Personality[]
Meison is a highly intelligent, calculating, recourceful power-hungry mechahuman, who will not stop at nothing to destroy the Biomen and subjugate and conquer the Earth for his master Doctor Man.
He is also highly calculating, scheming and clever, and is capable of creating a cunning schemes and plans for achieving his goal. Meison's personality changes during the series. For the most of the series, Meison was highly selfish, arrogant, destructive, warmongering and self-confident, yet he was still loyal to his master Doctor Man, believing that Doctor Man was a true mecha human, who gathered such a powerful army under his command and was the only one who could control such a powerful empire.
Meison admired and respected his master and wanted to impress Doctor Man the best he could by enforcing his orders and fullfilling his dream of the world domination. Meison also had a big rivalry with his fellow Gear generals, with them being frequently envious of him being praised and congratulated by Doctor Man for his successes in the plans of the Neo Empire. However, everything changed half way towards the series, when Meison discovered that his master wasn't the true mecha human, but actually the mechanically modified human. Meison realized that Doctor Man's true identity as the father of the Shuichi.
From that time, Meison decided to no longer serve Doctor Man and overthrow him, believing that only mechahumans deserve to rule the Neo Empire and not a human. He eventually betrayed and decided to kill his former master and take the Neo Empire for himself, even going so far, trying to convince the other generals of the Gear to help him overthrow Man.
At first his efforts were successful as he successfully convinced the other Gear subordinates to betray Doctor Man and overthrow him, but eventually it was their fatal mistake, as Man discovered their betrayal and reprogrammed them into the mindless mecha humans, completely loyal to him. Meison became more ruthless, violent and determined to destroy the Biomen, no longer possessing the free will and mindlessly following Doctor Man's commands.
