Who Are The Earliest Young Justice Voice Actors Credited On IMDb?

I went straight to IMDb’s cast ordering for 'Young Justice' and looked at the people listed first — that’s the easiest way to interpret “earliest credited” in a practical sense. The names that consistently appear at the top are Jesse McCartney (Robin), Khary Payton (Aqualad), Jason Spisak (Kid Flash), Nolan North (Superboy), and Danica McKellar (Miss Martian). Those five form the central young team in the early seasons, so IMDb gives them the lead credits.

Beyond the main five, the show also features lots of recurring and guest voice talent who show up later in the cast list; some of those guests are long-time industry vets whose filmographies predate the leads, but if you want the straightforward “earliest” or top-billed voices on the 'Young Justice' IMDb page, start with Jesse, Khary, Jason, Nolan, and Danica. I always enjoy spotting the guest names after that — it’s like finding Easter eggs in the credits.

I dug into the cast list on IMDb for 'Young Justice' and focused on who comes up earliest in the credits — the top-billed voices that show up first when the show’s page is sorted by billing. That’s usually a practical way to interpret “earliest credited” when people mean the primary cast rather than guest stars or one-off appearances. The names that lead that IMDb cast list are the ones most commonly associated with the series: Jesse McCartney, Khary Payton, Jason Spisak, Nolan North, and Danica McKellar.

Jesse McCartney is the first name people tend to spot — he’s the voice of the Robin/Nightwing figure in the early seasons and gets top billing because he’s one of the central leads. Khary Payton, who voices Aqualad, is another main player and sits high in the credits for similar reasons: steady presence across episodes and seasons. Jason Spisak is usually next among the young speedster-type roles (Kid Flash/Wally West), and Nolan North is widely listed for the Superboy role. Danica McKellar rounds out that core set as miss martian. Those five names are what you’ll typically see at the top of IMDb’s full cast list for 'Young Justice', and they’re the actors the site displays before scrolling into recurring characters and guest stars.

If you scroll further down IMDb’s cast pages, you’ll find older industry veterans and guest stars who appear in fewer episodes but may have longer overall careers — folks like Kevin Conroy or veterans from the broader DC animation stable sometimes show up in guest roles across seasons. But for a straightforward read of “who’s credited earliest” on IMDb’s billing for 'Young Justice', the five I listed are the core, earliest-billed voice cast I always check first. I love how the show balanced that main quintet with a rotating cast of incredible guest voices — it’s part of why the series feels so rich and layered to rewatch.
