In the launch version of Nickelodeon All-Star Brawl 2, GIR's voice lines were not artificially pitched up as they were in the Invader Zim series, making it sound as if they had got a very poor replacement actor to those not familiar with how GIR's voice was originally made. GIR's voice actor Rosearik Rikki Simons pointed this out on Twitter, and it would be resolved in a latter update. However, the updated GIR voice lines still don't have the digitizer voice filter he had in the original series.
