WindBreaker
Wind Breaker is a chubby, gassy pegasi from Cloudsdale with a particularly gross talent. If his cutie mark of a green gas cloud and name wasn't obvous, he has overactive bowels and powerful farts. He's always loaded and can fart on command but if he lets it build up and unleashes it in one foul burst he can create the gassy version of Sonic Rainbooms and travel at supersonic speeds.
In fact he reached the Nexus by traveling at speeds even Rainbow Dash had never reached and managed to break through the barrier between the Nexus and Equestria. He's now stuck here and learning how to survive in this vore obsessed world.
