Who Is Jentorra in Ant-Man and the Wasp: Quantumania?

Katy O'Brian, best known for her roles in Z Nation and Black Lightning, joined the Marvel Cinematic Universe with Ant-Man & the Wasp: Quantumania, which marks the live-action debut of Jentorra, the niece of Queen Jarella from planet K'ai. Created by Scott Reed in Realm of Kings: Son of Hulk #1, Jentorra has only ever appeared in a handful of comics, and by and large, is not a major player in the larger Marvel mythology (not unlike Lord Krylar, played in the film by Bill Murray). She also has ties to the Incredible Hulk and his mythology, suggesting that if She-Hulk either gets a season two, or any of those plot threads are picked up in future movies, Jentorra could return and play a bigger role. 

In Ant-Man & the Wasp: Quantumania, Jentorra leads Quaz, Xolum, and Veb, a group of freedom fighters who end up working with the Lang family against Kang and MODOK in the Quantum Realm. Her whole superhero career can be summed up in just a few sentences in the comics, but she definitely does have strong ties to the MIcroverse even on the page. That's likely what made her a strong candidate to show up in Quantumania.

As described by her Marvel Wiki entry, Jarella isn't just royalty; she is "also the trained apprentice of the Sorcerer Triad. When her planet was attacked by the Psyklop, she used her magic to try to summon the Hulk, who had saved their world before and been in love with her aunt. Unexpectedly, she summoned a different, far more monstrous Hulk – Hiro-Kala, the Hulk's son. She attempted to stop Hiro Kala's destruction, only to be defeated. He took K'ai with him out of the Microverse, leaving Jentorra floating in space. She was picked up by Arcturus Rann and became part of his Enigma Force, a team to defeat Hiro and return K'ai to the Microverse."
