Zakira

Zakira Fua is an evil duelist and the main antagonist of both Shori and Shobu, and is also the one controlling Yumama (his younger sister) from the start of the series. In the Versus Revolution, he reappears in Katta Kirifuda's time, who is Shori's son and Shobu's younger brother, through Basara Akagiyama and the card he uses in the past.

He is the leader of the Fua Duelists. He is marked as (Z) and ranked as 1st in the organisation.

History
He was known as "No. 1" when he was young. In his 14th birthday, he challenged the Fua Duelist's leader at that time, "Zeus" in a duel. He used Necrodragon Guljeneraid and Supernova Apollonus Dragerion to defeat Zeus and became the cult leader known as "Z".

He later entered university alongside Ash, Oasis and their friends. On his graduation day, his professor asked a question which was known as "The greatest Mathematics mystery". Zakira answered the question correctly and was invited to duel against the professor.

While the professor's Discard tactics and Vacuum Crawler lock proved to be a challenge for him, Zakira used a reanimate strategy using Romanov the 1st, Lord of the Demonic Eye and Beginning Romanov, Lord of the Demonic Eye and won the duel. Since then, he decided to destroy all duelists.

He cannot be physically damaged outside of a duel and also knows special abilities such as curses and psychokinesis.

Anime
His first appearance was in Volume 14 of the Series 1 of the manga.

He then later appears in the Duel Masters Charge, Duel Masters Cross and Duel Masters Cross Shock seasons of the anime.

Duel Masters Charge
His goal is to obtain the "Duel Master's Proof" and use it for his evil means. He has multiple agents working under him, and operates from a large castle. His agents are ranked in terms of increasing power in alphabetical order from A to Z (Z being himself).

Duel Masters Versus Revolution
The area where Duel Masters Land was located is where Zakira had destroyed most of the duelists during Shobu's time. The card he uses was kept in an ancient seal in the deep underground of the park, in which only the President of the park and Duemouse were able to access. Despite being sealed for years after Zakira's demise and Shobu's disappearance, the dark spirit was able to reach Basara, prompting him to break the seal and obtain the card. After a chain of events which almost lead to his assumed demise and Shobu's 'death', Zakira was actually alive and remains in one of the destroyed bases in the frigid lands of Antarctica. Basara was guided by the light from Forbidden, which lead him to his location. Zakira had awaited his arrival and dueled him in order to test his worth of having Forbidden. As the whole area was converted to an actual duel field, the duelists takes physical damage if a shield is broken. During the match, Zakira viewed Basara's Invasion cards and speed based deck as interesting. Even though Basara managed to summon Forbidden, Zakira destroyed the creature with All Delete. Seeing that Basara's hate and thirst of revenge allows him to use the card, he let Basara have the unsealed version of the said creature before giving him a warning and fading away.

Duel Masters: Fighting Edge
After the revolution, the more powerful members of the cult started to appear. He treats Shobu's resistance as a joke and his cult members attempts to capture the Duel Masters from all around the world.

In the second world tournament he calls all of his Fua Duelists and attempts to collapse the tournament. However, White resisted and the plan failed. Hakuoh then is defeated by Yesman and his defeat is even shown to the public. He then challenges Shobu and used Heavy Death Metal and Zero Phoenix, Phoenix of Darkness to have Shobu close to losing only to be defeated by him.

Duel Masters: Star Cross
A mission was started in Antarctica along with all of his cult members but was betrayed by Xanadu who is an impostor as the original Xanadu was revealed to have been killed. Nearly all the cult members were dead aside of a few but the few were attacked by Xanadu's cloning ability. He himself dueled Xanadu and defeated it. However, before it dies Xanadu unleashes a destruction ray and Ash blocks the attack with Zakira and Ash receiving massive damage. By this point, all Fua Duelists except for Ash and himself had died.

Zakira's mind was disrupted by Xanadu but he managed to continue his plans. He broke free of the mind disruption and choose to duel Adam. Feeling that he and the cult's freedom has been deprived, he decides to defeat Adam and liberate the cult.

However, he dueled against Adam with Mad Rock Chester deck and had no way to win against the original gods and Rumble Lecter, Terror Awakened. He lost and was killed along with Ash.

Zakira seemingly died after this duel against Adam and was not seen again.

He then became invincible and cannot be destroyed by Bolmeteus Steel Dragon's flames and sworn for revenge against the universe, grew wings and flew in the vastness of space.
