The Mysterious Life Form, Chaos is the 28th episode in the first season of Sonic X. In the English dub, it is known as A Chaotic Day. This episode is the second part of the series' adaptation of Sonic Adventure.


Sonic, Knuckles, Chris, Chuck and Big are discussing the Chaos creature at Chuck's house. Knuckles reveals that the Chaos creature appeared on Angel Island and shattered the Master Emerald. Big reveals what happened when he and Froggy found the Chaos Emerald. They also reminisce over their battle with the creature in Station Square. Sonic then visits Tails in his lab, where he reveals that he is using the Green Chaos Emerald to power the X-Tornado. They decide to use the emerald to find the other emeralds before Eggman.

Meanwhile, at a casino (based on Casinopolis from SA1) which has been damaged, Knuckles arrives, and with the help of the police, finds some shards of the Master Emerald. When he touches the shards, he experiences a vision of an ancient tribe of echidnas arguing over using the Chaos Emeralds to attack another tribe, whilst a female echidna (Tikal) argues against it. Knuckles wonders what he just saw.

Sonic and Tails use the Chaos Emerald in the X-Tornado to locate the Blue Chaos Emerald, which is buried. Sonic uses his Spin Dash to retrieve the emerald, and they are both celebrating when they are attacked by Eggman. Tails is stunned by Eggman, who steals both the Chaos Emeralds and feeds them to Chaos, who turns into Chaos 4. Sonic battles Chaos on some lillypads and defeats him, but Eggman simply rescues Chaos and retreats to the Egg Carrier flying overhead.

The Egg Carrier flies to Station Square with Tails in pursuit with the X-Tornado. Tails attacks, but suffers heavy damage whilst barely scratching the Egg Carrier. Meanwhile, on the ground, Amy sees the Egg Carrier fly overhead, when a small bird with a jewel tied around it's neck lands next to her. She decides to take the bird with her and call it Lily.

Tails, Sonic and Chuck discuss the events in Station Square. Chuck reveals the X-Tornado suffered heavy damage, whilst Tails laments letting Eggman get away. Amy is out shopping with Cream and Lily and discusses finding Lily's home and family. Suddenly, they are attacked by one of Eggman's robots, who grabs Amy and Lily. Sonic arrives and tries to stop the robot, but fails as it flies off with Amy and Lily.
