About Testament

Testament is a fictional character in the Guilty Gear franchise. They first appeared in the first game in the series, Guilty Gear, as a non-playable boss character, before later appearing in Guilty Gear X and Guilty Gear XX as a playable character. They did not appear in any other Guilty Gear games until Guilty Gear Strive. They originally appeared as an androgynous male character, before being identified as agender in Guilty Gear Strive, though an earlier interview with series creator Daisuke Ishiwatari noted that they "transcended human existence" and became agender when becoming a Gear. They were originally voiced by Takami Akkun in the first Guilty Gear, before being voiced by Katsuaki Kobayashi in Guilty Gear X and XX. For Guilty Gear Strive, they were voiced by Yū Kobayashi and Kayleigh McKee in Japanese and English respectively, the latter receiving positive reception due to being a transgender actress voicing Testament.
