The best part of people drawing connections between Mob and Steven is the similar messages between the two shows.
Steven literally says “if you just let everyone be whoever they are maybe you could let yourself be whoever you are too”
And one of Mob Psycho’s themes is literally “if everyone is not special maybe you can be what you want be”
Both Mob and Steven struggled with an alternate version of themselves a version people pushed him to be or pushed to provoke.
In Mob’s case the amalgamation of his powers and abilities turned into a “separate” enity, from people as close to him as Teru to members of Claw everyone has tried to get him to use that power and fight with it
For Steven it was a whole expectations, he was expected to be Pink Diamond he was expected to be Rose. His family and enemies all alike compared Steven to his mother and pressured him to be like her or to even be her
And beautifully in the end they both cone to terms with their alternate selves
