Oscar was a blue budgerigar (parakeet) and Paige Matthews' pet bird that she kept in a birdcage in her loft. However, when it sensed that the Source possessed Paige's then boyfriend, Shane, he killed Oscar, engulfing it in flames with his power.
- It is unknown if Oscar served as a Familiar; the Book of Shadows stated that birds, like other animals, could be Familiars sent to guide neophyte witches. However, Katrina stated that she was watching over Paige when she came into her powers, which is why she had left the Halliwell sisters.
- Oscar is never mentioned again after he was killed by The Source.
- In Valhalley of the Dolls, Paige met a dog named Oscar, which was actually a cursed man.
