"It's one of the greatest honors of my life to have portrayed Shinji Ikari in Neon Genesis Evangelion for Netflix's English dub" (Tweet) – via Twitter. "What Netflix Got Right and Wrong About Its Neon Genesis Evangelion Release".
Carol Grant, in an opinion piece for Vice, wrote that Shinji being played by a trans actor made the series feel more queer, saying that "Mongillo's delivery captures the delicate interplay between the masculine and feminine aspects of Shinji's voice and personality, bringing his bodily and gendered anxieties to life".
Aja Romano of Vox wrote that it was laudable that Netflix cast a non-binary actor to play Shinji.
Noel Kirkpatrick of TV Guide praised Mongillo's portrayal of Shinji, saying they excelled at switching "between sarcasm and sadness, delight and detachment", and that they did "a better job of capturing Shinji's pre-teen voice" than Spencer. Mongillo tweeted that playing Shinji was "one of the greatest honors of my life". In 2019, Mongillo voiced the main character Shinji Ikari in the Netflix dub of the anime series Neon Genesis Evangelion, replacing Spike Spencer, who played the part in the original ADV Films dub.
