Ayyy this is cool, I'm definitely going to check out your comic OuO
The most popular cryptid here is... -sigh- the chupacabra. The whole fad in the 90's started in my hometown and way too much tax money went into trying to hunt it down. So I'm always on the fence when it comes to it-----even if I based traits on the main in my comic, ironically.
We have a few others like El Vampiro de Moca (The Moca Vampire), and this giant bird I forgot from which town, but I'm more well-versed in the Arawak/TaĂno mythology since I did a lot of research about it in my comic (which some things are basically a retelling of some myths, mainly involving the god of the dead, Makeautaurie Guayaba and Atabey)
But if you have any questions about that, I'd be happy to tell ya : D I'm honestly a cryptid/monster fan myself, so I tend to research a few, and I'm going to admit one of my favorites is the mothman |'D
