Weighted Companion Square²
From threeA Wiki
Weighted Companion Square² is the first figure revealed due to the collaboration between ThreeA and Valve. This Square² variation is a play on the infamous Weighted Companion Cube from the Portal game series. While fans of 3A will already recognize the Square² character, it is likely that newcomers venturing from the Valve fan base may not understand the use of the platform.
As this humorous interpretation of the Weighted Companion Cube combines two characters of the separate companies into one unique figure, it could be viewed as a teaser to the upcoming collaboration.
