Inner Monster

Imagine this, one day you’re walking down the street when you suddenly black out and wake up to see scientists all around you. They inform you that you have come down a supernatural medical condition that causes you body to manifest itself an inner entity in order to cope with the sudden arrival of supernatural abilities. They tell you that these entities often listen to their host, however can often be violent and murderous, only coming out when the hosts life is in danger or when under extreme emotion. They tell you that you are unable to use these abilities but the monster can intuitively know how to use these abilities to their maximum potential. They also tell you that you can manifest any supernatural ability within your monster as you please and there is no limit to the amount of power you can manifest, however there is a limit on how powerful these abilities are. They decide to let you go as you are too dangerous to keep locked up and you go on your merry day with this new Knowledge.

What abilities would you have and how many?

What would you do with this monster?

What would it look like or what would it’s personality be? (Optional)

Rules:

There is no limit to the amount of abilities that you can manifest within you monster.

You can manifest any supernatural ability you want but you can manifest any absolute, meta, Omni, primordial, etc powers. However you manifest certain OP powers as long as they are not too broken.

You cannot manifest your monster at will, only in dire situations such as extreme emotion or life or death situations and you only get limited control over it with it following your last desires before you transformed.

Can’t alter any aspect of it’s personality or give it powers in order to make it more Loyal to you.

Other than that, have fun with your inner monster. :)
