Dark Guardian (ダークガーディアン Dāku Gādian?) is a boss that appears in Sonic Unleashed. It is one of Dark Gaia's Minions. Following the dispersion of Dark Gaia's essence across the planet, its evil influence came into contact with the large amount of moon energies found inside Shamar's Gaia Temple and twisted it to form Dark Guardian.


Dark Guardian looks very much like a heavily armored Deep Nightmare. While not nearly as conspicuous as the Deep Nightmare, Dark Guardian mostly resembles a humanoid lizard, but unlike the Deep Nightmare, he has thin arms with four-fingered hands, no spikes on his back and a straight tail. He possesses a horn similar to the Deep Nightmare, but it is turned over the right side of his face, which is highly detailed with pointed purple and white streaks. He also has small white eyes and long green hair.

Unlike most of Dark Gaia's other minions, Dark Guardian wears non-organic body armor. He has gauntlets on his hands, upper arms, feet and lower legs, with a golden ring around his right wrist. He also carries a large warhammer with a round end that is occasionally surrounded in purple electricity.

The size of Dark Guardian differs between the versions of Sonic Unleashed; in the Xbox 360/PlayStation 3 version, Dark Guardian is about as tall as Sonic the Werehog, while in the Wii/PlayStation 2 version he is almost as tall as a Titan.

Powers and abilities

Dark Guardian has abilities similar to that of the Nightmares, except his are more powerful. He can both stretch and enlarge his right hand over long distances, and strike with such force that it can leave Sonic the Werehog dazed and immobilized for a short while. He also possesses a Nightmare's defensive maneuvers, which involve jumping back to avoid attacks and guarding against assaults with his arms.

Dark Guardian is incredibly fast, capable at moving at such high speeds that he is almost invisible to the naked eye. He is also capable of energy projection, allowing him to launch powerful purple energy balls. In the Wii/PlayStation 2 version, he is also capable of teleportation.

Dark Guardian's power stems from lunar power (the energies from the moon) which it draws from the Moon Altar. This allows Dark Guardian to summon orbs of energy to give him a power boost, or even heal himself from any damage he might have received. In the Xbox 360/PlayStation 3 version, this ability makes Dark Guardian nearly invincible. However, the Moon Altar is also Dark Guardian's greatest weakness, as destroying the altar will cut off Dark Guardian from his power supply, leaving him weak and unable to heal himself.


Besides physical capabilities, Dark Guardian wields a hammer imbued with the power of thunder. With it, he call forth lightning bolts to strike Sonic from above, unleash a vortex of lightning, or simply smash Sonic with it while charged with electricity.


Wii/PlayStation 2

Dark Guardian is the third nighttime boss in Sonic Unleashed, and the game's overall fifth boss. It is fought with Sonic the Werehog, but can first be fought after unlocking its Boss Stage in Shamar's Gaia Gate, which can be done after completing Arid Sands Night Act IV: Altar of Oblivion. The boss battle takes place in a closed arena.

Boss guide

The strategy to defeat this boss is just to brawl with the Dark Guardian. This battle is like fighting a regular mini-boss (such as a Titan) but tougher considering that the player is unable to use Unleashed Mode. He can extend his arm to punch Sonic. When the player brawls out at him, he will swing his hammer all around causing Sonic to be stunned. Dark Guardian can also do quick steps to step away fast. After a while, he will teleport to the other end of the arena and slam his hammer down, causing lightning to strike various parts of the field, replenishing his Vitality Gauge. If the player dashes over to attack, he will take more damage than he normally would.

If he swings his hammer around and knocks Sonic back, this will trigger a quick-time event where Dark Guardian will rush at to attack Sonic, If the player clears the Real-Time Interaction, they will block him and punch him causing a little bit of damage to him. If the player fails, Dark Guardian will hit Sonic into the air. Though, if the player presses the right button, Sonic will dodge the hammer attack and kick Dark Guardian on the back of his neck. If they fail, the hammer will slam down on Sonic. When the player hits the ground, Dark Guardian will charge a blast that packs quite a bit of damage. If the player does the timing right, they will be able to dodge it. If they fail, the player should take massive damage. There is not anymore after that via such simplicity, and with luck, it is possible to beat him before he begins to teleport if one is fast and careful enough.

The time needed to "S" Rank is 5:00. Failure to make that time will yield a "C" Rank. Therefore, no Sun Medal will be awarded.

Xbox 360/PlayStation 3

Dark Guardian is the third nighttime boss in Sonic Unleashed, and the game's overall sixth boss. It is fought with Sonic the Werehog, but can first be fought after unlocking its Boss Gate in Shamar's Entrance Stage, which can be done by completing the nighttime version of Arid Sands Act 1. The boss battle takes place in a closed arena with several fences forming a labyrinth.

Boss guide

The strategy of this boss is to destroy the moon altar by pushing boxes with white cubes to the altar, which causes them to act akin to a lightning-rod of sorts to damage the moon altar bit by bit per each box pushed over. The arena is between the Sun and Moon altars and the player must use them to their advantage. Hit Dark Guardian a couple of times to stun him, and then push the boxes over to the Moon Altar to destroy it, which in turn causes damage to the Dark Guardian.[1] Each time the player knocks out the Dark Guardian, he will keep coming back (via the altar sending an energy orb-surge to the boss, reviving him from his unconscious state and healing his HP to a certain threshold).[2] Thus, the moon altar must be damaged in order to bypass the said threshold with un-heal-able damage to his HP.

There are several obstacles preventing the player from combating Dark Guardian: spiked fences randomly pop up and down, blocking Sonic's path, and Nightmares (and their deep variants) will spawn and try to hit Sonic or push the crates the other way. Also, Dark Guardian will try to hit Sonic or summon lightning (which is why it is recommended to take him out first so he cannot interfere with the player). If a part of the altar is destroyed and he is still conscious, a quick-time event will occur. Dark Guardian will rush at Sonic and try to punch him. The player will be prompted to press a button to block the attack and knock him over. Fail to do this and the Dark Guardian will knock Sonic into the air, where the player are prompted to press another button to avoid his hammer attack. If the Guardian hits Sonic, he will knock him to the ground and charge a blast at him. The player are then prompted to press another button to dodge, or Sonic will take massive damage. All the player needs to get three boxes to the altar. If Dark Guardian is still alive after that, go up to him and use all the power Sonic has and beat him to the ground.
