It’s common knowledge that fanfiction is positively lousy with gay relationships, and with an almost entirely queer cast of hopelessly attractive young adults, Marvel’s Young Avengers is grade-A shippable material. With two gay men, one lesbian, two bisexuals, and a genderfluid trickster god, the two presumed cishets are outnumbered three to one. I say presumed cishets, because it’s not as though we know everything about Kate Bishop or Tommy Shepherd, which leaves plenty of room to extrapolate.
The eponymously titled Transitions by Zethsaire on AO3 explores the idea that speedster Tommy Shepherd was assigned female at birth and is physically transitioning to male. Set in a slightly alternate version of the Marvel comics universe, it follows the relationship between Tommy Shepherd and Noh-Varr, two members of the Young Avengers, and details how Tommy’s gender identity and transition process affects both of their lives. It also deals briefly with different cultural perceptions of gender, since Noh-varr is also a Kree, and his perspective on the matter is different from the average human.
