Knuckles' Story
It has been some time since Immarius and the Gravitus attacked the Angel Island and destroyed most of its Ancient Cities. Teotihuacan has now been abandoned and its inhabitants have created colonies on the surface of the island and are now living peacefully.
Knuckles is seen gliding over the Angel Island. We hear from his thoughts that he has signed a peace treaty with the

Dingoes and is now heading back to the village to meet up with his father Locke. However, as soon as Knuckles arrives, he encounters most of the village burned rampaged and the villagers gone. Knuckes wanders around the place until he encounters his father, Locke, lying down to the ground. Knuckles rushes to his father. Locke tells Knuckles that he must do whatever it takes to protect the Angel Island and gives him a key from his pocket. Locke tells him that to use the key whenever he is ready and how much he loves him. Locke then dies. A saddened Knuckles moans for his father's death and burries him. After some sobbing, Knuckles gathers his thoughts on who murdered his father and what has happened to his village. Knuckles takes out the key Locke gave him and looks at it. He decides to go to the Oracle to gather some information about the key.
Adventure Field: Angel Island
(You will have to talk to the townspeople first. You will encounter some frightened Echidna villagers who will give some information about what has happened and where the Oracle is. They will tell you to go to the Tropical Sanctuary).
Stage 1: Tropical Sanctuary (Knuckles)
At the Oracle, Knuckles asks what this key is exactly. The Oracle responds to Knuckles that mankind is in terrible danger and that Knuckles must protect the Angel Island from a new threat. Knuckles was given this key in order to unlock a secret in Teotihuacan, which can be unlocked only by the wielder of this key. The Oracle also informs Knuckles that a Dark Legion has appeared, which is not from this world and that Knuckles must gather allies to fight them back. Knuckles departs from the Oracle and decides to head to Teotihuacan to find and unlocok this secret with his key.
Adventure Field: Angel Island
Stage 2: Lost World (Knuckles)
Knuckles arrives at the ruins of Teotihuacan and explores the site. After a short time, Knuckles encounters a gate. After opening it, he ends up in a chamber. The chamber is small and nearly emtpy. Knuckles searches the walls and encounters a hole. He uses his father's key once more and opens a small door which contains a papyrus inside. The papyrus is written by Locke, Knuckle's father, for him and contains a note. It starts off by saying: " Knuckles, my son, by the time you will be reading this, I (Locke) and the entire Brotherhood of Guardians will have died". And it continues that by the time he reads this, grave danger will pledge the island. For this, Locke has been hidding all this time a powerful weapon called the Enerjak suit so that it would not be falled into the wrong hands. However, now that there has been a new threat, Knuckles must go and find it and utilize it to defeat those who want to destroy the world. To find this suit, Knuckles must find and gather all of the scattered items of the past guardians of the Master Emerald, the Sacred Treasures of the Brotherhood of Guardians for when all together, they reveal the suit's location. The letter ends with the phrase "I have faith in you, your father, Locke".
Knuckles takes the papyrus and the key with him and leaves the chamber. Just outside the ruins, Knuckles is unexpectedly ambushed by a group of black hooded figures, the Dark Legionaires.

(Here, you control Knuckles and your mission is to defeat 25 Dark Legionares. You fight them in a location just outside the Lost World).
Knuckles and Julie-Su's first interaction
Knuckles manages to defeat most of the Dark Legionares. Some of them manage to escape. Knuckles catches a Dark Legionaire and is about to harm him, until the mask falls of, revealing to be a female echidna. Knuckles gets embarassed and apologizes for his actions. He asks her what she's after and what her name is. She says her name is Julie-Su and walks away. Knuckles goes after her and asks her questions such as where she comes from and what is she doing here. Julie-Su says that she is after some ancient items and therefore, she beat up a Dark Legionaire and disguised herself as one so that she went undercover and unnoticed by the Dark Legion. Knuckles tells her that he is looking for the same thing and suggests they co-operate, but Julie-Su rejects it as she prefers to work alone. After many negotiations, Julie-Su decides to work with Knuckles to find these ancient items. Julie-Su suggests to the city, but Knuckles suggests they head to the Master Emerald, to see if he can get some answers from there.
Adventure Field: Angel Island
At the altar, Knuckles touches the Master Emerald with his two palms and closes his eyes. Knuckles sees a vision signaling that he must start off from the city. Something significant is going to happen there soon. Knuckles shares his vision with Julie-Su and head to Central City.
Adventure Field: Central City
It is now night time. Knuckles and Julie-Su arrive at downtown Central City. Just as the vision had predicted, the city is attacked by Dr. Eggman's armada of airships.
Stage 3: City Siege (Knuckles, Julie-Su)
By the time Knuckles and Julie-Su arrive at the site of the incident, Eggman's fleet and the citizens have all left. With this opportunity, they sneak in the museum, after being informed of what Eggman's intentions were. After looking at the artifacts, they stumble upon one that catches their sight. An ancient compass with the symbol of Knuckles' tribe carved on it. Knuckles takes it and realizes that it belongs to one of his ancestors, Thunderhawk. The scene ends at that point, where Julie-Su and Knuckles are looking at the compass.
A cutscene follows. We are introduced to Dr. Finitevus in his laboratory (location unknown), where he is

examining test subjects, namely Echidnas (which he captured after invading the island). As he is working, we see Dimitri floating by him. Finitevus explains to him that he is examining the Echidnas to discover their bloodline and how they are affected to Chaos energy. After a talk, Dimitri informs Finitevus not to forget what their true intentions are. Finitevus reminds him that they teamed up in the first place to acquire the Enerjak suit and grant Dimitri immortality, since he is slowly losing his life. The camera zooms at one of Finitevus' victims, who is Dimitri's own son The cutscene then ends.
The story switches back to Knuckles and Julie-Su, who are walking in the streets of the city. With the ancient compass and the second Ancient Treasure of the Brotherhood in their posession, Knuckles and Julie-Su head to where the magic compass points to find the missing treasures. First, the compass's needle points at north, where the mountains of Blue Ridge Zone are located. They head towards the mountains.
Stage 4: Rail Mountain (Knuckles, Julie-Su)
After climbing on the mountains, Knuckles and Julie-Su find what they were searching for, Edmund's Shovel Claws. However, they are soon confronted by number 1 bounty hunter Fang the Sniper, who, believing it is one of the Samarkanda artifacts, tries to steal it.

(Here, you will have to defeat 30 enemies. 15 of them with Knuckles and 15 with Julie-Su).
Knuckles and Julie-Su defeat the Dark Legionaires but they are too late to chase after the Egg Carrier.

Knuckles agrees and they head to where the compass shows: the sea.
Adventure Field: Central City
Stage 6 (a): Blue Bay (Knuckles, Julie-Su)
At the beach, the compass leads them to the bay where they find Big the Cat, who is seen fishing along with Froggy carelessly. Knuckles and Julie-Su approach Big and ask him if he's seen any Sacred Treasure. Big tells them that there is something he is trying to catch under the sea that looks like a Sacred Treasure. After some struggle, Big fishes for the Sacred Treasure, Steppenwolf's Hammer Gloves. Big gives them to Knuckles and they thank him. Big tells them that he has seen some very similar items in his village and offers to take them there for hospitality.

Stage 7: Olive Retreat (Knuckles, Big)
The story is interrupted by a cutscene. We see Dr. Finitevus and Dimitri, in his headquarters, watching Knuckles, Big and Julie-Su through a portal. A Dark Legionaire reports and Finitevus says that there are some minor problems in his plans, as Knuckles and his team are thwarting his plans in getting the Sacret Treasures for himself. He orders the Dark Legion to capture them and bring them here.
Meanwhile, (now night time) Knuckles, Julie-Su and Big arrive at the Mysterious Cat Country, Big's village. They meet up with the country's chief Lupe, who welcomes them. She tells Knuckles that she had been awaiting for him in order to give him one of the Sacred Treasures of the Brotherhood that was given to her in order to hide it and hand it over to Knuckles when time was right. Lupe gives them Floren-Ca's Twin Daggers. Knuckles thanks them and forms an alliance with the Mysterious Cat Country. They go out to gather and celebrate Knuckle's coming. But to their dismay, the Mysterious Cat Country is attacked by an army of Dark Legionaires, who seize the villagers and burn down the entire village. Knuckles tries to fight them off, but is somehow struck in the head and loses his conscious. The cutscene ends there.
Knuckles wakes up chained on a wall by the arms, in what seems to be a castle. As he yells for help, a mysterious cyborg appears and threatens Knuckles. His name is Xenin. Knuckles asks him where he is and what he is doing here. Xenin tells him that he is in Dr. Finitevus' headquarters and soon, he (Knuckles) will become part of the Dark Legion himself.
Meanwhile, Julie-Su wakes up in a now devestated village. She searches for any survivors.

Shade tells Knuckles that Finitevus invaded the Angel Island with his Dark Legionaires and wiped out most of its population, some imprisoning them here. Knuckles tells Julie-Su, Big and Charmy to follow Omni-Viewer to safety, whereas Knuckles, Shade, Espio and Vector find another route to the exit so they don't get caught.
Adventure Field: Angel Island
(The Adventure Field takes place only inside Finitevus' base).
Knuckles, Shade, Espio and Vector enter a hidden room in attempt to hide from soldiers in the hallway. The room seems to be different from other rooms in the base. They examine it. Knuckles looks around and finds some documents scattered around the desk. He looks at them carefully. They are about the Knuckles' Tribe and about the Brotherhood of Guardians. Knuckles looks at a paper with various images of Echidna Guardians whose heads have been marked with a red X. Below it says ELIMINATED. Knuckles becomes anxious and reads them faster. He recognizes some figures in the pictures. He nearly sheds a tear when he recognizes his father, who has also been marked with an X. He now realizes that they are below Haven, the Brotherhood's old hideout, which has been found by Finitevus. He takes as many documents as possible with him and orders the team to leave this place. Before he leaves the room, he encounters a flute on top of the desk. He takes it with him and leaves.
