 Toho Company Ltd., the makers of Godzilla, was going to sue Japan  Radio Pictures, as they thought Agon looked too much like their  famous monster. But when they found that director/writer/SPFX  director Fuminori Ohashi (qv) (who helped out in making the first  Godzilla suit) was working on the show, Toho simply said, "Oh, its  you! Well, its okay then!"
