I think she's the same girl who gets lost onboard the ferry to Vermilion City in G/S/C and HG/SS, because she also gets lost and her father takes on the appearance of a Gentleman, as he did in FR/LG.Oh yeah, that girl was Lostelle. It's definitely scary to hear that the Hypno scare her but I think she went to the Berry Forest to pick Berries as usual but in that moment she just became scared because a Hypno approached her.
The manga characters are a lot wackier too. Emerald is a good example: he gets picked on because of his small stature, he likes inventing his own gadgets, and... he pees off tall buildings, at least in the Japanese version. And the same panel it happens in strongly implies that Sapphire and Ruby got caught in the stream. In the English version, it gets changed so that he's pouring some soda out of the window, which isn't as disgusting as the former, but still messy.Seeing all that stuff on the internet was what first made me check out the manga, and I did end up loving it for the slightly more unpredictable, violent tone.
Oh, and... breasts. Misty and Sabrina are the obvious victims. And Misty's only 10.
