I'd consider the redhead on the left in the Blob karaoke scene to be Mercury over Transonic since she doesn't have the head fins. She looks so blue to me in those two panels, and I can't tell if it's my eyes playing tricks on me or not; maybe the water is "reflecting" off her metallic grey skin and altering the color slightly to me. The colors always throw me off in these wallpaper scenes and it goes back to needing some type of character bible for these things if they're going to draw specific characters. Bling! is somehow colored differently in both of those images, which isn't entirely strange considering how many different colors she's been over the years, though I most associate her with shiny purple.
