Predator

Predator (捕食者) is Rimuru Tempest's very first Unique Skill.

After the battle against the Orc Disaster, Rimuru ate (predated) him and obtained the Unique Skill Starved, which was then fused with Predator to evolve into Unique Skill Gluttony, though during the process the "Analysis" aspect was absorbed by Great Sage instead.

Effects

 * Predation (捕食): Absorbs the target into the body. However, if the target is conscious, the success rate greatly decreases. The affected targets includes, but isn't limited to: organic matter, inorganic matter, skills, and magic.
 * Analysis (解析): The absorbed target is studied and analyzed. Craftable items can then be produced. If the required materials are present, duplicates can be produced. In the case of successful skill or magic analysis, the same technique can be acquired.
 * Stomach (胃袋): The target can be stored. Items produced via Analysis can also be stored. There is no storage time limit.
 * Mimicry (擬態): Replicate the target's appearance. The skills and abilities used by the target can also be used. However, this depends on the successful analysis and acquisition of relative information regarding the target.
 * Isolation (隔離): Materials harmful or unnecessary for analysis can also be stored. They will be used to replace magic energy.

Trivia

 * There was a certain wordplay that got lost in translation, involving this Skill:
 * Up until the Orc Disaster battle, Rimuru and Great Sage called the Skill
 * Predator (捕食者),
 * so when the LN chapter / manga chapter / anime episode titled
 * Devourer of All (全てを喰らう者)
 * came around, the first assumption was that the title was refering to Orc Disaster Geld due to how omnious and wicked it sounds, however when Rimuru changed the way he called the Skill, refering to it as
 * Predator/Devourer (捕食者)
 * instead, it revealed that the title of the chapter/episode was infact refering to Rimuru himself as the "Devourer of All"
