Phase 5 of the Marvel Cinematic Universe is now underway with last week's release of Ant-Man and the Wasp: Quantumania. The film not only serves as the threequel for the larger Ant-Man franchise, but the introduction of some new characters into the saga. That includes Jentorra (Katy O'Brian), the leader of the Quantum Realm's freedom fighters who plays a key role in the film's proceedings. O'Brian is no stranger to the superhero space, having played Sara Grey on The CW'sBlack Lightning, and Kimball on Marvel's Agents of S.H.I.E.L.D. While speaking to ComicBook.com's Jenna Anderson about her role in Quantumania, O'Brian outlined how these previous superhero projects helped her new role.
