With the one tribe being called Hunahpu, one such as myself would expect the opposing tribe to be called Xbalanque, the other Maya Hero Twin, but instead, they went with Coyopa. My guess as to why is that they either didn't know about Xbalanque or they thought his name was too difficult to pronounce. That being said, they still butcher Hunahpu's name if I recall correctly. If you ask me, I honestly the think Xbalanque is easier to pronounce than Hunahpu. Xbalanque is pronounced like shee-ba-lan-kay, and Hunahpu is pronounced like wa-na-pwa (if my sources are correct)
