Mask of Dark Earth
The Mask of Dark Earth, as it appears during Sly 3: Honor Among Thieves
Until the recent events of Rumble Down Under, it was protected by the Guru. The mask was originally hidden in an underground cave in the Australian Outback, but was reawakened when a team of opal-seeking miners and their equipment dug into its "prison".
Sly 3: Honor Among Thieves
The mask moves on its own accord, floating in mid air and possessing people to do its bidding. While under its control, the wearer becomes a constantly enraged giant. A particularly poignant example of this occurred when Carmelita Fox, pursuing the Cooper Gang to Australia, was possessed by the Mask and subsequently freed of its control by the selfsame gang. But unlike the mask's other victims (the miners), when it possessed Carmelita, Bentley tried to use his sleep darts to knock her out so they could take the mask off of her and hopefully destroy it. Unfortunately, it had the opposite effect. The chemicals in Bentley's sleep darts reacted to the mask and made her even bigger, growing to the height of 100 ft. The Mask of Dark Earth was destroyed at the end of the Cooper Gang's operation "Moon Crash", when Sly climbed up to her face to remove the mask, which returned Carmelita to normal. Carmelita's backup forces eliminated the evil artifact, but it killed the backup forces when it exploded.
The Mask of the Dark Earth is capable of possessing people's minds and making them much stronger, aggressive and larger than usual.
- The Mask of the Dark Earth is the only Sly Cooper villain that is not an animal.
- Likewise, the Mask of Dark Earth is the only Sly Cooper villain that is actually an inanimate object. Though technically it is not inanimate, because it houses a spirit, can think, move and interact.
