Misterbun was the first user on the gallery to ever reach 400 Creations, and was afan of customs, LDD, stopmotion, and decals. He also started a club named after himself, Misterbun3546 Club.
He once teamed up with PTGLego and they offered to make animated versions of any user who requested so.
Jpt23 held a 'battle' between HDisCool and Misterbun in August 6th, 2011, over the customization of LEGO Clone Troopers.
He has switched accounts and you can now find him under the user CT-3546Customs, though he has gone quite inactive since he posted a Creation titled 'Announcement', giving a message about how LEGO.com has gone a 'little out of control', and Misterbun can now be found on Flickr.
