Zack

Zack (ザック, Zakku) is a DJ from the Dead or Alive series, who first appeared in the original Dead or Alive. A self-taught Muay Thai boxer, Zack only enters the Dead or Alive Tournaments for money and fame.

While achieving a place in the top three in the previous three tournaments, either due to other contestants withdrawing or through his own efforts, Zack is the "winner" of the fourth tournament, as Helena Douglas gave up her title of winner to him.

He plays a huge role in the Dead or Alive Xtreme spin-off series, as he is the owner and creator of Zack Island, where the games take place.

The First Tournament
After hearing about the Dead or Alive tournament, Zack enters to increase his popularity and make a name for himself. He apparently succeeds in that endeavor, to an extent. He also earns a high enough ranking in the tournament to gain a prize of significant monetary value.

The Second Tournament
Zack entered the next tournament to please his fans and gain more money. Through the rounds, he had to face Tina Armstrong, who he took a fancy to, and tried to ask her out. Tina wasn't impressed and refused his advences, giving him a mirror and told him to "use it", hinting that she didn't like his appearance. Taking slight offence, the two fight it out.

As Zack went through the rounds, he meets Tina's father, Bass, who, being a protective parent, became enraged when he learned Zack liked Tina. He also meets Leon, who seems to know him, but Zack claims that he doesn't know the man at all (and pulls the same mirror insult on Leon that Tina did.) After the tournament, Zack once again succeeded in this task and returned to his life of leisure.

The Third Tournament
After exhausting all his financial reserves, Zack entered the third tournament to earn more money so that he can enjoy a vacation. During the tournament, he has to fight Gen Fu, who wants the prize money to pay off his granddaughter's hospital fees. Althought Zack tries to tell him that if Gen Fu let him get the prize money, he could double it through gambling in a day, Gen Fu doesn't believe he can, and the two fight. He also fights Bass once more, and both fight over the who is going to win the prize money.

In the end, Ayane actually came first, but due to her departure after the tournament, Zack claimed the title by default, and got the prize money. With the winnings, Zack went to Las Vegas, and not only did he meet his future girlfriend and partner, Niki, but they also won a fortune from the Roulette tables together.

The Fourth Tournament
Despite public expectation, Zack went right on to his next conquest by attempting to climb the DOATEC Tritower during the fourth Dead or Alive Tournament. Despite nearly making it to the top, Zack was blown off the side of the building during the initial destructive explosions that were the result of the Mugen Tenshin Ninja Clan’s attack on the corporation. After watching the explosion in shock and disbelief, he turns around to find Bayman who immediately confronts Zack. Still in shock, he fights Bayman.

When Helena activated the building’s self-destruct and attempted suicide by staying inside the building, Zack was the only fighter able to get to her. Having his extraction pilot fly through the blazing tritowers, he pull her from the roof she was standing on seconds before the building’s detonation. Because of this, Helena gave her first place title to him.

Afterwards, Zack and Niki are reacquainted and go on an expedition to Egypt where they discover and explore a crypt, finding a large fortune, fighting off and fleeing an army of undead skeletons in the process.

Appearance
Also see: Zack's Outfit Catalogues Zack is a young African-American man who likes likes keep up on his appearance. As he keeps changing the style of his hair and dyes it constantly, his real hair color is unknown. His eye colour is also unknown, as he chooses to wear dark sunglasses and goggles with colored lences that hide his eyes.

Often seen wearing bright, colorful, and sometimes absolutely bizarre costumes in the tournaments, Zack has one of the most flamboyant appearence in the series, as well as being the only character that goes through the largest change of appearence every game, since he changes his hair so much.

One of his recurring costumes, and possibly his most iconic outfit, is a tight full-body "alien suit". Made from silver, reflective material, the suit comes with boots and gloves with neon green trim, a blue screen on his chest, as well as a hood with red goggles. The hood gives Zack "pointed ear", and a flowing antenna on his forehead, which can glow purple when he taunts other fighters.

Personality
Zack is perpetually happy, flamboyant and a natural showman who lives to entertain and tries to never disappoint his fans. He is constantly smiling and bares a positive light about himself, simply shrugging off any setbacks and insults that may come his way. Wherever he goes, Zack often makes commotion and creates scenes. With his cheerful ways and sometimes weird behaviour, Zack is often a source of comic relief in the series.

When fighting, he likes flashy, showy moves, and keeps up a constant patter of talk and laughter. His ego has led him to create autographs and statues in his image, even naming an entire island after himself. Zack is also money-hungry and enjoys making money; he enters the tournaments solely to win prize money to fund his luxurious lifetime, and he is a master at the casino table.

Etymology
The English name Zack is a short form of Zachary, a form of Zacharias, which in turn is a Greek form of Zechariah. The name Zechariah is from the Hebrew name זְכַרְיָה (Zekharyah) which means "Yahweh (God) remembers".

Tina Armstrong
Since Dead or Alive 2, Zack had an attraction to Tina Armstrong but failed many times to make Tina fall in love with him, mostly due to his loud, strange appearance, which Tina did not like the look of at all. After falling for Niki, Zack stopped chasing after Tina. The two fighters remain friends, but Zack is still often teased by Tina; if the two of them win a tag-team fight, Tina would high-five Zack, but as he does it back, she would jump to the side and let him fall onto the ground.

Niki
After meeting in Vegas in Dead or Alive 3, Zack fell in love with Niki and the two started dating. The two did break up after Zack Island’s initial destruction but reunited again during Dead or Alive 4 and the pair remained together during the resurrection of Zack Island and the island’s second destruction. Zack refers to Niki as his lucky charm and even named a beach on his island after her. The two of them share the same greed for money and luxury.

Bass Armstrong
Zack and Bass have formed a kind of rivalry since Zack’s "courtship" of Tina; Bass is highly protective of his daughter and saw Zack as a threat, although Tina was obviously not intrested in Zack. After Zack stopped crushing on Tina, it's unknown how the men's relationship has turned, but this rivalry has led to Zack naming a small headland of beach after Bass as a private joke.

Helena Douglas
Zack saved Helena from her attempted self-sacrifice during the destruction of the DOATEC Tritower. Since then the pair seem to have become business partners, with Helena visiting New Zack Island in order to discuss the possible resurrection of DOATEC.

Leon
In Dead or Alive 2, Leon claims that he and Zack had met before, although Zack says that he has never met him before. It is unknown if the men ever did meet before and Zack just forgot, if Zack is just denying it or if Leon confused Zack for someone else. In Dimensions, they have custom entrances and winning animations when put fighting together in a tag team match.
