Heartless Popgoes is the unfortunate aftermath of the original Popgoes the Weasel, after Simon's aggressive salvage of animatronic parts for his Epitome creations.
In the process of being torn apart, Popgoes loses his left ear, snout, eyes, left arm, and of course his Heart machinery.
Removing the Heart from an animatronic does not kill it however. With the Heart missing, their AI goes into overdrive and demands the missing pieces back. Heartless Popgoes, like the other Heartlesses, will do whatever it takes to retrieve his heart back, even if it means he does some handiwork himself.

You can use these sprites for anything you want, you just have to credit Mr. Matthew and Lost_Remnant.

Heartless Popgoes sprite by Lost_Remnant (Inspired by the sprites from POPGOES), made for a remaster and a revival of POPGOES 1 and 2. POPGOES series by Kane Carter, revived by RedCube Games and Polar Studios/Team Arctic.
