The OR14 "Idina" line of security robot was a specifically designed omnic unit that existed pre-Omnic Crisis. It would later become a frontline combatant specifically designed to fight against humanity during the Crisis. In addition to its great strength and superior (by human standards) agility, it was equipped with a pair of arm-mounted cannons, and an energy sword.
The OR14 was a line of omnic built in Nigeria's massive manufacturing omnium. It later became a frontline combatant during the Omnic Crisis. At the end of the war, the OR14 along with many other omnic models were taken out of production. Twenty years after the end of the conflict, the citizens of Numbani developed a more advanced version of the OR14, the OR15, to protect themselves from threats against Numbani and more importantly, Doomfist.
The Null Sector variant was apparently didn't equipped with the energy sword, but instead they are equipped with a barrier-deploying device.
