The Xi Gundam is the prototype mobile suit used by Hathaway Noa in Mobile Suit Gundam Hathaway, the film adaptation of Yoshiyuki Tomino's Hathaway's Flash novels that reached cinemas in 2021. Its beam rifle is one of the suit's signature weapons, and clips of its firing sound have been lifted by fans for edits, AMVs and soundboard collections. The second version in this series suggests a slightly different take or length for creators who need a cleaner firing burst. It remains useful because Gundam action edits still need a futuristic weapon sound that reads instantly as a beam attack.
