The Scepter

The Scepter, which was named Marigold by its creator, Loreman, holds the Amygdala Gem, an Infinitude Gem that influences the minds of those around it.

Loreman
Loreman is the only being that knows the truth of how the Infinitude Gems came into existence. It is unknown how the Amygdala Gem came into his possession, but soon after, he started training with it. When he was able to control the power of the gem, he forged Marigold, using it to contain and direct the power.

Colman Domingo
Marigold came into Colman's possession when he sought to learn more about the Infinitude Gems, which were considered myth by the entire universe. He met Loreman who told him the truth, but when it turned out Loreman was going to transfer his consciousness into Colman, who was being influenced by the gem. He was able to break free when The Robot One and Ganora rescued him and they killed Loreman, keeping Marigold.

Loki Ordennson
Marigold was gifted to Loki by Colman in 2012 for him to use to become king of Earth. After the failed attempt, Marigold was taken into WEAPON's custody.

WEAPON
Marigold did not stay with WEAPON for very long as it was taken by STRIKE after the events of The Muppets and ended up in the hands of Fluffy soon after.

Fluffy
Fluffy used Marigold for experiments on a number of test subjects, including the Maximoff twins, Honda and Toyota. The Amygdala Gem unleashed powers within them, turning the twins into enhanced individuals.
