I don't blame you for getting the colors wrong. I had a feeling it was him. That is a nice color scheme anyway. I think I will add that as option #2. He is a 4th wall character, so I you decide to change his colors later, he will likely try to hand wave it. Thanks for the cameo!
Edit: also, I haven't actually seen what he looks like with the proper color swaps anyway, so I don't know if I like the "official" color scheme yet anyway.
Edit 2: Here is the character link if you guys want it: https://developingspace.miraheze.org/wiki/Cameo/Guest_Info
You might be able to fit the "Please don't kill me" underneath Volt's bubble in the last pane the same way you slipped the "Oh my god Volt" into the 3rd panel.
