Gamera's huge introduction to signal his return via helicopter pilot POV. Minutes later there's another that shows his saucer mode looks fantastic.
In the mountians, when a Gyaos is about to hit Nagamine, Yonemori, and a small boy with its sonic beam as they try to traverse a bridge, Gamera puts his arm and hand over the humans to protect them from the beam.
Gamera's final duel with Gyaos is filled with these:
Bursting out of the ground to attack Gyaos.
His resurrection at the refinery, which also counts as a call back to the Showa series, where he would literally eat fire.
