Who does Fallout's Ella Purnell play in Invincible?

Invincible, Prime Video's animated superhero show based on the comics by Robert Kirkman, is known for employing top-tier voice talent. Oscar nominee Steven Yuen as teenage superhero Mark Grayson, Emmy nominee Sandra Oh as his mother Debbie, Oscar winner J.K. Simmons as his father Omni-Man, and the list just goes on and on. The show is so good at attracting talent that up-and-coming stars like Ella Purnell even stop by for cameo roles.

Purnell already made a name for herself on the show Yellowjackets, and is winning yet more accolades as the lead character in Fallout, Prime Video's new TV show based on the video game series of the same name. She's appears briefly in the season 2 finale of Invincible as a character named Jane, an archeologist searching for her missing father. Her search takes her to the tomb of Ka-Hor, a mummy who wants to possess a human body. But it doesn't want to possess either Jane or her friend Riley, since it wants a male body. Jane and Riley both call out Ka-Hor on his sexism before Invincible flies overhead, bringing with him a sandstorm.

Jane and Riley actually do find Jane's missing father Bryant; he died trying to get into Ka-Hor's tomb back in the first season, in the fourth episode:

None of these characters — Jane, Riley, Bryant, Ka-Hor — are from the original comics. It appears that Invincible may be including them as a gag. Perhaps, once a season, someone will discover the tomb of Ka-Hor, go inside, become trapped, and then die, only for someone else to find them next season.

That said, the second season gave us a good amount of backstory on both Riley and Jane for both of them to just die unceremoniously between seasons — Riley has super-strength thanks to her grandmother — but that may be part of the joke. We'll see if any of these characters come back for Invincible season 3. We don't have an exact release date for it yet, but given that voice acting is already completed, we won't have to wait as long as we did for season 2.
