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.

Sub-Skills

 * Predation (捕食): Absorbs the target into the body. If the target is conscious, however, the success rate greatly decreases. The affected targets include organic matter, inorganic matter, Skills, and Magic. Like with Gluttony, it can be used at a range and can now even affect space itself. It can absorb at least as far as a whole city's worth of Magicules.
 * 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 decomposition. 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): Only able to be activated when the targets lose their will to resist. Once that condition is met, from that point on, whenever the holder wishes, they can reap the marked target's Soul even if the target has recovered their will to live and fight in the meantime.
 * 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.
