But is there any point to that?
It seems like it would fit with the tone these films are going for at all, having Klaw return as some racist CGI sound monster (the idea that Klaw is still a racist colonist style mercenary as a sound monster sounds like something from the Venture Brothers cartoon).
Heck Klaw is a kinda of a meh character in the comics, he often comes across as really generic, acting like a goon for characters like the Wizard. For someone so powerful, he often seems to lack ambition or creativity. In the comics, his big claim to fame is killing Black Panther's dad and Zemo did that in the films.
I think with adapting comics to the screen, you have to pick and chose what elements work, just saying things should be this way just because that is how it was written back in 1963 is not a good way to make movies. I feel like comic book Klaw would not have fit this film series tone and could off as loud, distracting CGI, that exists to show off special effects rather then a real plot purpose.
