Life Before the Apocalypse
Before the anime apocalypse, Alan lived in the suburbs of Queens, New York. He went to an unnamed school there, where he was constantly bullied by people who knew him as a "weeb". His only friend was Jacob Hogan, who didn't care about anime as much as Alan did, but they were still friends anyway.
As a human, Alan was a brown-haired, lean teenager wearing square glasses. In Act I of the Pilot, he wears a red shirt and blue jeans at his school.
From Act II of the Pilot on-wards, Alan grew grey wolf ears, claws, and fangs. He no longer needed to wear glasses, so he didn't.
Alan, both while human and hanyo, was a timid creature.
