MsD is a Brickipedian who entered the LEGO Universe as a duck on December 25, 2010.
MsD started out as a small character in the LEGO Universe, but slowly grew in popularity due to owning many rare items, and being a good friend. Eventually, he wandered off to Ca$hland (then called Wikia) and became a LEGO Universe Wikian. He sucked at it for a long time, but eventually got the hang of it and made good edits.
He became a Minifigure after asking Wikia to shapeshift him from a duck to a Minifigure. It took 7 months, from August 2012 to February 2013, but MsD says it was worth it. He is still marked as a duck in some areas, such as MarioWikia.
Then, he entered Brickipedia, and became a trusted Brickipedian. By this time he had left the LEGO Universe. He became a patroller and a rollbacker.
After spending some time in Minecraftia, he returned to the LEGO Universe, specifically Chima. But, like everyone else, he had to wait three extra days for the land of Chima to be opened by the lazy moderators. He also resided in Brickipedia while he waited.
He currently resides in two places: Brickipedia and Chima.
