Haman Karn is a character from Mobile Suit Zeta Gundam & Mobile Suit Gundam ZZ and is the one of the main antagonists of Knights of the Multiverse Season 2. She is the leader of Axis Zeon, and formed an alliance with the Romefeller Foundation and OZ to try and bring order to the Multiverse.
On the outside, Haman comes off as a cool, collected, and hardened leader, who's often very charismatic and seems to care for the well being of her soldiers, even teaching the principles of war to some. However, all this is a ruse to cover up her true self; Haman's real character is one that desires power, not caring who she has to use or discard to get it. She is very skilled at manipulating others, playing on their fear and ambitions to use them as she sees fit. Kamille, upon first meeting her, commented that he felt a dark, malevolent aura around her, thus reflecting the depth of her dark personality, possibly even implying she is truly evil, to the point where, when they first met during the Gryps War, he called her nothing more than a warmonger. While she believes in reforming the Earth for the better, she has no tolerance for Earthnoids, viewing them as corrupt, greedy individuals whose "souls are weighed down by gravity," and as such must be rid of, if Earth is to be saved under the aristocratic rule of spacenoids, with her herself as empress.
It is important to note, though, that Haman wasn't always like this. When she was younger, Haman had a sweet disposition as a young teenager, growing up in Axis after the One Year War and having never seen the Earth, and had to endure a hard life growing up as Axis was not well suited to support life, and it was not any better with the looming threat of the Federation possibly attacking them. She was also a romantic of sorts, as she became romantically involved with Zeon's own Red Comet, Char Aznable. Though as Haman had to train to be a soldier and possibly felt obligated to protect the people on Axis, viewing their treatment by the Federation as unjust. Thus Haman's personality in the anime is a result of her troubled upbringing, never having had the chance to be a child and enjoy life, she became dark, cold, and isolated from the rest of the world, which she states is what made her stronger and is her core strength.
