* The reason Gamera is the FriendToAllChildren? A huge shaper of the franchise, Noriaki Yuasa, grew up in the Imperial and then Post-War eras of Japan. After experiencing trusted teachers feed him Imperial propaganda in one era and then pro-Communist propaganda in another, he realized adults were often trying to manipulate children. He wanted to give the kids a character they'd always be able to trust to protect them.
* The classic Gamera March, especially when one finds out the singers were all school children who eagerly volunteered to sing about one of their favorite characters.

! Heisei Era

* Gamera intercepting the sonic ray a Gyaos fired at a crowd of people, blocking it with his own hand.

! Reiwa Era

* The acoustic rendition of the classic Gamera March song serving as the end credit's music. Feeling like a heartfelt send off, knowing the lyrics makes it almost sound like a lullaby assuring the children that Gamera will always fight to protect them.
