Although not a 3D figure, Diamond Select Toys has a mock up of Vigo’s right hand man, Janosz Poha! Janosz has never had an action figure, not like this. Without checking, I’m pretty sure Peter McNicol has been immortalized as a Minimate.
Hopefully that scaled down Vigo painting will be one of its accessory. Thanks to Instagram user wrestlingcomics2k15 we also get a better look at the Ghostbusters HQ diorama. Which bares some resemblance to Kenner Ghostbusters Firehouse.
