Selam everybody......Merhaba from Turkey.
İ think grilled chicken has the widest varieties of spice. You can do and add any flavor you like start from spicy, sweet, sour, salty, or simply garlicky.
İn İndonesia grilled chicken calls ayam bakar, also has very much variety base on bumbu/ spices uses, or base on originated.
We have ayam bakar sunda, which comes from Sunda (west Java). Or ayam bakar Padang, from Padang-west Sumatra. Or Ayam bakar Taliwang, from Lombok island and each province/ region has own typical grilled chicken (ayam bakar).
Also base on spices used, we have ayam bakar bumbu bali, ayam bakar bumbu rujak (spicy grilled chicken), ayam bakar kecap (sweet soy sauce grilled chicken-see the recipe here), ayam bakar cabe hijau (green chili grilled chicken)... and more.
