Mitosin

Mitosin is a fictional element appearing in the Marvel Comics universe. It was first introduced in the comic book series X-Factor. Mitosin is a synthetic, bio-engineered substance created by the villainous scientist named Doctor Demonicus. Its primary purpose was to enhance the physical capabilities of those who were exposed to it, making them stronger and more resilient.

The substance itself is often depicted as a viscous liquid or gas. When introduced into a living organism, Mitosin triggers rapid cellular regeneration and mutation, leading to significant increases in muscle mass, durability, and in some cases, the development of new superhuman abilities. However, these enhancements often come with a cost. Prolonged exposure or high doses can lead to instability, madness, and eventual physical breakdown of the subject.

Doctor Demonicus utilized Mitosin in his attempts to create super-powered soldiers and to augment his own forces for his various schemes against the X-Factor team and other heroes. While the precise scientific explanation for Mitosin's effects is not deeply detailed, it is consistently portrayed as a potent and dangerous tool for biological augmentation. Its presence in a story typically signals a threat involving enhanced adversaries or a desperate race to counteract its harmful effects. The character of Mitosin is not a sentient being but rather a substance with specific, often detrimental, properties.
