Wonder Woman is a superheroine in the DC Comics universe, created by William Moulton Marston in 1941, who is recognized as a feminist icon for her fights for peace, love, justice and equality.
The Cosmic Fun-House (Justice League of America #7, 1961)
With Aquaman, Superman and Batman busy, Green Arrow, The Flash, Wonder Woman and Green Lantern are imprisoned through "energy-sapping spirals" by inhabitants of the planet Angellax, who have placed a Cosmic Fun-House onto Earth. Eventually Green Arrow manages to free them, but their only escape is through the fun-house, where they change shape, most notably Wonder Woman, who has grown fat, though less realistically so in the following two pages.
The Mirage Mirrors (#130, 1962)
Similar to the last story, Wonder Woman becomes as fat as a circus lady after using the Mirage Mirrors she borrowed from Queen Hippolyte at the Charity Carnival, to play a trick on Steve Trevor, a man who cannot tell the difference between her and her secret identity Diana Prince. This shape especially comes in handy when she rolls into a ball to knock down a steam train used by Angle Man and his henchmen in a robbery scheme.
