for both its beauty and strength. Because of the distinctive coloring
of a tiger it makes for a very good tattoo. It can be done in many
styles but by far the most common depiction is the Chinese style
of tiger which it was believed to be the opposite of the dragon and
often appears alongside it.

Tikbalang:
Tikbalang or tigbalang (demon horse) is a half-man and half-horse
creature. It has a horse's head, the body of a human. It travels at
night to rape female mortals. The raped women will then give birth
to more tikbalang. They are also believed to cause travelers to lose
their way particularly in mountainous or forest areas.Tikbalangs are
very playful with people, and they usually make a person imagine
things that aren't real. Sometimes a Tikbalang will drive a person crazy
. Legends say that when rain falls while the sun is shining, a pair of
Tikbalangs are being wed. Since horses only arrived in the Philippine
archipelago during the Spanish invasion (thus, the borrowed term
'kabayo'), there is a theory that the image of a half-horse, half-man
creature was propagated by the conquistadors to keep the natives
afraid of the night.
