Naruto: Lord of Space

Lin Chen: Born into an ordinary family of Konoha's lower-ranking ninja, with no distinguished lineage. His talent for taijutsu is average, even slightly below par. He's resilient, optimistic, and clever in his own way, but at first, his lack of strength often makes him the target of ridicule from his peers, especially some members of the Uchiha and Hyuga Branch Family.

Mutated Devil Fruit: A strange fruit that accidentally fell into the Hokage world, or was discovered in some ruins. It resembles a pineapple, but its surface bears rippling spatial patterns. In essence, it is an adaptation of the Space Fruit to another world. After Lin Chen eats it, it has none of the Devil Fruit weaknesses from the pirate world, such as vulnerability to seawater and Seastone, nor does it cause a bloodline disease. Its power merges directly into Lin Chen's chakra system, creating a one-of-a-kind Space Kekkei Genkai.
