Man, Perona’s such a fun character—her ghostly powers and that gothic lolita vibe totally stood out in 'One Piece' pre-timeskip. After the timeskip, she does make a comeback, though it’s not a huge spotlight moment. She pops up during the Wano arc, specifically in the 'Reverie' flashback segments, where she’s seen hanging out with Gecko Moria. It’s cool to see how her dynamic with Moria has shifted; she’s less bratty and more mature, which fits the post-timeskip growth theme Oda loves. I wish we got more of her, but hey, at least she’s not forgotten!
Her role post-timeskip is mostly tied to Moria’s storyline, which adds some depth to the whole Warlords’ fallout after the Marineford War. I’m low-key hoping she joins the Straw Hats’ allies in a future arc—imagine her ghosts messing with the enemies while Usopp freaks out. That’d be gold. For now, though, her appearances are brief but satisfying for fans who missed her quirky energy.
