Centaurian Horns are body parts consisting of bone, belonged to the Centaurian race of Outworld. They first appeared in Mortal Kombat 3. One of these horns later appeared within the Konquest mode of Mortal Kombat: Armageddon as a collectible Relic named Motaro's Horn since Motaro is too a Centaurian (Centaur). Motaro’s Horn appears again in Mortal Kombat 11 as a key Krypt item.
These ram-like horns are the well known body parts of the mighty Centaurians that are notorious throughout all of the realm of Outworld for their ferocity. It would be wise to not to get in the way of these legendary creatures, for they will charge and rampage upon anyone else like a running stampede.
