4 types of Human-Abberant Pact
Contractors
Humans who are under the control of an Aberrant. Contractors have limited power depending on whether the Aberrant agrees with them. Most of them are unable to use the Aberrant's power at will and only when an Aberrant decides to.
Most likely will fall under most of humanity. Usually, an average or weak person can be overpowered by an Aberrant due to humanity's flawed nature (ex. physically/mentally weak).
Soul Parasitism
Humans who have merged their own soul with an Aberrant's soul, granting them extraordinary abilities at the host's will. One downside of this is the person's permanent abnormal appearance, becoming an outcast in human society. However, there are some who managed to conceal their horrid appearance in public.
This fate will fall under people who are broken, unwell, and unfortunate with their own lives. These are the type of people who crave unrelenting power and greed despite their own condition. Due to the unpredictable nature of the world, they will accept how life the way it is.
Possession
Humans who were deemed worthy by the Aberrant to use their soul as their source of power. One of the most versatile, as the wielder can unlock and unleash the Aberrant's fullest potential. The wielder must have a great bond and trust towards the Aberrant. Whenever the Aberrant notices a sign of betrayal. The Aberrant will devour the soul of the wielder, turning them into hollows. A lifeless and emotionless shell of a being without a soul.
Manipulative, charismatic, intimidating, and dominant people can achieve this incredible level of power. With this power, they will eventually become a completely dangerous threat in society.
Commanders
These are humans who can command their chosen Aberrant at their own will. They use these Aberrants as a trusty companion for self-defense and combat capabilities.
These people are truly unique and special in their own. They are mostly justifiable and are highly socially intelligent. These are the type of people who'll make you feel like you're meeting an angel and are also impossible to dislike.
