Chaos Emerald Championship Ad

An advertisement for the championship.

The Chaos Emerald Championship is an event held at Casino Park during the Shattered World Crisis organized by Breezie the Hedgehog.


After obtaining a Chaos Emerald, Breezie began advertising her tournament, which attracted the attention of Dr. Ivo "Eggman" Robotnik, the Chaotix, and the Knothole Freedom Fighters, who subsequently sent representatives to participate. Both Eggman and Sally Acorn first attempted to buy the Emerald from Breezie; upon failing, the doctor ordered the Hooligans to sabotage the arena defenses in the event that they couldn't win the tournament, and ordered Metal Sonic to travel to the tournament site as well. Sonic the Hedgehog agreed to participate with the stipulation that he only compete during the day, and Espio the Chameleon managed to alter the roster and replace one of the previous participants with Knuckles the Echidna. The first round of the tournament progressed briskly, with Sonic, Amy Rose, and Knuckles defeating their opponents by knock-out while Honey the Cat and Bean the Dynamite won by ring-out. (StH: #267, #268, #269, SU: #66)

The next round of the tournament saw Nack and Bean fight with Nack coming out on top, while Knuckles won a decisive victory over Amy. Another bout took place between Honey and Sonic, with Sonic winning despite Honey's trickery. For some reason, this allowed Sonic to advance to the championship round, while Knuckles was forced to win a match against Nack before progressing to the final stage of the tournament. (StH: #270)

Sonic and Knuckles in Championship

Final Round: Sonic vs. Knuckles

Unfortunately, in the middle of the final round between Sonic and Knuckles, Eggman ordered Nack, Bean, and Bark to disable Casino Park's defenses, leaving Metal Sonic to steal the Emerald from the vault. Metal Sonic evaded attacks from Sonic, Knuckles, Amy, Espio, and Honey, but was intercepted by Tails, who takes the Emerald back. With the defenses reactivated, Eggman ordered Metal Sonic to retreat.

It is unknown whether the tournament was cancelled due to Eggman's interference, or who won if it didn't. However, Team Fighters earned another Emerald, while Breezie claims to have gained massive profits from the world watching the heroes save the day.



The tournament bouts took place in virtual arenas that recreated locations from around Sonic's World. A competitor could be eliminated by one of two ways-being knocked out by their opponent or being jettisoned from the ring by some fashion or other. (StH: #269)

Background Information

  • The Championship appears to be based on the plot of Sonic the Fighters, but involving only one Chaos Emerald as opposed to all of them.
  • Curiously, the tournament does not appear to have followed a typical bracket style of competition, as Knuckles participated in three fights to reach the championship match while Sonic only fought two.
