I hope so, Hawk Moth is terrible. He doesn't really do anything. After powering up a disgruntled citizen with an Akuma, he basically just fucks off into the background. He has very little character development, his personality is basically "mean and foul-tempered," and he barely even exists as a character at all so much as a plot device that keeps the story (such as it is) moving.
I hope the next villains has a personality, some flair to him, and an actual presence among other characters and the audience. Hawk Moth barely exists despite being the central character storywise. How do you even do that?
