Carter's main OC, Ace.
CarterSauce was a creator on Flipnote Hatena. He had many friends on the service, including The Ghost. Carter was an avid member of the Restoring Hatena group. He enjoyed putting his friend's OC's in his flipnotes.
Flipnotes[]
Carter joined Hatena in 2010, after a year of creating Flipnotes offline. His first Flipnote received 0 stars, and was a poorly-made stick fight called "Water VS Ground." Carter didn't delete his old Flipnotes, so if you went through all 300 of them at the time of Hatena's closing, you could see obvious improvement.
He also made appearances in The Ghost's Flipnotes, like in "The Ghost Goes To Work," and fought side-by-side with him in the Hatena's Heroes series.
