Monarch

Monarch is a secret scientific organization which formed to study massive unidentified terrestrial organisms as well as to protect the world from threats that they pose. This organization was formed in response of Godzilla' emergence in 1954 that alarmed the government about existence of giant monsters all over the world, and they have studied him ever since. Later, in 1970s, the possibility of existence of other dangerous giant monsters confirmed to be true with discovery of both King Kong and a race of fearsome reptillian monsters called Skullcrawler at the Skull Island.

Monarch serves as the main protagonistic forces in the MonsterVerse franchise.

Foundation
Monarch was formed in secrecy in 1946 as a joint coalition between several governments in order to hunt and study massive unidentified terrestrial organisms. As revealed in events told in Godzilla: Awakening, the first two giant monsters they discovered are Shinomura (deadly hive-minded radioactive creature composed of many smaller composite lifeforms) and Godzilla (a natural radiation-empowered reptillian creature) where the former made his presence known in 1954. As Godzilla ultimately made his presence known and fought Shinomura, Monarch cooperated with the United States military to lure Godzilla and Shinomura to Bikini Atoll, where both were thought to be killed by the Castle Bravo nuclear bomb "test." The bomb killed Shinomura, whereas Godzilla survived and went to hiding.

Decades later, in 1981, Serizawa told his son Ishiro about his experiences and belief that Godzilla was still alive somewhere. After Ishiro's father died, he was approached by Shaw, a representative of Monarch, who offered him the opportunity to join and continue his father's work. Ishiro Serizawa readily agreed and became a member of Monarch.

Skull Island Incident
In 1973, Monarch and Landsat conducted an expedition to an island in the South Pacific called Skull Island, with William Randa, Houston Brooks, and San Lin representing the organization. At this time, the organization was nearly bankrupt in spite of managed to confirmed existence of other giant monsters aside Godzilla, namely Skullcrawlers and legendary giant ape named Kong.

After Monarch agents and Sky Devil survived encounter with Kong, they met Marlow, a man who lived among natives in Skull Island. He explained that Kong was last member of his kind, having survived the war between his species and other giant monsters called Skullcrawlers, and revealed that the teams have inadvertently attracted surviving Skullcrawlers back to surface.

After returning from Skull Island, Brooks and Lin debriefed survivors James Conrad and Mason Weaver, saying that they have become official members of Monarch. By this point, Monarch have found cave paintings depicting Godzilla, Rodan, Mothra, and King Ghidorah.
