now you're being very semantically specific. I said more powerful, more abilities. Not just stronger or capable of dead-lifting more weight. Even side characters follow this thread. Falcon started out with just wings and two uzis, now he has a remote guided drone, and missiles that shoot from the shoulders. Bucky had a steel arm, now he has a vibranuim arm. etc.Huh how does cap getting thebsuper soilder serum and spideys suit which only provided extra legs getting stronger? Giant man is versatility did itbhwlp in the fight with ghost? And all this adds to my point none of those upgrades were ahyt against thanos so with creativity liberties they were actually significantly weaker than what they have shown to been.
Strangely Hulk, and Haweye are the only ones who stayed at their original level since the beginning. But ironically, it looks like they will both be upgraded in the next movie.
