Josh Levy¹

His full name appears as Joshua Aaron Levy.

He is of robust build / overweight; he is described as "the heaviest member of the group".

She has dark brown hair, sometimes tied up in a dirty/greasy ponytail in some fan-profile versions.

He wears glasses (thick frames).

Lots of acne; blemished teenage skin appears as part of her characterization.

Their clothing: usually t-shirts with science fiction (“sci-fi”) motifs, jeans or khaki pants, sometimes a blazer/grey jacket or light jacket depending on the version.

He is young, a teenager (in the original comics) although the exact age varies depending on the story.

He is extremely passionate about science fiction (“sci-fi”), universes like Star Wars, Star Trek, etc.

He has a rather argumentative character, is a "know-it-all", does not like to be contradicted and easily gets into verbal (and sometimes physical) fights with his friend/enemy Bill Dickey.

Although he has great aspirations (he wants to be a writer/comic editor) his actual ability is considered limited by other characters/fans.

He has a dry sense of humor, cynicism, sarcasm; he can be unpleasant to others, mocking.

At the same time, he has insecurities: his social status, his weight, his acceptance within the group affect him. (He is the target of Bill's teasing, etc.)

Fanatic, obsessive: his identity revolves a lot around his science fiction fandom, collectibles, and geeky debates.

Classic science fiction: Star Wars, Star Trek, Doctor Who, Kaiju, etc.

Collecting action figures, cult objects related to sci-fi.

Science fiction films and series, alternate worlds, "what if", parallel universes.

Read, debate, demonstrate your geeky knowledge.

Perhaps the music of less conventional bands, less popular rock bands; according to fan wiki, he has "less popular" musical tastes.

That his fandom is belittled or that other non-fans ridicule him.

Losing a geeky argument or being contradicted by someone "less fandom".

Being treated as the "weak nerd" of the group.

That their geeky aspirations are ignored or rejected (their stories/comics are not accepted).

Mainstream culture that does not respect what he considers authentic fandom.

Josh Levy is one of the four members of the geek club in Evan Dorkin's novel, known as the Eltingville Club. He is assigned the role of "Secretary of Science Fiction."
We could describe him like this: a Jewish teenager (apparently), overweight, with glasses, acne, and obsessed with science fiction. He lives much of his life revolving around his fandom, collecting, and debating. He has an inflated ego (he thinks he knows a lot) and tends to use that knowledge as a weapon in arguments with his friends, especially Bill. Despite his knowledge, his projects (like writing comics) don't usually yield the results he expects. Tensions within the group and his own insecurities generate constant conflicts. The work uses him as a vehicle to satirize toxic fandoms.

He is Jewish (it appears as a fact of his identity).

He has a father named Harry Levy and a mother named Sylvia Levy.

A cousin named Nathan.

Her mother is ill (she takes strong medication and has had heart attacks).

His friends (although often “rivals”) are: Bill Dickey, Pete DiNunzio, Jerry Stokes — the other three members of the Eltingville Club.

She has a particularly conflictive relationship with Bill: they fight a lot over collections, fandoms, and leadership in the group.

With Pete and Jerry the relationship is more nuanced: Pete can annoy him but they also sometimes team up; Jerry is more average, and Josh tends to look down on Jerry.
