Before Neal Adams popularized the idea that all superheroes had unbelievably idealized bodies, our beloved heroes were a little more...pear shaped. It wasn't until Ted Kord started gaining a noticeable belly during the Bwa-Ha-Ha JLI era that readers saw any kind of superhero who didn't look like he spent all his free time at the gym or mainlining steroids.
Obviously, most artists are going to continue to depict superheroes with the bodies of fitness models and porn stars, but which characters do you think would probably have far less idealized bodies?
My vote goes to Lois Lane, whose supermodel body in Tom King's wonderful Batman & Catwoman / Lois & Clark Double Date issue ruined an otherwise great joke about Lois having trouble squeezing into Selina's costume. No matter how you try to work around it, Lois Lane is the mother of a 10 year old in her late thirties (at the youngest). She is simply not going to have the same body as she did in her early twenties, let alone the kind of body you see her generally depicted as having.
Anyone else?
