We're all going to the world's fair with two back to back Gamera vs. features. Gamera must protect the children against his two newest adversaries. In Gamera vs. Jiger we celebrate the retro-futurism of Osaka's Expo '70, while Jiger presents a Swiss army knife approach to Kaiju designs: they give her all the abilities and see what sticks. In the immediate aftermath, Gamera vs. Zigra is released, wherein the friend of all children tests his metal in a monster melee with the goblin shark alien. How do these efforts rank in our scientific study of all Kaiju pictures? Stay tuned and find out.
