Sawtooth Waves (previously known as The Brony Notion) is a reformed changeling, though they usually take the form of an earth pony. They have a shady orange mane with grey coat and indigo eyes.
Sawtooth defected from the changeling ranks after the attack on Canterlot, and has since spent their time in Ponyville. In 2013, they found a dimensional rift to the internet and started a YouTube channel to share their thoughts about Equestria. Along with theories and analysis, Sawtooth also posts remixes and original songs. They one day hope to overthrow the monarchy and become the democratically elected leader of Equestria.
