Herohero

Herohero (ヘロヘロ) is a guild member of Ainz Ooal Gown and regarded as one of the Forty-One Supreme Beings by the NPCs of the Great Tomb of Nazarick. He is the creator of Solution Epsilon and one of the creators of the Homunculus Maids groups that work in Nazarick.

Appearance
Herohero is an Elder Black Ooze, one of the strongest slime-type race. His appearance is merely a mass of a black, sticky substance. His tar-like surface roils and writhes continuously, never staying in one shape for more than a second. In the Anime, he looks like a blue slime.

Personality
Herohero has a polite and humble personality. He enjoyed the game a lot and was hoping that there will be a YGGDRASIL II, so that they can play again.

Background
As one of the four remaining guild members in Ainz Ooal Gown, Herohero logged in to YGGDRASIL and spent a short amount of time together with Momonga.

Two years ago, Momonga stated that Herohero had stopped actively playing the game right after he changed his job in real life.

Apparently, Herohero's job takes a great toll on his body in the World of 2138 as he had been overworking himself. It was to the point wherein which he had to go to the doctor to check for any sign of illness.

The Undead King Arc
Herohero is one of the four remaining guild members of Ainz Ooal Gown to return to YGGDRASIL before its shut down. He talked with Momonga about the current status of the Guild and Nazarick. Herohero thanked him that they were able to enjoy the game to its fullest because of his presence and bids farewell to Momonga and logs out.

The Ruler of Conspiracy Arc
When Ainz decided to turn the Sorcerer Kingdom into a utopia, Ainz made a vow to Herohero, in his mind that he will not be a terrible ruler like a boss of a black-hearted enterprise.

Abilities and Powers
Herohero's race is an Elder Ooze, which is famous for their specialty in acid-type attacks. His job class is filled with monk-type classes though it's not very good at damage dealing itself. However, its powerful acid is very effective on PvP and PK battles, by dissolving the enemy player's equipment. His class levels strengthened his corrosive abilities, to the point where they could even break immunities, allowing him to dissolve the equipment worn by enemy players. In this way, he traumatized the enemy.

Momonga

Quotes

 * (To Momonga): "Ah — seems about right — wah, it's been so long...This is bad. I've been doing so much overtime recently that my sense of time is starting to go weird."
 * (To Momonga): "My body? Well, it's a mess. I haven't had to see a doctor yet, but I'm almost there, it's really bad. A lot of times, I feel like I want to run away from it all, but then I think about how I need money to live and then I go back to work like a whipped slave."
 * (To Momonga): "Momonga-san, you must have kept the guild going as its leader so we could come back to it at any time. Thank you very much."
 * (To Momonga): "Yes. We had fun with the game because you were our guild master, Momonga-san...I hope that when we meet again, it'll be in YGGDRASIL II."
