- I don't think there are many characters you could do that with (Ant-Man is more of a special case given that it was Edgar Wright's plan & the MCU was sculpted around it to an extent). In the case of Spider-Man, they're sticking with Peter Parker with Miles Morales likely being introduced later as a means to pass the torch once the MCU Peter Parker actor's contract expires & wants out. On top of that, even with other characters of color taking the mantle of other established heroes, they may or may not be as popular as their predecessors. Take Nova for example, Richard Rider is leagues more popular than Sam Alexander (who Marvel's still trying to salvage despite the low sales of his comics & his less-than-stellar fan reception). It's one thing to introduce someone who isn't well-known, it's another to introduce someone who isn't well-liked. I'd say Kamala, but she's co-existing with Carol (but yeah, Kamala is one of the few new young heroes of color that caught on).
- With the exception of Daisy Johnson, most of Marvel's race changes were on either minor characters (Heimdal) or characters without powers (Ben Urich, Nick Fury...who was already black in the Ultimate universe). Clare Temple is sort of an odd case as, although the character of Claire Temple was originally black, she took the role that was occupied by Night Nurse (a separate character in the comics who was white).
1. We're in the B-tier of heroes at this point, ones you could switch around rather easily. (And Sam's sales aren't much lower than Rider's. You talk popularity, but that doesn't necessarily translate into sales. Nova is just a 20-40k at best.)
2. This... isn't a reason? Very few characters are predicated on their race: Captain America and Black Panther are among them. It's not different from drastically changing the back story and powerset of Scarlet Witch in Avengers, people are just focused on race for many as if it is important. If you're fine with many of the movie versions of these characters, then you're already cool with changes, race is just somehow a bridge too far.
Oh, I thought he was the archetype rich white kid who trained in martial arts.
Nah, he was rich as a kid, his dad took the whole family up, parents die, then he spends the next few years in K'un Lun. The early stories are Rand coming back to New york for revenge against the man who killed his parents, Harold Meachum (CEO of Rand Meachum). Seriously, the first four issues are his origin and beating the mercs in-between him and Meachum. Then it's him trying to figure out who actually killed the target of his revenge.
And people keep talking about K'un Lun and Danny being an outsider, but people bounced into K'un Lun all the time. Early characters featured in K'un Lun as natives? Merrin, Tucos, Conal D'hu-Tsien, and Miranda Rand-Kai (Danny's half sister). Colleen Wing is half-Japanese and her dad learned the city's martial arts from a random monk.
This is the problem with people talking about Iron Fist. All they're read is Immortal Iron Fist. I've been in the trenches.
Maybe it's because I've only seen Iron Fist in the Spider-man cartoon, but is he supposed to be 40 years old? Figured he's supposed to be a teen like Spidey
Nah, Ultimate made Power Man and Iron Fist younger.
