As the self-perceived only legitimate son of House Senior, he considered himself the only worthy heir of his legacy (the aforementioned company). He held a deep disdain for his half brother and had severe psychological issues, ranging from paranoia as evidenced by his security measures at the company, like sealing off the bathrooms, prohibiting roof access, his "special hat" to prevent mindreading, random DNA tests and lethal robot security to name a few, which grew increasingly severe between 2020 and 2023, to intense self-loathing (likely a side effect of cheating his brother out of inheritance).
His condition worsened to the point when, in 2077, he locked down the H&H Tools Factory in outer Vegas and activated its security systems. Curiously, his body is nowhere to be found in the factory.
- He hates foreigners, Masons, carpenters, Tragic players, illegal aliens, extraterrestrials and the Flemish.
- The terminal containing his logs inside the office on the top floor of the H&H Tools Factory is actually named Anthony House's terminal, however in the last entry it is signed Alexander House.
Anthony House is only mentioned in Fallout: New Vegas.
