Creatures of Filipino Folklore is the main theme of the Trese. Most people are not familiar with Filipino Cryptozoology but I will be helpful in that regard. I will only focus on creatures featured in the First Season of Trese. These monsters are not yet mainstream but at a certain point, Only Haitians know what a Zombie is. The Twins, The electric creature, and the other twins won’t be in this article. They are original concepts and not a part of Filipino Folklore.
Trese is the most-watched Netflix original in the Philippines right now. Most likely, it has something to do with Filipino culture finally having representation on an international platform. You don’t need to be a Filipino to enjoy this Anime. You get to learn about Filipino folklore and culture, but Trese is Universal.
