Dweller-in-Darkness

Just before the crystal shattered, however, the Phoenix Force telepathically reached out to the minds of all life and united them in peace, foiling the Dweller's scheme.

[2] In this new universe, when he first came to Earth, the Dweller-in-Darkness fed upon the fears created by the war between the humans of Atlantis and the Deviants of Lemuria.

When Atlantis sank, the Dweller absorbed the fear of the inhabitants and used it to create D'Spayre and ordered him to kill Zhered-Na in revenge.

These humans would then kill themselves but turn into Shade Thralls, powerful creatures who served the Dweller, but were vulnerable to light.

The Dweller witnessed the destruction of his Shade Thralls by Strange and Clea and determined that they were the largest threat to him on Earth.

Most of the Fear Lords agreed, but the Straw Man, who was benevolent to humanity, disagreed with their plan and warned Strange.

[volume & issue needed] Hawkeye and Black Widow became involved in a mission against some of the servants of the Dweller-in-Darkness on behalf of the Secret Avengers.

He also has other undefined mystical powers: he can create independent creatures out of fear like D'spayre and he can turn humans who die under his influence into Shade Thralls, beings made of shadow with superhuman strength.

The Dweller is immortal, does not age, and even the sorceress Zhered-Na, assisted by powerful beings like Agamotto and Valka, could only banish him, not destroy him.

The Dweller's head is attached to a robotic body, which possesses superhuman strength, but it can detach and move with the tentacles near its mouth in case of emergency.

During the Secret Wars storyline in the Battleworld domain of 2099, Martin Hargood (the 2099 version of Baron Mordo) used Alchemax's virtual unreality laboratory to summon the Dweller-in-Darkness.
