Melvi Dormentaire

Melvi Dormentaire is a homunculus created from experiments conducted on the Avaro family head by Lebreau Fermet Viralesque; hence his resemblance to Gretto Avaro. He was the intended recipient of Szilard Quates' knowledge and memories and thus bears a deep hatred for Firo Prochainezo. Replacing Carlotta, Melvi is serving as a dealer at the Runorata Family's casino party in 1935.

He is a complete immortal having the ability to 'devour' others.

At Huey's request Claire Stanfield temporarily is employed as his bodyguard in exchange for his blessing Chane and Claire's marriage. This is of great annoyance to the Gandors. During a confrontation between Melvi and the brothers Melvi attempts to devour Luck when Luck attempts to end the meeting but is stopped by Keith. Claire then prevents Keith from devouring Melvi.

Claire forces Melvi to apologise to the brothers (despite being unsure what Melvi had tried to do) and then Melvi leaves knowing he can take no further action with Claire around.

Claire refers to him as a 'shithead' and tells his brothers that after he has finished his contract with Huey he will be sure to show Melvi what hell feels like.
