MrMasaTasa is an Finnish unterganger. He uses many programs, like iMovie and two versions of Windows Movie Maker. He is known for the "Hitler plans to be an F1 driver" series, one of his first parodies. His avatar features a Minecraft wallpaper, with Hitler as the player and Fegelein as a creeper.
On April 12, 2014, MrMasaTasa created a new channel, MrFegelTasa, specifically for parodies.
In January 2015, it was noticed both channels are no longer on YouTube, thus it is assumed that he suicided those accounts.
