Beelzebuth

"In the name of Raphael, I command you Consume all the magicules within this barrier Do not leave a single soul fragment behind"



Beelzebuth (暴食之王) is one of Rimuru Tempest's Ultimate Skills. It had evolved from the Unique Skill Gluttony at the cost of Merciless during Rimuru's Harvest Festival.

Abilities
Beelzebuth can absorb targets, as if it was a Black Hole (暗黒重力渦).

Sub-Skills

 * Predation (捕食): Absorbs the target into the body and can be used at range like Gluttony. If the target is conscious, however, the success rate greatly decreases. The affected targets include organic matter, inorganic matter, Aura, Magicules, Skills, Magic and even space itself. It also takes effect instantly, ignoring space and time.
 * Imaginary Space (虚数空間): A world of chaos. An ultra-evolved version of Stomach and Isolation with unlimited space. It is a prison where those who need to be quarantined are locked up. This ability was added to Beelzebuth during the events of The Abyss Unleashed.
 * Stomach (胃袋): Where all absorbed targets are stored. Items produced via Analysis can also be stored. Anything that is stored in the stomach is not affected by time. Its capacity has been greatly enhanced compared to Gluttony.
 * Isolation (隔離): Harmful materials or things unnecessary for analysis can also be stored. They will be used to replace magic energy.
 * Mimicry (擬態): Replicates the absorbed target's appearance. The skills and abilities of the target can also be used. However, this depends on the successful analysis and acquisition of relative information regarding the target.
 * Corrosion (腐食): The ability to decompose the target in conjunction with Predation. It also can add the abnormal condition of corrosion. There is a chance of acquiring an ability after consuming only a part of a target's body. However, the chance of that happening is less than consuming the whole body.
 * Soul Consumption (魂喰): The ability inherited from Merciless that can eat the Souls of targets and kill them anytime. It can be activated once the target's heart breaks. It also can be used to directly eat the target's Heart Core when left unprotected by their Spiritual and Astral Body. Like Predation, it also takes effect instantly, ignoring space and time.
 * Food Chain (食物連鎖): The user can freely copy the prototypes of the skill of any subordinates, while also enabling the user to grant subordinates any skill they are compatible with. Furthermore, the user's magicule levels also grow whenever the subordinates show any significant growth.
