If you have played either of the Portal video games, then the birthday-cake-obsessed GLaDos may fill you with some fear and dread, even in LEGO form. And if you have a keen eye for part usage, then you may recognize the Iron Builders seed part, 54097 from the last round of the Iron Builder competition. Bousker uses that aircraft door along with a lot of other beautiful part usage to create the terrifying GLaDos. That ingenuity helped Bousker win over the judges and come out on top as the newest Iron Builder.

Check out Bousker’s other Iron Builder entries as well as our interview with their competitor, Tim Goddard.
