Well, since he shares the same body type as Wasp, I guess he could look a bit like him, hiding his mouth.
But while I was drawing that, I decided that I’d prefer Bee to not change anything about his looks. He has such an expressive and dynamic face that, in my opinion, allows him to communicate his feelings and opinions without any words. So, if he did lose his voice, I’d hope for him to express himself with his face and gestures.
Yes, this is just an excuse for me to draw Bee making silly faces.
