The Snowy Kingdom and the Tiger (Sonic Adventure 3: GX)

This page contains the story of Knuckles the Echidna in full detail, in the game Sonic Adventure 3: GX. Secondary characters in Knuckles' story involve Julie-Su and Big the Cat, who have their own gameplay style and levels.

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.

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.

Mission 1: Defeat 25 enemies (Knuckles)

(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 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.

Boss 1: Fang the Sniper (Knuckles)

Fang manages to robb the treasure and flees to the city. Knuckles and Julie-Su chase after him.

Stage 5: Mega Central (Knuckles, Julie-Su)

After they confront Fang, Dr. Eggman's fleet appears in the sky and Fang escapes with it, leaving behind a group of Dark Legionaires. Knuckles now understands that something doesn't seem quite right, as the Dark Legionaires are working for Eggman.

Mission 2: Defeat 30 enemies (Knuckles, JulieSu)

<p style="text-align: center;">(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 still wants to go after the Egg Carrier, but Julie-Su advises him that they go find the other treasures first and deal with this afterwards. Knuckles agrees and they head to where the compass shows: the sea.
