During the events of Super Mario RPG: Legend of the Seven Stars, Mario and his party encountered the pair of villains in Smithy's Factory. Cloaker and Domino challenged the heroes to a battle and the duo proved to be formidable opponents. However, the key to their strength rested in their ability to fight as a team. As a pair, the two could offset each other's weaknesses. Domino was strong at magic attacks but physically weak, while Cloaker had high physical attack and defense but could not wield (or withstand) magic. Thus, Mario and his party focused their attacks on one of them. With one villain gone, the other would recognize his own weaknesses and retreat. If Domino was defeated first, Cloaker would be forced to retreat to his pet snake, Earth Link. Master and pet electronically fused together, hoping their combined powers would be enough to defeat Mario. Ultimately, the effort was futile and both Cloaker and Earth Link were defeated by Mario and his allies.
