A fairly common trope in animated works, this happens when a plump character tries to make themself look strong. They'll often do this by grabbing their fat waists and pushing them up, giving them the appearance of having a Heroic Build. The fat then drops back down into place for comedic effect. If they are strong, Fat and Proud, a Big Handsome Man, or Big Beautiful Woman, or any of these, they might just flex with both their fat and muscles.
- My Hero Academia: All Might describes his superpower to be similar to this. Just like a normal human can puff their chest to look stronger, he too can redistribute his body's energy output to turn from a skinny bloke to a superhuman form. However, doing so puts heavy strain on his body, even more so after he got a lung ripped out in battle and so has had his transformational time halved.
- Happens on Ultimate Muscle when Kid Muscle finally meets his father King Muscle again at the conclusion of the training storyarc. King Muscle still looks as buff as he did in his prime (aside from having a bald patch on his head, which is odd because he didnt have hair in the first place), which is lampshaded by the other older wrestlers who complain about how easily out of shape they get these days. Then it turns out that King Muscle had just rearranged all his fat to look like muscles, which is why he wasnt moving from his badass pose, and once everything slips back into place, it turns out he's gotten a huge gut and scrawny arms in the past few decades.
- The Nightmare Before Christmas: In one part of "The Shadow Dance", a deleted short clip of Oogie Boogie dancing in silhouette, he raises up his girth for a few seconds before it drops back down.
- Bugs Bunny puffs himself up in Space Jam while introducing himself to Canon Foreigner Lola Bunny. He can't sustain this pose, and soon returns to his potato-sack body shape. Lola politely giggles at this faux machismo.
- Eduardo Perez in Despicable Me 2 decides to drink his Psycho Serum near the end, turning him into a muscular, furry purple monster. This doesn't last long, since he very quickly regains his fat a few seconds after.
- One cartoon panel from Playboy has a man at the beach notice two shapely bikini bunnies approaching, and promptly moves his rounded gut into his torso. The good news: he succeeds in attaining the classic superhero shape. The bad news: without that large gut securing the waistband, his swim trunks end up around his ankles.
- In Epic Mickey, when Oswald gets mad at Mickey after learning that he's the one responsible for creating the Shadow Blot, he lifts up his waist, puffing up his chest, and challenges him to a fight. However, his waist fat goes back down when he realizes that he's accidentally broken the giant cork sealing the Blot's bottle.
- Living Books: In Arthur's Birthday, there is a rotund man at the party store. Clicking on him causes him to turn into a superhero, complete with the Heroic Build. But then his fat quickly plops down, prompting an embarrassed look on his face.
- The Ursa Circus in Kingdom Hearts 3D: Dream Drop Distance does this if you pet it or feed it enough. It first shows off it's muscles before doing a "strongman" pose while looking comically buff. Then it's rotund body suddenly sags to the floor, giving it the appearance of a beanbag. The giant bear stands there looking sad/confused for a few seconds.
- Di-Jun Huang in Ace Attorney Investigations: Miles Edgeworth 2 is a very large, muscular man who is eventually revealed to be a much flabbier man holding himself upright. He is an impostor; the real king was murdered years ago.
- In one episode of Marsupilami, Maurice attempts to impress a female gorilla by puffing up his chest and doing a Primal Chest-Pound. When the female looks completely unimpressed, Maurice's fat drops back in disappointment.
- Scooby-Doo! and the Witch's Ghost: Both Shaggy and Scooby gain a massive amount of weight early in the film. When coming across the Hex Girls, the two try to impress them by pushing up their weight, but it immediately flops down in fear when the Girls reveal their (fake) vampire teeth.
- In the Ninja Turtles episode "Return of the Justice Force", Old Superhero Stainless Steel Steve puts on his costume and seemingly regained his Heroic Build- At which point his gut regains its normal girth.
- Family Guy had a Cut Away gag with a movie called "In-Shape Out Of Shape Guy from The 50's", which is about a tough guy character who just holds in his gut while he tries to intimidate troublemakers, but as soon as he exhales, his gut pours over his waistband.
