If Sabrina Online had voice actors:

Here's the link to the comic:

So here are my thoughts:

Mila Kunis as Sabrina


Grey Griffin as Amy and ZigZag (the one kissing Sabrina)



Owen Wilson as R.C. Racoon


Ryan Reynolds as Thomas Wolfe
   

Jenny Slate as Carli



Seth Rogen as Spike
   

Jamie Foxx as Max Black Rabbit
   

Tara Strong as Darke Katt, Tabitha, and Timmy (the one holding the ball)




Kate Micucci as Tina
   

These are some of the characters and actor/actresses that fit well (to me)
