Long ago, the wizard King Olnar sat on the throne of the
Dark Dimension. He is visited by
Umar and
Dormammu, siblings of a race of magical energy beings called the Faltine. Olnar merges the Mindless Ones' home dimension with the Dark Dimension. They rampage throughout the lands, killing many, including Olnar, and almost killing Umar and Dormammu. The siblings create a barrier to keep them contained. The Mindless Ones are most often seen in the employ of Dormammu, who develops a limited ability to control their actions. They have also been utilized by others such as
Doctor Doom,
Doctor Midas (in
Marvel Boy) and a fellow Faltine named Rorkannu (in
Nextwave: Agents of H.A.T.E.). Doctor Doom uses them after gaining high levels of magical power via a deal with demonic entities. The Mindless Ones are utilized to beat on
Ben Grimm, a member of the
Fantastic Four, in a test of his durability. When
Spider-Man is banished to the Dark Dimension by a brainwashed
Portal, he is attacked by a group of Mindless Ones. To rescue him,
Darkhawk and
Sleepwalker battle
Toad's
Brotherhood of Mutants and break
Sauron's control over Portal so they could retrieve Spider-Man. A gang of Mindless Ones follow Spider-Man through the portal leading back to Earth, but the three heroes beat them back through the gateway, which is sealed by Portal. In another separate incident, the Mindless Ones invade and destroy much of
Times Square. A force that consists of Spider-Man,
Doctor Strange,
Cyclops,
Thor,
Iron Man, and the Fantastic Four help stop them, mainly by creating barriers. The Mindless Ones are temporarily defeated when
Mister Fantastic creates a machine that manipulates their magical energy, drawing them back to where they came from. This, inadvertently summons Dormammu, who battles Doctor Strange. One of the Mindless Ones punches Spider-Man, displacing him in time. After Spider-Man returns to the present, Strange banishes the Mindless Ones, leaving Times Square damaged but intact. Rorkannu, who physically resembles Dormammu and claims to be lord of the Dark Dimension, is stated to control a group of Mindless Ones. Emerging from a portal in a public restroom, they rampage through a small Colorado town, killing everyone they see, then wearing their clothing and behaving like them. The Mindless Ones appeared in an issue of
Cable & Deadpool in which
Deadpool and
Bob, Agent of Hydra encounter them in their own dimension. The two are being manipulated by Doctor Strange. The Mindless Ones alternately attack and worship the two protagonists, evidently mistaking the light from a
glow stick for a magical power and revering whoever it seemed to be emanating from. Deadpool and Bob end up causing the deaths of several Mindless Ones as a needed sacrifice to close down a magical catastrophe threatening innocent lives. Plokta, a Duke of Hell, decides to conquer the world exponentially from a tower block in
Birmingham. He used the collected magical energy of people captured within its rooms to create an army of Mindless Ones, but was eventually stopped by
Captain Britain and MI13. Plokta is revealed to be the original creator of the Mindless Ones and was responsible for them within the hierarchy of Hell. The Mindless Ones are used to mine Neutron Stars and many other ultra-dense gravity sites. They rebelled against their slave masters and began manufacturing a drug called "Krush" from the surface of Neutron Stars. They are members of the Black Hole Sons and it seems they are led by a being called The Mind who is currently held prisoner in a
Nova Corps ship. During the "
Original Sin"' storyline, a Mindless One was wrecking New York and smacking the Thing around. Spider-Man shows up to give Thing a hand. Spider-Man recognizes the Mindless One and realizes that they are not supposed to be telepathic. The Mindless One screams in agony over the things he has seen and the things he has done. Thing realizes he is wielding the
Ultimate Nullifier and tries to talk the Mindless One down. However, it does not work and the Mindless shoots himself with it. By this time,
Nick Fury and the Avengers arrive.
Captain America wants the Ultimate Nullifier left alone until it is contained and Fury declares the battle zone a murder scene. Elsewhere, a group of villains realize the other Mindless Ones are evolving. Doctor Strange later encountered a Mindless One known as the Mindful One. It is a servant of
Isaac Newton, who enhanced it to serve him. After some adventures, the Mindful One moves in with Doctor Strange. In
Strange Academy, the Mindful One and several sentient Mindless Ones join the eponymous academy as teachers. ==Powers and abilities==
