Weighted Companion Cube's Contest History

What is the Weighted Companion Cube?
Weighted Companion Cube is a "character" from Valve's Portal that is used to help solve some of the game's puzzles. In hidden rooms, one will discover that past test subjects developed emotional attachments to their Cubes. Upon reaching a certain point, one is required to incinerate the Companion Cube, after which GLaDOS informs you that you were the quickest subject to incinerate their helpless partner.

"The Enrichment Center reminds you that the Weighted Companion Cube will never threaten to stab you and, in fact, cannot speak. In the event that the Weighted Companion Cube does speak, the Enrichment Center urges you to disregard its advice." - GLaDOS

Summer 2008 Contest - Division 5, First Group

Even after L-Block's run the previous year, people weren't sure the Cube would get the same treatment - Tetris is far more well-known than Portal, and the Cube hadn't done all that well in the bonus poll in the previous contest. After GLaDOS put up 20% in her first match, though, people realized that the Cube may actually have more strength than previously thought - and sure enough, the Cube was able to put together a nice little run, highlighted by its eking out a 2nd place over a heavily-SFFed Mega Man before bowing out respectably to Cloud and Snake.

Winter 2010 Contest - Hyrule Division - 7 Seed
 * Hyrule Division Round 1 --- Defeated (10) Sandal, 38427 [78.1%] - 10775 [21.9%]
 * Hyrule Division Round 2 --- Defeated (15) The Boss, 40132 [53.8%] - 34466 [46.2%]
 * Hyrule Semifinal --- Lost to (3) Luigi, 26360 [35.16%] - 48613 [64.84%]
 * Extrapolated Strength --- 76th [20.30%]

Thanks to a return to the 1v1 format, people doubted that the Cube could put anything together. After demolishing Sandal in its first match, people thought that it might actually have some strength - but those thoughts came crashing down once it struggled to defeat The Boss. The Cube concluded its run by managing to avoid the doubling against Luigi.
