The Coalus amalgamation is the first Mineralus amalgamation of all. For being the amalgamation of the most common Mineralus, it is also the weakest of them all, but it’s still capable of easily beating entities like crewmates and impostors.
Idontknow350 also made this amalgamation one of the most aggressive, to make the weakest and most foolish entities of Mineralus quickly. This doesn't mean this is the most dangerous one. It means that it’s just the one who is most likely to attack other entities.
