Dimple

Dimple (エクボ, Ekubo) is a self-proclaimed upper-class evil spirit who has aligned himself with Mob after being defeated by him.

Appearance
Dimple's distinguishing features are the red circles on his cheeks, which appear on the face of any human he possesses. His usual form is that of a wispy cloud of smoke, or, according to Teru, a "nasty-looking floating energy bulb". He occasionally grows arms, rarely legs. Even in his simplest form, his human-like face looks a little too detailed, with a prominent nose and lips.

Personality
Dimple wants to be a god. Specifically, he wants to be worshipped by all humanity. Despite having that kind of ego, he didn't hesitate to put himself at Mob's mercy in the hopes of using the boy to his advantage. At first, he wanted to steal Mob's body and use it to become a god, but he eventually decided to try to make Mob a god instead.

Dimple does not consider himself "dead".

(LOL) Cult Arc
Dimple founded a cult known as "(LOL)" (originally (笑) in Japanese), a laughter-based gathering that managed to amass several dozen people in only a month. When a member of (LOL) happened to bring Mob to a meeting, an ordeal ensued and ended in Dimple's defeat. Dimple showed up at Mob's house the next day and started following him around.

Teruki Hanazawa Arc
When Teru challenged Mob to use his power, Dimple stepped in to defend Mob but was almost completely obliterated by Teru.

Big Cleanup Arc
After recovering from being reduced to the size of a dust mite, Dimple went to the Kageyama residence. He couldn't get in due to a spiritual barrier around the house. Ritsu encountered him there and accidentally let him inside. The two ended up working together.

7th Branch Arc
After Ritsu tried to start a fight with Mob and was suddenly kidnapped, Dimple joined Mob and Teru on a mission to invade the 7th branch of Claw and retrieve Ritsu. Dimple possessed a nameless security guard. Dimple got defeated by Matsuo and subsequently captured. When he was released, he easily defeated Matsuo.

Urban Legends Arc
He possesses Banshomaru Shinra to fight The Dragger. He lasts long enough for Mob to show up and exorcise the dragger.

Keiji Mogami Arc
He realizes the spirit possessing Minori is Keiji Mogami and warns Mob to run away.

Normal Dimple
Before being defeated by Mob, Dimple was a powerful upper-class evil spirit; he himself had stated he had gone through hellish battles to attain his levels of power. He showed the ability to regenerate from damage, transform different parts of his body and even fire laser beams from his mouth. However he was still barely a match for powerful espers such as Mob, Keiji Mogami, or even Teru.

After being defeated by Mob, Dimple lost much of his power, but still retained some of it. Dimple's main ability in this form is possessing humans and controlling them from inside. With more power he has also shown the ability to hypnotize and manipulate masses of people using mind signals without much effort.

God Dimple
When Dimple fused with the Divine Tree, resulting in the creation of Psycho Helmet, Dimple's power grew to what he described as "godlike" levels. Through the Divine Tree Dimple's influence he could hypnotize anyone who so much as touched or consumed matter from the Divine Tree. He also controlled Psycho Helmet, which was powerful entity of its own, and could manipulate the matter of the Tree itself. Dimple also got a personal power boost that increased his abilities further than even that of his original powered-up form. He was extremely excited to have this new power and came up with all sorts of specially-named attacks.
