IFU is a sentient, monstrous version of iFunny's smiley face logo that appears in Legacy as an opponent and a playable character during Rattled. IFU is the disorderly result of an obstreperous dimension, namely one that she owns as she is the self-appointed warden and therapist of her realm. Does everything she can to help those in her dimension and stop threats. IFU is not evil; conversely, she is quite the opposite. Nice and social outside of Ifunny Hell and protective inside of it.
