The Adventures of Jimmy Neutron: Boy Genius

Show Synopsis
The show is about Jimmy Neutron, a 12-year-old boy genius who gets in and out of trouble by inventing extraordinary gadgets and fighting evil enemies along the way. His main catchphrase seems to be "Brain Blast!", which usually comes after Jimmy comes up with an idea, accompanied by a visual of the activity in his brain. He's often joined by his best friends; Goddard, Carl Wheezer, Sheen Estevez, Cindy Vortex, Libby Folfax and Nick Dean. Together, these seven friends make up Team Neutron and will always be off on a new and fun adventure whether it's discovering something about history or fighting evil villains.

Episodes With Burps
Libby Folfax (Crystal Scales) burps in "The League of Villains" after accidentally ingesting the wrong N-Men packet. She immediately realizes that the packets were mixed up, thanks to Carl's incompetence, as she ended up with the superpower of his N-Men alias: "Burp Boy". This makes her gain the ability to unleash gigantic supersonic-blast belches, which release shock waves of concussive force from her mouth that are powerful enough to make anyone go flying. Although there are no known counter parts, Libby's ability could be compared to famous superheroes, such as Black Canary, Banshee and  Black Bolt, the Leader of the Inhumans (a group made popular in the Fantastic Four Comics) in the sense that she originally can not control her ability completely. Although this can be an arguable comparison because Black Bolt is capable of far more than just a Sonic Scream. Initially, she was understandably embarrassed by her new ability and couldn't control her burping at first. However, she adjusts to and masters becoming "Burp Girl" really quickly, to the point where she manages to become more skilled at using her sonic-blast burps than Carl was in "The N-Men", as she can burp on-cue instead of needing to drink seltzer or shake herself around to "charge up" first. Eventually, she invents a new dance  out of her burps.
