Stories about kaiju, or giant monsters, have been popular for decades. To the surprise of many, Gamera is almost as old as Godzilla and first appeared on  Japanese screens in 1965. A new generation will be formally introduced to the kaiju turtle exclusively on Netflix.

“In the summer of 1989, four kids in Tokyo witness the emergence of the turtle kaiju Gamera, who bravely stands up against giant human-eating monsters.”

When the Castlevania anime came to an end, the question was raised whether or not we would get a brand-new anime focused on the descendants of Trevor Belmont. Fans will be delighted to learn that the next series of Castlevania will follow the exploits of Richter Belmont, a descendant of Trevor from the late 18th century.

“The gory and gothic adventures of the Castlevania franchise continue with an exciting new setting and their highest stakes yet. A gripping story of love and loss, Nocturne marks an evolution to the original fan-favorite Castlevania Netflix Series. Featuring a never before seen origin story of Richter Belmont (gaming icon, and one of the Franchise’s most beloved characters).”
