Looks like Bruce Banner is getting some company in the mean green department. A She-Hulk series is coming to Disney's new streaming service, Disney+.

The news was announced at Disney's D23 Expo in Anaheim, California. While She-Hulk has been around for nearly 40 years, she's not as well-known as the Hulk, who's had his own movies, TV series, and of course a major role in the Marvel Cinematic Universe, in which he's portrayed by Mark Ruffalo. But She-Hulk packs a punch of her own, and in recent years, she's had a bit of a comic book renaissance.

Here's everything you need to know about She-Hulk.

Who is She-Hulk?
The version we're talking about here is Jennifer Walters, an extremely intelligent lawyer who gives legal aid to various Marvel superheroes. She was created by Stan Lee and artist John Buscema, making her debut in Savage She-Hulk #1 in 1980.

Disney Plus: Everything to Know About the Streaming Service

How did she get her Hulk powers?
Jennifer Walters gets shot by some henchman for a crime boss who has it out for her dad, the sheriff. She needs an emergency blood transfusion, and it just so happens that the only available donor with the right blood type is her cousin... Bruce Banner. Her brand new gamma ray-infused blood lets her Hulk out, green skin and all.

Are her powers the same as Hulk's?
Yes and no. Like her cousin, She-Hulk is super strong, super fast, super green, and heals very quickly. Unlike Bruce in the earlier MCU films, Jen retains her intelligence and emotional control when she transforms into She-Hulk, instead of turning into a giant, green, dangerous baby-monster. In more recent comics, Jen transforms permanently instead of switching back and forth.

Who's going to play She-Hulk in the series?
Marvel has yet to announce casting for the show.

Will we get to see Mark Ruffalo as Bruce Banner in She-Hulk?
We don't know yet. But we do know that Tom Hiddleston will star in the Loki series, Jeremy Renner will return for Hawkeye, and plenty more MCU stars are appearing in Marvel's Disney+ shows, so we wouldn't rule it out.

When's it coming out?
A release date has not been announced, but given everything else on Marvel's Disney+ lineup, it likely won't release until 2022, after The Falcon and the Winter Soldier, Loki, WandaVision, Hawkeye, Ms. Marvel, and Moon Knight.

Who's behind the show?
Jessica Gao, who won an Emmy for writing the Rick and Morty episode "Pickle Rick," is attached to develop and lead the writing team for the show, according to The Hollywood Reporter. Her other credits include Silicon Valley and Robot Chicken.
