Mysterious Alien's robe has been reproduced by CTVT. One big difference in the reproduction is the color of the material, which is a lighter purple than the original. Another is the material texture which is a bit more glossy. The final telltale sign is the collar that is attached to the robe. The original is kind of heart shaped, while the repro is straight across along the top edge. The repro is unmarked.

The only real difference between the original and the CTVT reproduction here is the texture and color of the material. Like the robe, the repro material is lighter purple and a more glossy material. It is also unmarked.

Mysterious Alien's head has been factory reproduced by Classic TV Toys. The reproduciton is a softer material and is much smaller than an original. The eyeshadow paint on the CTVT is also more pronounced. It is unmarked.
