A good question and a keen eye there! Basically, the version with the grey bits was my character design but when I came to draw the scenes in the comic I just felt it was a bit too complicated / busy - the grey bits made it harder to read the shape of the ribcage, I think - so I decided to simplify it a bit.
OR, let’s just say, he gave himself an upgrade 😂
A followup question from my son:
"Why does Robot 23 have grey bits on him in the picture for the order of the robots when he doesn't normally?"
Thank you! :)
