A new addition for the Fallout: Equestria creature catalog!
Protectron - Centaurion model (AKA Centaurtron). While most protectrons served as personal bodyguards or for common security enforcement, the centaurtron is a more advanced guardian created to protect Very Important Ponies and secure public areas such as banks and corporate headquarters. Remaining centaurtrons continue to follow their programming from before the Great War, protecting areas possibly full of untouched pre-war loot!

The Centaurtron stands roughly 2 ponies tall and its compartments contain a wide array of crowd-suppressing weapons - and degradation in its systems has made many of its non-lethal weapons quite deadly.
