In 2012, SungWon Cho garnered attention after he sang "Let it Go" in a Goofy-like voice, alongside other impressions and original voices. He also wrote Super Mario fan fiction at the time, which is how he met Anne Marie.[1] He has voiced many characters in animations and video games which can be seen in this Visual Voiceover Reel, with a fairly extensive list posted on his Tumblr.
