Dan: The main character.
Dan is the one who narrates. (And no, those aren't big
pupil-less eyes. He's wearing
glasses.) He's the man with the plan... quick to find his
way out of any mess. Nothing seems to rattle Dan for long.
To date, he's stopped a rampaging mutant, an alien
assassination plot, rescued a stranded alien, saved the
school from a massive explosion and invented a time
machine to get out of detention. Dan is also the honorary
Ambassador of Earth. Currently he's working on a way to
reverse the scientific accident that split him from his
fears.
Todd: Dan's cynical best friend. Todd is always
dragged into trouble. He was once eaten by a mutated
classmate, and dragged into the past. He recently
reassumed his role as Dan's sidekick and is dating
Jennifer. He went crazy for awhile and tried to hit
people with a bat.
Boffy: A talking dog that
wandered into Dan's World and decided to stay. His past
is mysterious, but probably just involved watching alot
of television and drinking out of the toilet. He likes to
read and go places where he doesn't belong. He lives in
an abandoned shed on school grounds with Visitor. His
main enemies include Mr. Parker, the librarian, and Ash,
who seems to want Boffy for his own twisted purposes.
Since coming to the strip, he's been smushed by a mutant,
consistantly tormented by Ash, given a bath, and turned
into a giant by Jeremy's Teleform Device.
Jeremy: The mad scientist of the group, who until
recently was shunned by the others. He's the creator of
the Teleform Device, an invention designed to change the
genetic structure of people and objects. It was a mishap
with this device that created Willzilla, the one-time
scorge of Dan's World. He redesigned Dan's time machine
and perfected it. Although quiet, Jeremy has proven many
times to care deeply for his friends, even at his own
expense.
Mandy: Sweet, helpful, and easily embarassed. Mandy
loves animals. (Especially Boffy.) Shy and a little
introverted, Mandy keeps to herself a lot. She started a
shaky friendship with Summer, but doesn't seem to know
how to interact well with others, besides Dan. Her and
Dan have been friends since they were children.
Dana: He's a messy conglomerate of nueroses and random
paranoia. The most traumatic event of his life was ten
years ago, when his cat was hit by a car. New traumas are
being created daily. He started seeing a therapist, but
it doesn't seem to be helping.
Gruesome: Dana's childhood
kitty who was narrowly rescued in a time travel
expedition. Gruesome is loyally devoted to Dana, and
seems to like Boffy. His only real adventure since
returning has been following Jinny around on a search for
Dan. He only speaks cat.
Jamie: The punk of the area. Jamie hates Dan with a
passion. Eh, actually he hates everybody. Not much is
known about Jamie yet, but it has been revealed that he
has a top-secret plan to eliminate Dan. (He also seems to
have some sort of grudge against Dana.)
Will: Slow-witted and quiet. He was skinny until hit
by the beam of the Teleform Device, at which point he
inherited Jeremy's fat cells. Once mutated, the fat cells
seem to have stabilized. (Even though he's permenantly
evil now.) He works for Jamie.
Chad and
Wendy: Presumably, they're in love.
I think that's what the hearts mean.
Miss Smith: She's the English and Creative Writing teacher.
Worse than any of the other teachers in Dan's school.
Smith is an incarnation of Satan. Dan once dumped mutated
fat on her head... and she'll never forget it. She also
teaches German. (But not well.)
Summer: Jamie's girlfriend, and unwitting henchperson.
It's not yet known where her true affiliation lies, but
she seems to like Dan, much to Jamie's fury. She's slowly
getting fed up with her boyfriend.
Joe: Dan's main confidante and partner in crime.
Usually seen with Toby. Joe is fun-loving, helpful and
quick to size people up. His goofy grin hides a sharp
mind. Joe is usually calm, but when someone messes with
his friends, he wants blood.
Toby: Joe's long-time friend and constant cohort.
Toby has an unquenchable sense of adventure, even despite
having his head ripped off. He's rash and quick to act.
His head was finally reconnected to his body, but with
thread that doesn't match. He never thinks his plans
through. He's also developed a bad habit of hitting on
the wrong women.
Ash: An obsessed fan-boy, currently living in the
world of Final Fantasy. In his delusional state, Ash is
well-meaning, easily angered, determined and heroic. In
real life, he's a fruitcake. His overwhelming desire is
to capture Boffy. (For reasons that change with his
current delusion.) Ash switches realities and obsessions
regularly. Previously he was a Pokemon trainer, a Sim,
and a zombie killer, a wizard, a farmer and a superhero.
Ray: Ray is completely and utterly insane. He's
perpetually confused, but exceedingly friendly. (And no,
he's not wearing glasses. Those are big, pupil-less eyes.)
He's friends with Visitor, because he enjoys being
abducted. Occasionally works as a Pokemon for Ash.
Visitor: A stranded alien who found his way into Dan's
World, and was maliciously baked into a casserole.
Visitor is an eternal optimist and has a flippant and
carefree attitude, despite being trillions of miles from
home. An on-going search is underway for his missing
spaceship. Only a few citizens know of his existance.
Boffy and Dan are his best friends. He thinks Dan is the
Ambassador of Earth. It has been revealed that he is a
political refuge from his home planet of Vuloovia, where
he was a research scientist and activist.
Jennifer: Jennifer is a quiet girl, no one really knows
much about her. She inadvertantly ate Cory, was
accidently injured by him, then killed him with a
flyswatter.
Lisa: The new girl. She's very helpful, always willing
to lend a hand even though she never seems to understand
what's going on. Lisa sewed Toby's head back on. She's
also the one who got Ash into Harry Potter. She seems to
have developed a crush on Ash.
Jinny:Jinny
is Dan's next-door neighbor. She wandered into his life
one day and took him on a quest for rabbits. She loves
animals and constantly wears cat ears. She also wants a
pet zombie for some reason.
