Songbird/Screaming Mimi (Thunderbolts vs Masters of Evil)
From what I understand, the shift between Thunderbolts and Masters of Evil is supposed to be an illusion, a cosmetic hologram of sorts.
In that case, why did Screaming Mimi's powers start doing things Screaming Mimi couldn't do, such as turning into physical bands of sonic energy, or becoming more directed and focused? It seemed she could only do this as Songbird, whereas Screaming Mimi just had more of a Black Canary type of power. But if the change was supposed to be cosmetic-only, then how did her powers change, too?
