Mortis was introduced as one of the early brawlers in Supercell's Brawl Stars, released globally in 2018, where he works as an undertaker in Mortis's Mortuary. His creature of the night catchphrase and theatrical voice acting made his lines popular outside the game, clipped and shared as WhatsApp audios and soundboard memes. The German spelling kreatur reflects how the phrase circulates in European meme communities. Players and editors still reuse the clip because Mortis remains a recognizable, fan favorite character.
