Rex (Fallout: New Vegas)

Rex (full designation of Cyber-Hound Mk. III, LEO Support Model, Serial Number B955883) is a 209 year old cyberdog living in Freeside in 2281. He is owned by the King. He doesn't like hats, or people who wear them.

Background
Rex is a cybernetic dog that has been around since pre-war times. He was used by the Denver Police Department and Caesar’s Legion before being mostly blown up during the Battle of Hoover Dam. Since then, he's been the loyal pet of The King of The Kings in Freeside. Capable of sniffing out loot and taking a large amount of punishment, he only has one (big) problem: his brain is starting to deteriorate.

Interactions with the player character
A high-tech Dogmeat, Rex provides the Search and Mark perk while he's in your entourage.
