeus Cho with the opportunity to pop up in any of the MCU’s upcoming movies or shows. Naturally, Amadeus’ introduction would probably bring his mother Helen back as well. When that happens, Helen Cho could reveal why her regeneration technology never caught on, or what kept her from sharing it with the world.

Sadly, Amadeus Cho’s origin story may be a hint at the answer. In the comics, Helen Cho and her husband Philip are murdered by the genius mastermind Pythagoras Dupree, who seeks to eliminate other brilliant minds. This may have happened in the MCU some time after the events of Avengers: Age of Ultron, leading Amadeus to go on the run and Helen’s inventions to be abandoned, or even stolen.
