In Mayan mythology, Camazotz was a bat god. He was the central god of an ancient Mayan cult which may have owed its existence to giant vampire bats which are now extinct.
In the Popol Vuh, Camazotz are the bat-like monsters encountered by the Maya Hero Twins Hunahpu and Xbalanque during their trials in the underworld of Xibalba. The twins had to spend the night in the House of Bats where they squeeze themselves into their own blowguns in order to defend themselves from the circling bats. Hunahpu stuck his head out of his blowgun to see if the sun had risen and Camazotz immediately snatched off his head and carried it to the ballcourt to be hung up as the ball to be used by the gods in their next ballgame.
"An evil bat who dwelled in Xibalba in Mayan lore. When the heroic twins Xbalanque and Hunahpu went to Xibalba, he decapitated Hunahpu at the Bat House."

Bat's Solar Data is raving at the end of the 3rd Layer of the Sun, stuck reliving events shortly before his death. He will transform into Camazotz and engage the party as soon as they enter the chamber. His power and abilities are similar to his last encounter with the party.
When he gets low on HP he will use Psycho Rage and cast Zotzilaha Bane on all the party members to turn them into bats. While inflicted with Bat status, the party's overall combat ability will be reduced, especially accuracy. When a party member reverts to normal, their MP will be halved.
