Development of Avatar: The Last Airbender for the Hyperscan video game console is reported to have been fully completed, but ultimately scrapped due to low console sales figures near the end of the Hyperscan's short retail lifespan. The artwork for the corresponding game box and card booster packs had already been released prior to the cancellation. There are rumours that full copies of the game were printed and distributed, however no photos, screenshots or gameplay footage have emerged to date.
Nick Extreme Sports (originally named Nickelodeon Sports) was the final game announced for the Hyperscan, it was also subsequently cancelled during early development and scrapped before the release of Avatar: The Last Airbender. The only remaining evidence of the game's existence pertains to an image released of the official box art depicting SpongeBob SquarePants surfing. Being a Nickelodeon branded sports game, it is presumed that Extreme Sports would've featured comparable gameplay with similar titles on other consoles such as the PlayStation and Xbox, albeit within the Hyperscan's hardware limitations and features e.g. cards unlocking new playable characters, and power-ups.
