Nephele (BNHA)

Fan Fusion: Nephele's quirk allows her to temporarily fuse her physical abilities and skills with those of any character she chooses from any fandom she's familiar with. By focusing on a specific character, she can tap into their unique abilities and harness them as her own for a limited time.

When Nephele activates her quirk, she gains the physical attributes, powers, and knowledge associated with the chosen character. This allows her to mimic their fighting style, utilize their special techniques, and access any specific powers they possess.

Drawback: However, using Fan Fusion requires a significant amount of mental and physical energy. The more powerful or complex the chosen character's abilities, the greater the toll it takes on Nephele's body. Prolonged or frequent use of Fan Fusion can lead to exhaustion, physical strain, and potentially temporary loss of her own quirk. Additionally, the time limit for each fusion is short, typically ranging from a few minutes to half an hour, depending on the intensity of the abilities being used.

Furthermore, Nephele can only fuse with characters she's familiar with. If she lacks knowledge or understanding of a certain character, their powers may not be accessible to her. She must continually study and engage with various fandoms to expand her roster of possible fusions, making it a constant learning process to fully utilize her quirk's potential.
