The Deadly Six (六鬼衆,Rokkishū?, lit. "Band of Six Ogres") are antagonists that appear in the Sonic the Hedgehog series. They are a villainous gang of six menacing Zeti. Originally formed several years ago,Dr. Eggman discovered the Deadly Six and tried to harness the power of the group in an attempt to defeat Sonic the Hedgehog and conquer the world. However, due to Sonic's recklessness, the Deadly Six broke free and threaten to destroy the world on their own, forcing Sonic and Eggman to team up to stop them. In the end, the Deadly Six were defeated by Sonic.
According to Takashi Iizuka, the Deadly Six were meant to bring a “sense of danger and humor” to the story of Sonic Lost World. According to another interview with Iizuka at the Summer of Sonic 2013, the Deadly Six are based off of "oni", which is a Japanese demon. The main motif is that the Deadly Six were based off of an "ogre", a mythological creature.
The Deadly Six were formed several years prior by Master Zik. However, it was Zik's student Zavok who would assume leadership over the group, as his demeanor and intelligence made him well-suited for the position.
Sonic Lost World
In the Wii U version and PCversion of Sonic Lost World, the Deadly Six were enslaved by Eggman using a Cacophonic Conch, which Eggman used to cause them pain if they disobey or offend him. Zazz, always eager for a fight, volunteered to fight Sonic first but was defeated twice. Eggman sent Zomom after Sonic next, but Sonic defeated him twice. During a confrontation between the Deadly Six and Eggman, Sonic appeared and recklessly knocked the Cacophonic Conch away. Now free from Eggman's control, the Deadly Six rebelled against him, commanding all of the Badniks they took control of to attack everyone present. Despite this, Sonic, along with Tails, Eggman and his two robot henchmen Orbot and Cubot escaped safely from the danger.
Master Zik was the third to fight Sonic. The Deadly Six then used Eggman's unstable Extractor to absorb the earth's life, growing stronger over time. Zeena fought Sonic fourth. Later on, the Deadly Six decided to capture Sonic and turn him into a robot under their control, but they captured Tails instead. Zor fought Sonic fifth and Zavok fought him last.
After each of the Deadly Six had been defeated twice by Sonic, Zavok proceeded to transform Tails into a robot as an act of revenge. Zazz, Zomom, and Master Zik attacked Sonic and Eggman on Lava Mountain, seemingly killing Eggman, Orbot and Cubot as they fell towards the bottomless pit while Sonic survived. Sonic defeated Zazz, Zomom and Master Zik in Zone 1. Eventually the hedgehog confronted the remaining of the Deadly Six, Zeena, Zor and Zavok and tried to force Sonic to surrender by sending in the roboticized Tails and ordered him to attack Sonic. Tails, however, shot at the Zeti, causing them to flee as Sonic pursued them. One by one Sonic defeated Zeena, Zor, and Zavok.
The fate of the Deadly Six is left unclear, as each of them disappeared after their defeat. However, Eggman vowed to try and control the Deadly Six again.
Other game appearances
In Sonic Dash, Zazz is featured as one of the two bosses fought randomly while in a run. All members of the Deadly Six appeared as cameos in the game's downloadable wallpapers of Sonic Lost World.
The tough and intelligent red leader Zavok! A feisty color to match her feisty personality, Zeena! A fan of the noms, Zomom! Sharp horns and a sharper tongue, Zazz! Braindishing both age and wisdom, Master Zik! And finally, the brooding spy, Zor! Give it up for the Deadly Six!
Zavok, the leader, has a sharp mind and tough fighting skills. Zeena is a cruel siren with a fierce temper. Zomom has a habit of eating everything in sight, and Zazz is crazy about brawling. The elderly Master Zik taught Zavok how to fight, and brooding Zor is the group's spy. Together they are the Zeadly Zix! Sorry, no - the Deadly Six.
In Sonic Runners, during the "Zazz Raid" event, the Deadly Six made their reappearance. This time around, Zazz returned to get his revenge on Sonic by using Power Rings to boost his powers. Each time he confronted Team Sonic however, he was defeated. Between Zazz's battles, the Zeti would go to each of the other Deadly Six for advice on how to beat the heroes, though their advice either did not work or the others would just tease him. However, Zavok told Zazz to keep on fighting, knowing full well that Zazz could not hope to beat Sonic; however, Zazz's constant failures allowed the Zeti to gather the information needed to destroy Sonic one day.
In the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics, the Deadly Six were enslaved by Dr. Eggman with the Cacophonic Conch, but got liberated by Sigma, a villainous robot from an alternate world. The group briefly teamed up with Sigma to aid with his plans, only to betray him when they received power-enhancing armor from him. However, Sigma took control over the Deadly Six using their armor and instated them as his new commanders. They were eventually freed by the Unified Army, and their involvement with Sigma would be erased from history by Xander Payne.
At some point in the not-so-distant future, the Deadly Six would be enslaved by Dr. Eggman once more.
In the Sonic the Hedgehog comic series and its spin-offs published by IDW Publishing, the Deadly Six are a group of villainous Zeti. Their past is virtually identical to their game counterparts', up until after the events of Sonic Forces. During the Metal Virus pandemic, Dr. Starline brought them to the Faceship to control Dr. Eggman's Zombots. Though Starline planned to control them with the power of the Cacophonic Conch, his plan failed and the Deadly Six took over the ship and its Chaos Emeralds. They then split up to conquer various cities around the world and then attack Angel Island, the last safe haven on the planet. Their plans, however, were thwarted by Sonic and his friends. Zavok himself was then sent to Everhold Prison, which he later escaped from following a brief collaboration with Dr. Starline, whom he eventually betrayed.
Similar to other powerful entities, Eggman attempts to control the Deadly Six in order to take over the world, only for them to turn against him. The main difference is that it happens early in the game, rather than towards the end.
Zavok and Zeena are the only Deadly Six members whose names are not mentioned in all the versions of Sonic Lost World.
While the Deadly Six seemingly vanished after their final battles in the Wii U version and PCversion, in the Nintendo 3DSversion they survive and merely fly away like in previous battles.
In the English instruction manual of Team Sonic Racing, Zavok is described as being the "former leader" of the Deadly Six, which suggests that the group disbanded after the events of Sonic Lost World.
↑Sega (23 June 2016). Mario & Sonic at the Rio 2016 Olympic Games. Wii U. Nintendo. Area/Level: Collectibles (Flags). "Zavok is the strongest of the sinister Zeti and the leader of the Deadly Six. As the last disciple of Master Zik, he's a certified force to be reckoned with. Along with his formidable physical prowess, a calm demeanor and penchant for quick-thinking makes his well-suited to leadership. His greatest joy is in improving his skills, which makes the straight-forward competitive nature of the Olympic Games quite appealing."
