adam keeps having his plots stolen from him.

I'm not even joking. tbh the characterization was too little to see what they're doing with him, but it was very "just-released-from-his-cocoon" adam. but his plots? they keep giving them to other characters!

he was a pivotal and prominent character in the comic infinity gauntlet saga. not anymore.

he is directly linked with the soul gem and was the first one to appear with it in the comics. infinity stones did not exist in comic lore before adam.

his first real adventure was set on counter-earth and dealing with the high evolutionary. he stops the high evolutionary from destroying counter-earth! but he's barely a footnote in the movie and now it's going to be associated with rocket. high-evolutionary was basically adam's father figure, rather than him having a mother figure.
