|Manga Debut||Chapter 69|
They have the appearance of pulsating sludge, and if humans inject those cells into themselves, they supposedly start to exceed the limits of human beings and turn into monsters.
The Monster Cells also depend on the base natural power of the human itself to create monsters. The stronger the human, the stronger the monster it creates. This shows that humans with strong natural power are able to transform into more hideous creatures than weak people who still maintain a lot of their human appearance. Benpatsu, for example only gained a third eye, sharp teeth, and sharp nails after eating a Monster Cell. Stronger humans such as Choze, Volten, Hamakuchi, or Gouketsu have more monstrous, inhuman appearances.
When a human becomes a monster, they experience blood lust, sadism, ecstasy, insanity and a loss of both humanity as well as morality and even rational thinking in which they will bend only on mayhem and destruction. Furthermore, the transformation effect is also very similar to when a human takes steroids, with some hosts showing intense pain upon ingesting. In exchange for this they gain great strength that allows them to surpass their old limits. However, this is not considered a limit breaker since becoming a monster is just putting a new limiter on the transformed human. There is a particular weakness when a human becomes a monster is that he/she will become extremely reckless due to the blood-lust causes by the cell in which a newly transformed human can attack an opponent millions time stronger than them like Benpatsu rushes directly into Suiryu only to be killed by one kick to the neck or Bakuzan thinks he is stronger than all S-class heroes and even Gouketsu to which he attacks Gouketsu without hesitation only to be stopped by Gouketsu's superior strength. The Monster Cell also brings the worst of a human personality out when a human becomes a monster like in the case of Bakuzan not only the cell makes him more brutal and sadistic but also showing what he truly is from the deep of his black heart: the bully who want to become strong just to prey on the weak.
The monster cell must be eaten willingly or else the cell will have no effect. Apparently, eating more than one at a time, will knock out the consumer since the body of the human cannot handle the power of multiple cells at once. In this situation, the monsterfication will be halted for some time until it can be completed. It is unclear if the consumption of too many of these cells will result in death, and it's also unclear if eating multiple monster cells with multiply the consumer's power or if it will remain the same as if the consumer ate one.
The "Monster King" Orochi seems to be the source of the cells.
Gouketsu then gives the cells to his disciples, who become The Three Crows.
