Ethan Morgan (portrayed by Matthew Knight) is a geeky sci-fi-loving 15-year-old who discovers that his little sister's babysitter Sarah, is a vampire.
Sarah usually aids Ethan and Benny in their quests to defeat supernatural forces and has excellent fighting skills which, combined with her superhuman strength and speed, make her a formidable opponent.
Rory is a follower instead of a leader and has a major crush on Erica and is always eager to impress her, a trend which is in line with the traditional biter-bitten relationship.
In "The Date to end All Dates- Part 2" he shows courage (or complete stupidity) being ready to face a hooded menace until he finds out the intruder is his vice-principal, only at this point does he cow down and runs.
He later displays his loyalty with Erica when he says that "if there's a fight coming I want to be here with my friends", he only avoids the battle when placed under Anastasia's powerful glamour.
In "Say You'll Be Maztak", Erica helps Sarah get their male classmates out of a spell where they were controlled by Lucia, who wanted to be reunited with her Sun King.
Jane knows about Ethan's, Benny's, Sarah's, Rory's and Erica's supernatural abilities and keeps the secret, often helping along when they are in dangerous situations.
When Ross isn't taking cookery/dancing/archery lessons with his wife, he sells insurance – which oddly enough is something people in Whitechapel seem to need a lot of.
This is shown numerous times such as in the movie when he didn't react to the news that his entire new cult was eliminated by Ethan, Benny and Sarah, and in The Date to end All Dates when he admitted he'd let "most of his old flock" get wiped out by the Lucrifractor two hundred years ago and was extremely willing to let Benny be destroyed when the would-be wizard temporarily turned against them.
Following Stern succeeding in driving out the vampire council, Ethan invites Jesse back, as he managed to defeat the original wizard Gaelon Sinisteral.
He made his first appearance in "Welcome back Dusker" where he was quickly met with Sarah's highly emotional wrath and was plunged headfirst into a trashcan by the newly fully-fledged vampire.
His Great grandfather (Gaelon Sinisteral) was a wizard who hated vampires, and attempted to wipe them out but was defeated by Reverend Horace Black (a.k.a.
He later attempts to kill Ethan in "Independence Daze" whilst wearing a Grim Reaper-esque disguise and is referred to as "some guy without a face".
Benny is put temporarily under his control, but is taken out by his own magic and the vice-principal is soon defeated by Ethan after Sarah and Jesse successfully distract him.
Ethan telepathically attacks Stern, and uses the man's own arrogance against him, causing him to absorb energy from the Lucifractor and results in a huge explosion.
Della (portrayed by Rebecca Dalton) is a normal student at Whitechapel High, who gets her heart broken after the death of her dog, Puffles.
Stephanie (portrayed by Leah Renee Cudmore (young), Susan Robertson (elder)) is an old witch, disguised as the cheerleader captain, and the antagonist of the episode, Three Cheers for Evil.
On the night of the school pep rally, Ethan and Benny are able to thwart her plan to steal the souls of the student body and Stephanie's real age is unmasked.
Hannah Price (portrayed by Kiana Madeira) is the photographer, and the leader of the yearbook committee at Whitechapel High in the episode Double Negative.
Anastasia (portrayed by Addison Holley) is first introduced in "Welcome back Dusker" as a little girl who is after Ethan and Sarah because vampires are being attacked by an ominous green mist later identified by Benny as, "The Breath of Death".
Her personality is heavily juxtaposed to her demeanor, as she is very assertive (despite being on a council where each member has an equal vote, she always takes charge and no one seems willing to go against her) and also sinister and scary, usually resorting to death threats to get things done.
Her sense of style both in her outfits and possessions (such as her choice of duffle bag in "The Date to end all Dates- Part 2") shows that despite her youthful appearance she is actually several centuries old.
Most likely she only forced Rory and Erica to flee with her as all her remaining guards were busy holding off Stern while the rest of her Council had already fled.
Lucia (portrayed by Shiva Negar) is a queen in search of her Sun King, Mr. G summons her when he digs up a crystal skull around the school.
Malcolm Bruner (portrayed by Scott Beaudin) is a Whitechapel High student whose grandfather had recently passed in the episode "Fanged and Furious".
Sunday Clovers (portrayed by Bindi Irwin) is an energetic foreign exchange student from Australia who becomes lead in the school's upcoming play, "The Rainbow Factory", where Erica is assigned as her understudy.
In "Jockenstein", Boltz is a robotic hockey player at Whitechapel High, invented by the coach to win games, taking human body parts to make him.
Serena (portrayed by Kendra Timmins) is a local singing sensation who has the voice of an angel, but in reality she's a siren; a mythical creature whose songs bring out the self-destructive worst in anyone who hears it.
Vivian Keaner (portrayed by Marsha Mason) is Rory's mother who is first seen in "Siren Song", cheering her son on at the school's talent show.
Vivian bored Benny's grandmother in the audience with stories of what Rory does, praising that he'd be a veterinarian one day, blissfully unaware that her son's recent interest in small mammals was actually due to finding them more delicious than cute.
