Interactions with the player character
Viscious will attack the Vault Dweller on sight, if he has his weapon drawn, even if he wears Cathedral robes. Otherwise, he might question the presence of the Vault Dweller in the Vault and either direct him to the Master, for a nullifier or attack him.
If not killed directly by the Vault Dweller, he is still killed when the Cathedral is destroyed.
- He has an unhealthy smoking habit, although given the longevity and resilience of mutants, the probability of him developing cancer is slim.
Viscious appears in the original Fallout.
