These are items from three separate brands (not counting the ones behind Luthor).
Superman is a 6-inch figure from Spin Master and Luthor is from Mattel’s Total Heroes line. Meanwhile, the Phantom Zone projector is from the Mezco One:12 Superman.
Amazing how Luthor, even with the armor, is much larger and taller in a supposedly 6-inch scale line.
Anyway, just playing around with the collection.
