Voice Range: Low to Mid-Low

Enkidu is a muscular old member of Amnesia that was scouted out by Hilda after hearing of an In-birth who relied on his martial prowess over his EXS abilities. A skilled practitioner of his family's ancient martial arts, Enkidu deliberately got himself bitten by a Void so he could become an in-birth and battle Gordeau, the "strongest In-Birth" and reach a new plane of competition beyond normal humans. Enkidu's motivations stem from the death of his late mentor and his feeling of powerlessness to help him inspired him to pursue strength in all things. He hopes that in the end he'll find enlightenment through the pursuit of strength and come to absolve himself of his mistakes.

Most of the time, Enkidu tends to keep to himself and won't speak unless he feels like it is necessary. He is a stoic, calm individual who is completely and utterly diligent when it comes to fighting. Despite that, Enkidu can be very humble and gets along well with his fellow comrades, especially Gordeau and Chaos, the latter being a good friend of his. Enkidu can also be somewhat witty and likes to poke fun at both Hilda and apparently Gordeau from time to time. Despite his calm and reserved exterior, Enkidu's inner thoughts have shown that even he has his limits when it comes to dealing with Hilda.

Enkidu has also stated to be uncomfortable with social gatherings, believing that he stands out too much. He compares it to "Inviting a clown to a funeral".

In terms of combat, Enkidu becomes a lot louder and excited sounding during a fight and he treats the art of combat incredibly seriously. He has nothing but the utmost respect to those who show resolve in combat and will react gracefully even when losing.
