Immunity is a creature's resilience or total impervious nature to supernatural powers, objects, effects, or forces that affect other members of its species. It appears that a creature's age, power level, and/or rank within its species hierarchy dictates if it is immune to its species' weaknesses and to what degree it is immune.
Examples
Vampires
- Vampires' minds are like their reflection in a mirror; thus, they are immune to telepathic probing. However, more powerful telepaths, such as Splenden Beasts, can bypass this.
- Due to their undead bodies, vampires do not generate life force; the Root monster tried to drain life force from Angel, and killed itself in the process[1]. Non was also unable to drain life energy from Spike[2].
- Vampires are immune to the effects of werewolf bites.
- Vampires are immune in the effect produced by pheromones of certain creatures such as the She-Mantis. It was demonstrated when Claw tried to attack the She-Mantis in her human disguise: he was immediately frightened by her, implying that, unlike the human males who were smitten by her presence, pheromones either alerted vampires or (at least) made them perceive her true nature[3].
- Spike was immune to the mystical shroud that prevented humans from discovering that Glory and Ben were one and the same[4].
- As vampires grow older and more powerful, they become more resistant to weaknesses such as sunlight and holy items. The Master was able to touch a cross directly despite it burning his hand[5], and Spike bludgeoned Angel with a large cross during their fight for the Cup of Perpetual Torment[6].
Demons
- Gnarl was immune to Willow Rosenberg's magical attacks[7].
- Matango was immune to magical attacks; D'Hoffryn stole this power for himself[8]
Other
- Angel was immune to Billy Blim's power to induce misogyny in men. He later explained to Cordelia that this was because he had given up on hate a long time ago; even as Angelus, he killed out of sport or pleasure, and never felt any anger or hate towards his victims[9]. As Angelus, he was unaffected by the Judge's incinerating touch, as unlike his ensouled self, he had no humanity for the Judge to burn out[10].
