I've got some more.
First, in CGI.
1.) Susan Murphy A.K.A. Ginormica – (from the Monsters vs. Aliens franchise). She is a gentle giantess who's rather feminine. I think that the best way to get her to burp is to feed a store’s worth of food, then let her uncontrollably emit enormous eructations to ease her stomach, with her face reddening with each progressively louder belch.
2.) Princess Fiona - (from the Shrek franchise). Despite her royal title, Fiona defies many of the stereotypes associated with it. Even as a human, she could rip a belch louder than any man, and as an ogre, they’re magnified and probably carry the scent of rats and snails.
3.) Astrid - (from the How to Train Your Dragon franchise). She is tough-as-nails Viking girl who rides her own Dragon. She would likely be belting belches after going on a drunken binge at a tavern, putting Viking and dragon alike to shame.
This took a week to put together by the way.
4.) Mavis LeaBouve Dracula - (from the Hotel Transylvania franchise). Although she is 124 years old, the daughter of Dracula can be pretty immature at times. I can imagine her playfully engaging in a burping contest with her son, Dennis, and giggling as her belches blare akin to her vampire roars.
Second, in traditional animation.
1.) Janet Van Dyne A.K.A. Wasp - (from Avengers: Earth's Mightiest Heroes). She is a feminine fashion designer and shrinking soaring super hero member of the Avengers. If she were to burp, it would probably be some small airy ones, though she can grow giant too, so those could actually become quite powerful.
2.) Ty Lee – (from Avatar: The Last Airbender). She is another girly girl, who worked as an acrobat. Her belches would likely be accidental, maybe due to drinking too much tea.
3.) Videl – (from Dragon Ball). This is the masculine martial artist daughter of Mister Satan and partner to the Great Saiyaman. She would probably let out her burps pretty casually, maybe even smirking if she ripped a ripe one.
Third, in video games.
1.) Coco Bandicoot – (from Crash Bandicoot). She is the brainy blonde little sister to Crash Bandicoot and while generally more serious, also possesses a playful side. I bet any burps that might slip out of her would smell like wumpa fruit.
2.) Mei-Ling Zhou (周美灵) – (from Overwatch). She is a climatologist and is normally very polite. Most likely, she would let out a descent-sized eructation and apologize a lot for it, as if it shattered some windows.
And finally, in live-action.
1.) Kara Zor-El A.K.A. Kara Danvers A.K.A. Supergirl – (from Supergirl (2015)). An alien superheroine with a heart as golden as her hair and a girlish attitude. Unlike Mei, I believe that one of her Kryptonian super belches actually could shatter windows – and maybe even a building.
