Anton Trese's two Sigbin bodyguards are named "Puti" (White) and "Bantay" (Guard). They're very common pet dog names in the Philippines, akin to "Spot" or "Rover".
The Tikbalang (also Tigbalang, Tigbalan, Tikbalan, Tigbolan, or Werehorse) is a creature of Philippine folklore said to lurk in the mountains and rainforests of the Philippines. It is a tall, bony humanoid creature with the head and hooves of a horse and disproportionately long limbs, to the point that its knees reach above its head when it squats down. In some versions, it is a transformation of an aborted fetus sent to earth from limbo.
