When it came to designing the Tobi Roppo's hybrid designs it feels like Oda expended most of his creative juices early. Page One's and Ulti's were pretty cool but Who's Who was literally Lucci-but-tiger, Sasaki is just a bipedal Triceratops, and Black Maria's isn't even a proper hybrid form. Despite the animation chugging a bit Takagi's art and corrections were pretty great in the close ups and I'd completely forgotten about the reverse propeller joke; I knew some sort of fake out was coming from how that scene was being framed, but it still got me good.
So next episode they're reanimating parts of the Robin flashback huh? Hm, interesting choice. I wonder if young Robin is going to be recast since IIRC her voice actress was an actual little kid back in 2006.
