An Inkling Girl and Boy made a cameo appearance as a Mystery Mushroom costume.
The Inklings appear as unlockable playable fighters in Super Smash Bros. Ultimate. The initial teaser trailer for Ultimate, before its title was revealed, featured the default female and male Inklings in their designs from the original Splatoon, though they were not explicitly confirmed to be playable until Nintendo's E3 2018 presentation. Inkling can potentially be the first character unlocked in the game as the first character in Samus’s Classic Mode character unlock tree.
- Inkling appears as a playable guest character in Taiko no Tatsujin: Drum 'n' Fun!, alongside Kirby, with "Splatoon 2 Medley" also being one of the game's songs.
- Inkling is the only character to have male and female alternate costumes where both genders have the same voice actor.
