Marcus was a very prominent person who lived in ancient Michina.
He once worked for Damos before he betrayed him. He was the mastermind behind the whole plot to betray Arceus. He is the main antagonist in Arceus and the Jewel of Life. Marcus was a sly and evil person, and many people followed his orders. Marcus believed that the people of Michina should keep the Jewel of Life, or otherwise the land would return to its desolation again. Due to his belief of Michina becoming a wasteland again if the Jewel was reclaimed, a seed of selfishness and greed grew in him, like a poison.
Marcus had no intention of returning the Jewel back to Arceus when it returned. Marcus told Bronzong to use Hypnosis on Damos, and made it look like he betrayed Arceus. Arceus was upset, and Damos and Marcus fell to their death.
When Sheena arrived with Ash and his friends from the future, Marcus put Ash and his friends in prison with Damos. He pretended to be the good guy and questioned Sheena about the future. This time when Arceus appeared to get the Jewel back, Marcus gave Sheena the scepter that held the Jewel. When she opened it in front of Arceus, he was gone.
Since Marcus knew about the future, he was ready for Arceus, so he got all the Pokémon to use Shock Wave on it while they dropped Silver Water on it. Ash and his friends were able to stop Marcus, and this time only because Marcus fell to his death and his crown was left on the edge of a cliff.
Fortunately, the fall did not kill him, as it was revealed that Marcus had went on to work for Damos in the end credits.
|Heatran, like Bronzong, was also forced to obey Marcus against its will by special armor. Heatran was also very powerful and also, like all Heatran, had the ability to walk on walls and ceilings with ease. Heatran was forced to battle against Ash and Dawn, but eventually realized what it was doing thanks to Damos and Sheena, and it allowed Pikachu to destroy its armor with Iorn Tail. Heatran then turned on Marcus along with Bronzong.|
|Bronzong was instrumental in Marcus' plan to destroy Arceus. By hypnotizing Damos, Marcus forced him to betray Arceus and refuse to return the Jewel of Life. However, Bronzong was not acting under its own will, but was being controlled by special armor. Eventually, Damos' special ability to touch the hearts of Pokémon made Bronzong realize what it was doing, and, after the armor was destroyed by Dawn's Piplup's Peck, Bronzong turned on Marcus and helped defend the Trainers that had rescued it.|
