The Phillipines has a bunch of fun mythology to work with, some ideas are:
-Fire/Grass mon based on theKapre(tree ogres that like to smoke)
-Dark/Fighting Tikbalang(horse-man demons)
-Dragon/whatever Bakunawa(dragon that eats the moon to cause eclipses),
-Dragon/Flying Olimaw(dragon that brings hurricanes)
-Ground(Rock?)/Flying Manaul(bird that started/stopped a fight between sky and sea by dropping rocks and creating land, version depends on which myth)
-Rock/Fire Bacobaco(turtle that dug into Mount Pinatubo and made a volcano)
-Ghost/Fire Bulaw(flying mountain-dwellers that carry torches made of bone)
-any kind of aswang(warning if you look these up, the descriptions for some types of aswang are very gory/body horror-esque)
