Riri Williams Flew Too High With Her First Armor… Like Iron Man

Although Lily She had flown in her Ironheart suit before having to flee the FBI with Shuri and Okoye, who overestimated the suit's capacity. Lily's suit at that moment was incomplete, but functional, just flawed, and not all of the features worked. Nonetheless, Riri flies too high during the chase, starving her and the spacesuit of oxygen, damaging the suit and causing Riri to free-fall, with potentially fatal consequences. Riri survives the horrific moment, but the suit is no longer wearable, reflecting a mistake Iron Man made when testing his Mark II suit.
In the first Iron Man movie, Tony Stark is testing his new Mark II armor, which proves successful before he tests its height limit.

While Tony's superhero transformation was the result of a traumatic experience, Lily's transformation came from an interest in helping others, and she displayed a much higher emotional intelligence than Tony Stark. Riri is a genius, but she's still learning, and early mistakes like this will ensure she'll be more careful and upgrade the suit a few times, showing that while she made the same mistakes as Iron Man, she doesn't have to repeat all of his mistakes And become a copy of him to be a hero.
