According to the British magazine Nintendo Magazine System, before settling on Yoshi's Island characters for Tetris Attack, Nintendo reportedly asked Rare to replace Panel de Pon's fairies with characters from the Killer Instinct series.
Sabreman, protagonist of the Sabre Wulf series, is the inspiration for Sabrewulf in the Killer Instinct series; in Sabre Wulf, Sabreman must collect four pieces of an amulet while avoiding the titular Sabre Wulf. In Knight Lore, Sabreman must find a cure for his lycanthropy (being a werewolf).

The Sabre Wulf series was developed and published by Ultimate Play the Game; Ultimate evolved into Rare, which is known for Killer Instinct among other games.
