That is typical of a lot of villians....they only fit in certain a milieu; The Big Bad or the Reluctant Ally. Marvel started treating Doom differently right after his first solo appearance. And we've seen that change a lot more in the post SW 2015 world. Chris Cantwell's series is more than Doom just plotting something. His current solo is a combination character study/geo-political arc. The last issue was mostly him and Kang riffing off each other while hitchhiking across America.
