Osmosian

Osmosians are a subspecies of mutant Humans whose abilities are given by unique genetic components in their DNA. They were originally believed to a be species from the planet "Osmos V" before this information was revealed to be a hoax.

Anatomy
Being a Human subspecies, Osmosians are mostly indistinguishable from regular Humans. However, they can develop black markings around their eyes after absorbing energy.

Artificial Osmosians such as Aggregor have small flesh-colored horns on their forehead.

Diet
Osmosians normally eat food to sustain themselves. They prefer savories over sweets.

Osmosians are able to feed off the metabolism and life force of other living beings. However, this method of feeding can easily turn into an addiction, causing the Osmosian to become insatiable and instinctively seek out any possible source of energy to feed off of.

Powers and abilities
Osmosians are able to absorb, hold, redirect and discharge virtually any type of energy through their bodies.

As demonstrated by Kevin Levin, Osmosians can absorb the mass and properties of physical materials, coating themselves in the substance which allows them to take on its properties.

While not on the same level as Tetramands or Petrosapiens, Osmosians are naturally stronger and more durable than Humans. These abilities can be proportionally increased to whatever material they have recently absorbed.

When absorbing liquids such as water, Osmosians will gain the properties of that liquid.

When absorbing mud, Osmosians can have objects pass through them without causing physical damage.

When absorbing elastic materials, Osmosians can "sort of" become elastic.

Osmosians can regenerate when absorbing certain types of energy.

Osmosians can transform into other beings at will. For example, Devlin Levin can transform into "Devlin 11", a duplicate of Kevin's first major mutation "Kevin 11".

Other substances that Osmosians can use their absorption powers on include bubblegum and fire.

When Osmosians absorb the DNA and life force of other being, they gain that being's powers.

Weaknesses
An Osmosian's biggest weakness is their insatiable hunger for energy and becoming mentally unstable, and storing energy for long periods of time will worsen their instability. However, this is normally latent and becomes easier to control if they are mature and have experience with absorbing energy.

If an Osmosian is forcibly drained of the energy they have absorbed, it will present risks to their physical health if they do not seek immediate medical attention due to them living off energy instead of eating and sleeping properly.

By absorbing another being's DNA, Osmosians can only acquire the original creature's powers at 1/10th of their original potency. Any powers an Osmosian has absorbed from other life forms will eventually wear off and disappear. The more they absorb, the longer it will take for these powers to wear off.

The materials an Osmosian absorbs can put them at a disadvantage. For example, absorbing liquids weakens their durability, absorbing metal makes them vulnerable to electricity, and absorbing wood makes them vulnerable to fire.

Regardless of how much DNA an Osmosian absorbs, their own DNA will eventually overwrite the absorbed DNA in time, causing them to lose absorbed powers unless they keep reabsorbing to keep it from happening.
