Kimberly Brooks is the voice actress of Allura. She has voiced for several animated TV series and video games, but has also done acting for live-action series and theater. She is best known for her voice role as Jasper from Steven Universe.
Working on Legendary Defender, it is rare for the entire cast to record at the same time, but Brooks enjoys when the recording booth is filled with as many people as possible because of the genuine bond between the series cast and staff; she compares their bond to that of forming Voltron. Brooks considers Allura to be a multi-faceted feminine, youthful, strong character and one of the best "gifts" of a role she has ever received. She believes that Allura is very intuitive and has a connection with all of the Voltron Lions because of King Alfor and growing up with the Lions, and this is why Allura believed she could pilot a Lion but only needed to focus on their bond and put it into practice. Her story resonates with Brooks as a lesson to the viewers to have confidence in their abilities and believe themselves. Outside of voice acting, she likes to stay busy doing promo work, announcing, cooking, and traveling.
