A ancient AI robot that guards an equally ancient facility

This AI from my worldbuilding thing resides in a big and constantly breaking complex responsible for controlling the planet's meteorological phenomena. It's name is Precipitation Over Precipitation. This wasn't it's original chassis, but is the result of years of sloppy repairs

It's other AI peers would describe it as "agressive" and sometimes "childish".

It and it's drones are almost always busy repairing something in it's complex, due to how big and complex the place is. If someone tries to offer any kind of help, it rejects it and gets very defensive, due to it's territorial programming.
