Tara Duncan is the main protagonist and title character of the series. She is voiced by Saffron Henderson.
Tara Duncan is a seventeen-year old girl who deals with every day life while defeating evil with her friends Sparrow and Cal. When she casts spells, her color is blue. She was born on earth, but is still a powerful spellbinder, nonetheless. She is the main character of the series. She is sporty, playing basketball and volleyball. She is the number one fangirl of Madney Speers(as stated by Cal in "Silent Siren"), but is tone deaf.
Tara is also the leader of Alpha Team, though it is not clear until Robin states that he is Cal's superior since Tara is sick. Tara is constantly trying to balance her nonspell and spellbinder life, a task that often annoys her grandmother, Isabella.
- She will appear as a guest star in Tino's Adventures of Scooby-Doo on Zombie Island and other Weekenders/Scooby-Doo crossovers.
