Alien Mefilas is said to have Alien Baltan, Alien Zarab and Kemur under his control.
Mefilas had these aliens come up to show his strength saying he’s capable of making them go on a rampage anytime if he should tell them to do so.
As they disappeared soon without doing anything, it remains unknown if these aliens were real ones or just insubstantial images Mefilas created as a bluff.
Alien Baltan (III) has the same appearance as Alien Baltan (II), not the first Baltan, just with a slight difference in color.
Alien Zarab (II) is also painted a bit differently from the first one.
Kemur (II) is the same alien as the one appearing in “Ultra Q.”
Kemur’s body looks different from the first Kemur with a different painting.
He looks better built than the first one who looked so thin as the latter was played by Satoshi (Bin) Furuya. the original Ultraman actor.
The reappearance of these three aliens as servants under Mefilas had a great impact on us kids at the time anyway.
As to the actors:
Baltan III: Hakuyoji Watanabe
Zarab II: Unknown
Kemur II: It’s said to be played by Haruo Nakajima, the original Godzilla actor, but it’s not mentioned in the book “‘MR. GODZILLA’ HARUO NAKAJIMA.”
