Godzilla vs. Redmoon. This movie would reuse and modify the suits from Daigoro vs. Goliath.
Erabus, whose suit seemed to come from Daigoro's mother, was the mother of a creature called Hafun, and the mate of the film's titualr entity, Redmoon. The script seemed to call for Godzilla attacking both Redmoon and Erabus.
Do you like Erabus?
