Tláloc is the god of rain in Aztec religion. He was also a deity of earthly fertility and water, worshipped as a giver of life and sustenance. This came to be due to many rituals, and sacrifices that were held in his name. He was feared, but not maliciously, for his power over hail, thunder, lightning, and even rain. He is also associated with caves, springs, and mountains, most specifically the sacred mountain where he was believed to reside. Cerro Tláloc is very important in understanding how rituals surrounding this deity played out. His followers were one of the oldest and most universal in ancient Mexico.
The Luisón is one of the seven legendary beasts of Paraguay, and is the seventh and last son of Tau and Kerana. He appeared to be a giant dog, and was said to be extremely ugly, even horrendous looking. The myth says that in a family with seven male children, the last child will become Luisón.

If you heard about the argentinian law that the seventh son born in a family is to be protected/blessed by the president this is why. The belief that the seventh son born in a family transforms in a werebeast led to some families to be fearful of the child and only with the president as godfather could the curse begone.
