The North American box arts for Kirby games are edited to give Kirby an angry-looking scowl. According to former Nintendo of America localization director Leslie Swan and former marketing employee Krysta Yang in 2025, these edits were not intended to make Kirby look angry, but determined to fight off large, tough opponents. This change was made in an effort to help Kirby appeal to a wider audience, including tween and teen demographics who were drawn to tougher-looking characters. According to Swan, Nintendo eventually stopped marketing Kirby like this so their games could use the same artwork across all regions.
