As Marty, Megs is just a shrimpy little guy. With her "Mega-Girl" shell up, thought, she becomes a young blonde bombshell, with an hourglass figure and C-cup breasts. At 5'5" and 120 lbs, she's no amazon, but she looks more mature than she actually is. Her face is reminiscent of Hillary Duff, with cornflower blue eyes and butter-yellow long, blonde hair, which she wears loose. Marty is transgender and is taking advantage of the long-effects of the PK shell to turn her real body into the likeness of Mega-Girl. It's a slow process, though, and she is a long time away from being able to have actual sex with a guy.
